Presentation The African-American social gathering can be depicted with the assistance of such models as natural control, organic varieties, social association, correspondence, space, and time direction. These components influence the arrangement of human services administrations to African Americans. They decide the viability of the American social insurance framework among various ethnic groups.Advertising We will compose a custom report test on African-American Cultural Group explicitly for you for just $16.05 $11/page Learn More Environmental control Some African Americans practice natural control by sticking to their convictions and social practices. Thusly, the people, who trust in customary medication, are dubious of current treatment techniques (Dayer, 2010). Along these lines, more agents of this gathering may look for the administrations of society healers before looking for present day clinical cures. This training is imbedded in numerous customs that they despite everythi ng watch today. In addition, they doubt the American human services framework because of the impact of the Tuskegee syphilis study and different infringement of their social equality. Natural varieties The investigations have uncovered that hereditary cosmetics, enzymatic varieties, and defenselessness to sicknesses are the primary purposes behind commonness of specific maladies among African Americans. These ailments incorporate malignant growth, asthma, coccidioidomycosis, lactose narrow mindedness, and sickle cell iron deficiency (Dayer, 2010). For instance, the HbSS genotype gave from guardians to offsprings causes sickle cell frailty. The commonness of the malady is somewhere in the range of 8 and 10 percent (Spector, 2004). Additionaly, hereditary varieties decide the degree to which natural variables and financial develops influence the strength of African Americans. Social association African Americans append significance to family and religion. For instance, they treasure m ore distant families, network associations, and strict fellowship. Since the times of subjection, African Americans have kept up solid social binds so as to hold the feeling of network and having a place (Spector, 2004). For instance, slaves utilized profound imagery to give trust in opportunity. This inclination has prompted solid church affiliations that are as yet present today. Additionally, strict and social gatherings were significant for tending to social, political, and financial difficulties looked by this gathering (Dayer, 2010). Correspondence The portrayal of correspondence style is legitimate in light of the fact that African Americans utilize various dialects and vernaculars. They rose during the times of servitude. Aside from English, one can recognize French and Spanish. Particular language designs rose during the time of servitude when dark individuals needed to learn new dialects so as to speak with each other (Spector, 2004). Slave proprietors debilitated the corr espondence between individuals who communicated in a similar language since this association could have prompted uprisings. This partition added to the improvement of lingos, for example, pidgin and Creole (Spector, 2004). Also, African Americans depend on non-verbal correspondence. For instance, they dishearten direct eye to eye connection in specific circumstances and use quietness to communicate outrage and disappointment. Individual space I concur with the depiction of African Americans’ way to deal with individual space since it is controlled by their social nature. They are not extremely touchy to the idea of individual space since they are accustomed to cooperating and dealing with one another. It ought to be referenced that numerous African Americans support eye to eye connection.

African Americans are slanted towards managing occasions and difficulties that are identified with the most short term. Along these lines, they think about arrangements and numerous different exercises as adaptable and flexible (Spector, 2004). This quality recognizes them from other social gatherings. How profoundly I relate to the legacy I distinguish emphatically with the African-American ethno-social legacy. I append significance to such qualities as solid social and strict affiliations, open correspondence styles, unmistakable language examples, and accentuation on present time direction. Also, I am of African-American starting point. A few wellbeing convictions are remembered for the social legacy of this gathering. They incorporate the intensity of so ciety medication, recuperating impacts of herbs, mending forces of root and herb specialists, and the capacity of profound healers to avert malice and diseases.

African List of chapters Introduction Existence of Math Performance Gap Causes and Explanation of Math Performance Gap Conclusion Works Cited Introduction The conviction that Black understudies have more regrettable execution in math in examination with their White colleagues has flourished among instructors, understudies, educational plan engineers and researchers.Advertising We will compose a custom research paper test on African-American Students and Mathematics Achievement Gap: Stereotype or Reality? explicitly for you for just $16.05 $11/page Learn More It is conceivable to expect that it ascends from the primary long stretches of the â€Å"post-Brown v. Leading body of Education case† period when the â€Å"separate however equal† regulation and isolation in training were proclaimed unlawful (Martin 121), and when Black and White understudies started to learn together. Today numerous educators have acknowledged this announcement as given and adjust their instructing moveme nt to it. In any case, today the subject of Black students’ poor accomplishment in science stays consuming: understanding its legitimacy and, on the off chance that it is legitimate, its quintessence and source is significant, as it might give instructors important foundation for creating proper way to deal with showing Black understudies. Furthermore, this information might be significant for Black understudies themselves to improve their self-adequacy. The motivation behind this exploration is to discover whether there is the proof of the math execution hole among Black and White understudies and, in the event that we find that it exists, to toss ling upon its root. There are a few theories that we have to check: The science execution hole among Black and White understudies exists. The current hole among Black and White understudies is brought about by social or intellectual idiosyncrasies of Black students’ thinking and learning. The current hole among Black and Whi te understudies is brought about by Black students’ low inspiration to considering science. The current hole among Black and White understudies is caused or disturbed by the normally acknowledged negative generalization. The current hole is caused or bothered by some different elements. We will watch sources committed to the subject of our examination and test these theories. Presence of Math Performance Gap Several examinations substantiate the announcement about presence of the math execution hole among Black and White understudies; quantitative assessment of their exhibition had been completed for quite a few years. As indicated by Rothman, the hole has diminished considerably during the 1970s-80s, yet in the late 80s, the advancement â€Å"stalled† (refered to in United States Commission on Civil Rights 9). In 2000, the hole despite everything existed: while around 40 percent of white fourth grade students’ math execution was at or above capable, just 5 perc ent of Black understudies performed at a similar level (10). Besides, Fuetsch and Ware (in Hayman and Ware 307) express that during the examination completed somewhere in the range of 1995 and 2004, every year the hole was greater than in the start of the perception in any event in one of the watched grades.Advertising Looking for inquire about paper on instruction?

As indicated by the consequences of the 2006 examination of school students’ tests results introduced in (Anderson), Black understudies were 41 focuses behind non-Hispanic understudies. Paige and Witty (35) express that in 2007, the contrast between various White and Black fourth graders who performed at or over the capable level was 51 percent White versus 15 percent Black; in the eighth grade, 82 percent of White understudies performed at or over the f undamental level versus 47 percent of Black understudies. Moreover, the examination in (Anderson) showed that there is no solid relationship among's age and execution in math: the hole fluctuated in various evaluations. At long last, the hole in math was greater than that in different subjects, which makes concentrating of math accomplishment hole separated from holes in different subjects sensible. This gives us chance to express that there are sure factors past ethnicity itself and students’ age that effects Black students’ execution in math. A few proposals on these components were communicated in the theories detailed in the presentation. We will talk about them in the following section. Causes and E

Standards of Economics - Essay Example Other huge component of this market model is the nearness of a lot of non-value rivalry as authority over cost is constrained by their common relationship. This is one of the critical practices of oligopolies with regards to their evaluating system. To have a superior comprehension of this oligopolistic estimating conduct, we will receive a game hypothesis model and utilize the framework outlined beneath. FIGURE 1. GAME THEORY AND PRICING STRATEGY Applying game hypotheses in evaluating techniques work like what is appeared in Figure 1. Assumed we have the two oligopolists, Firm 1 and Firm 2 and each can pick either a high or low cost. Their result lattice shows that if the two firms will pick a significant expense, each will make $6 million however on the off chance that both chose to sell at a low value, each will make $4 million. Notwithstanding, in the event that one of them picks a significant expense and the other one picks a low value, the low-evaluated firm will make $8 millio n yet the extravagant firm will just make $2 million. In this way, they will wind up charging the low cost since it is the prevailing system. Oligopolists who are autonomous rival regard to cost and this will result to bring down costs and lower benefits. Shoppers will wind up profiting by this. Then again, the oligopolists are at detriment since they will encounter lower benefits than if the two of them had charged significant expense. To maintain a strategic distance from the result lower benefit, they would prefer to decide to conspire than to build up cost seriously or autonomously. However, the beneficial outcome of conspiracy on assortment and quality more than repays buyers for the negative impact of deceitful costs, so shopper surplus is bigger with intrigue (Pakes 2000, p.1). Intrigue is a circumstance where firms act together and in consent to set cost of the item and the yield each firm will create or decide the geographic territory wherein each firm will sell (McConnell and Brue 1993 p.224). It might be in an unmistakable or undercover structure. The most extensive type of a clear intrigue is the cartel which normally includes a composed concurrence regarding both cost and creation. Cartels can control yield by ensuring that the market is shared among individuals and the concurred cost is kept up in the market (Lande and Marvel 2008, standard. 2). The Organization of Petroleum Exporting Countries (OPEC) is one of the best oil cartel on the planet. There are nations like United States where cartels are unlawful and there is an exacting authorization of hostile to confide in laws (Danieljensenlaw.com par.2). Thus, in cases this way, oligopolists will in general connive verifiably This should be possible through inferred plot. â€Å"Tacit collusion† need not include any â€Å"collusion† in the lawful sense, and specifically need include no correspondence between the gatherings. It is alluded to as unsaid plot simply because the result (a s far as costs set or amounts created, for instance) may well look like that of express intrigue or even of an official cartel. A superior term from a legitimate viewpoint may be â€Å"tacit coordination† (Marc, Julliene and Rey 2003, p.4). This might be found in type of a value administration. In the hypothesis of value administration, the essential supposition that will be that the prevailing firm-for the most part the biggest or the most productive firm in the business sets the cost and permits different firms to sell everything they can at that cost

What is Food - Free Essay Example

Food. What is food? Most consider food to be the one constant in our lives. It has played a significant role in human society and culture. Even specific foods are associated with specific regions. For example, tomatoes originated in the Andes in South America. Rice originated in Southeast Asia and wheat was first grown in Southeastern Turkey. Food culture can often be seen as a way to understanding society, history and the world. According to Dr. Siu Yau-ho of the Linguan University in Hong Kong, China; food culture can be broken down into two types of knowledge: material and intellectual knowledge. Material knowledge involves experience through the tangible sense, particularly through taste and smell. Intellectual knowledge involves experience through history, customs/traditions, religion, culture, geography, etc. â€Å"Dr. Siu said that food culture is not only close to life, but also an entry point and important channel of cultural communication, helping people understand the world.† Food Culture, 2018 Food has also played a significant role in religion. It is considered the basis of human culture. Not only does it play a significant role on the body but also the spiritual body. In most religion, food is considered sacred and doesn’t have a monetary value. Often the value of food is linked to identity. For example, rice in Japanese culture holds great significance. The emperors were considered incarnations of the god of mature rice. In Hopi Indian tradition and culture, corn represents the cycle of life and perseverance. Many are familiar with anthropologist Ludwig Fuerbach’s famous quote, â€Å"man is what he eats.† Ludwig conducted extensive research on the connection between the human psyche and the body and emphasizes the importance of nourishment and diet. In modern day society and culture, food has a considerably different ethic. Often food is received through secondary and tertiary sources (supermarkets, fast food, restaurant, etc.). There is a prominent trend among the U.S. population where people don’t really know where their food comes from. This is one of the biggest questions concerning food security. According to the USDA, food security can be broken up into four basic categorical levels: high food security, marginal food security, low food security and very low food security. High food security characterizes residential areas where there isn’t food access limitation. Marginal food security focuses on areas that have little indication of food access limitation and there is only â€Å"anxiety over food sufficiency or shortage.† Low food security denotes the reduction of quality, variety, desirability of diet and food intake. Very low food security shows multiple indications of lack of food access and reduced food intake. In 2006, the Committee of National Statistics (CNSTAT) classified â€Å"food security† as household-level economic and social condition. The USDA additionally revised its definition of â€Å"food desert† as â€Å"parts of the country vapid of fresh fruit, vegetables, and other healthful whole foods, usually found in impoverished areas. Largely due to lack of grocery stores, farmers’ markets and other healthy food providers.† Essentially food deserts are classified as low-income residential areas and communities where the closest supermarket or grocery stores is within a one-mile radius. Research and study have shown that there the lack of access to nutritional food has a severe impact on overall community health. Additionally, there are several factors that contribute to the stigma of food deserts such as lack of access to transportation, location, socioeconomic status, cultural, shopping/dietary habits, time/availability, etc. RESEARCH QUESTION I am studying food security within an urban environment because I want to find out how lack of food security can impact a community’s health in order to help my reader understand the topic of food deserts within the United States and create sustainable solutions to this issue. This question is feasible due to the abundance of information regarding nutrition and health. Additionally, several studies have been conducted regarding the topic of food security globally but particularly within an urban environment. I’m also researching several articles that analyze a multitude of sustainable solutions to the issue of urban food deserts. Before analyzing the topic of community health within an urban setting, we have to examine certain concepts that fuel this issue. One of these concepts is community food security (CFS), which suggests the main issue: food deserts. According to Meenar (2017), community food security is â€Å"having access to affordable, safe, culturally appropriate, and nutritionally adequate food† (Meenar, 1). This occurs through environmentally and economically stable food systems, which promote community involvement and active participation. CFS is often associated with the three main driving factors of food access: geographic, economic and informational (Meenar 2017). This concept plays a key role in the interconnection between socioeconomic status and accessibility to basic necessities. â€Å"Due to lack of food access, many lower-income families in U.S. urban neighborhoods are forced to seek assistance from federal programs and local food cupboards (Nord et al. 2009); however, many face challenges in doing so because of eligibility issues, lack of food availability, and poor quality of food† (Meenar, 2). Most low-income residence rely on cheap, non-nutritious food mostly due to convenience, abundance, and affordability. This additionally often pose threats and negative changes to health. When examining the definition â€Å"food desert† given by the USDA, this concept of community food security becomes validated. According to the USDA (2012), food deserts are classified as low-income residential areas and communities where the closest supermarket or grocery store is within a 1-mile radius. This implies that regardless of the food source or quality of food, a community is considered to be economically and socially adequate in accessibility to â€Å"safe† food. However, both Meenar and Pascale et al. argue that this is misleading and provides a false pretense of food accessibility. Meenar argues that the â€Å"urban-food† paradigm is much more than an issue of accessibility. He mentions several overlapping topics such as racial inclusion, food habits, including nutrition and health; therefore, scrutinizing the administrative definition of â€Å"food desert† and â€Å"accessibility.† â€Å"†¦this study argues that the concept of food environments in urban neighborhoods goes beyond typical food access and food desert analyses, which primarily use GIS data, including locations of supermarkets or grocery stores, median household income, population density or car ownership†¦ Food environment research [U.S] has relied heavily on†¦ U.S Department of Agriculture’s (USDA) food desert maps or The Reinvestment Fund’s (TRE) low-access maps†¦Ã¢â‚¬  (Meenar, 2). The maps and data taken by the USDA and TRE display information that negates the official USDA definition, as many disenfranchised areas have access to small local grocery stores but the â€Å"quality or quantity of fresh and healthy food is not guaranteed, and these foods are usually more expensive† (Meenar). Meenar also noted that even though people may have â€Å"food† access, they aren’t guaranteed â€Å"economic† and â€Å"cultural† access. However, Pascale et al. approach this discrepancy from a slightly different angle. Unlike most studies, Pascale et al. analyze communities that are considered food deserts due to lack of mainstream markets but consists of local ethnic markets, as food deserts shouldn’t necessarily indicate the absence of or limited access to food in â€Å"poor and racially diverse communities† (Pascale et al. 2017).

Hobbyist Short Story and Druggist Essay - 786 Words

Summary The short story, â€Å"The Hobbyist written by Frederic Brown is about a man named Sangstrom. Sangstrom was at a prescription pharmacy secretly talking to the Druggist about buying an undetectable poison to kill his wife. The Druggist asks to follow him into the back room and puts some coffee into the boiler. The Druggist informs Sangstrom that he feels that he deserves the poison for free but must pay for the antidote. This is when Sangstrom realizes that the Druggist had poisoned his coffee. Sangstrom panics and pulls out his gun and points it at the Druggist. The Druggist continues to explain that if Sangstrom hands over $1000 and writes a confession of the murder of his wife and the Druggist in case he did kill either one of them,,†¦show more content†¦Please help spread the word about my undetectable poison, will you? One never knows, Mr.Sangstrom. The life you save, if you have any enemies, just might be your own.† This proves how through blackmailing people he tries to save lives. The Druggist is brave because the text says, â€Å"Or if you think I’m bluffing, that you’re really not poisoned, go ahead and shoot.† This proves that he wasn’t scared of the gun. The Druggist is a careful man because the text says, â€Å"Whom do you want to kill and why?† This proves that he wants to know everything in the mind of the murdered before he gives anything to him. Sangstrom is the antagonist in the short story, â€Å"Hobbyist†, written by Frederic Brown. He is the person that opposes the Druggist. Sangstrom like the Druggist is also a mixture of both rounded and dynamic characters since he has many sided and complex personalities that you would expect of actual human beings but also has a personality that changes for the better and worse by the end of the story. For example, at the beginning of the story Sangstrom is reflected as a typical bad or villainous type person wanting to kill his wife. However right after the climax, just like a villainous character, his reaction to being blackmailed was pointing his gun at the Druggist. Sangstrom was forced into not killing his wife in the fear of getting caught by the police if the confession letter was mailed.

Essay on A Cure for Alzheimers - 1614 Words

A Cure for Alzheimers In February of 2000, I lost my grandmother to Alzheimers disease. She was diagnosed with the disease just less than two years prior to her death. Throughout that time, I watched changes in my grandmother that made her seem like an entirely different woman to me. She gradually began losing her short-term memory and we began to see signs of her long-term memory degrading too. It began to get harder and harder to take her out into public without being afraid of what would happen next. Her emotions would fluctuate with the changing of each minute it seemed.

Most often the disease shows itself in the elderly around the age of about eighty, and is rarely seen in people under the age of sixty-fi ve. One of the characteristics of this disease that makes it so hard for scientists to find a cure, are the numerous factors that present themselves in different patients. It seems as if no two cases of Alzheimer’s can be exactly alike. In 1906 a physician, named Alois Alzheimer, cared for a fifty-one year old patient with severe dementia. Upon her death, he was able to examine her brain at autopsy. Dr. Alzheimer was able to take advantage of recent innovations in microscopy and histological techniques that allowed him to study in detail the cellular components in nervous tissue. He found that the brain of his patient had severe cortical atrophy and described the neurofibrillary bundles and plaques that are now the hallmark for definitive diagnosis of what he at that time called â€Å"presenile dementia†. An account of his first patient was published in 1907. It is a little ironic that reevaluation this case has lead some to believe that this first patient did not s uffer from the Alzheimer’s disease at all.

Question: 1. Research into the different types of biometric systems which are currently available for access control systems. 2. Other than security concerns, privacy is considered a core value and is recognized either implicitly or explicitly as a fundamental human right. Privacy-enhancing technologies (PETs) can be defined as technologies that enforce legal privacy principles in order to protect and enhance the privacy of users of information technology. Research and discuss three PETs which can be used on the Internet. 3. Wireless sensor networks (WSNs) can be described as a network of nodes that makes a collaborative effort in sensing data around its periphery and its surrounding environment. Research into the area of WSNs and understand the WSN architecture and protocol stack. Discuss three different types of threats and vulnerabilities which can be used to attack the WSN. Give your recommendations on how the threats and vulnerabilties can be mitigated for the WSN. Answer: Answer 1 Biometric system is a technology-based system that uses some distinct information of a person to identify that person. These systems mainly rely on a specific data or biological traits of a person. The statistical analysis of peoples physical and behavioral characteristics is used as an identity of a person. These systems control the access of the restricted areas or systems by allowing only the authorized person to access the system or the area. Biometric access control systems ensure that right level of security is enforced within a specific system or place. The components of the biometric system include a metal oxide semiconductor or a charged coupled device for some particular systems (Banerjee Woodard, 2012). A biometric access system helps to transfer a biometric trait of a particular person in electrical signal that helps in identifying a person. The biometric access control system is mainly of two types, physiological and behavioral biometric system. The physiological biomet ric system consists of fingerprint recognition, face recognition, iris recognition, voice recognition, palm print recognition, gait recognition and so on. Out of these, face recognition, palm print recognition and gait recognition are discussed in the next section. Face Recognition Face recognition captures the digital image of the person and verifies the identity of the person by comparing and analyzing the different patterns of the image. This is one of the most commonly used biometric systems for security (Beveridge et al., 2013). The data of the nodal points of a digital image is captured, which is then used for verification. The advantages and disadvantages of face recognition are as follows- Advantages The advantages of using face recognition biometric system are as follows- It is a user-friendly biometric recognition system It is one of the most inexpensive techniques of verifying the identity of a person. It is a non-contact technology, as cameras are used for collecting the necessary information for identifying a person. Offers high speed identification in comparison to other biometric system Disadvantages The working principle of the facial recognition algorithm is largely dependent on the quality of the image. The relative angle of the targets face largely influences the recognition score. It requires a significantly larger storage space. Palm-print Recognition Palm print recognition is another biometric access control system that makes use of a scanning device to process an image data of a users palm and compare it with a stored record (Cappelli, Ferrara Maio, 2012). The advantages and disadvantages of palm print recognition are as follows- Advantages The advantages of Palm print recognition are as follows- The palm area is much larger and therefore it helps in capturing and analyzing the features of human hand more distinctively as compared to a fingerprint. Palm print recognition system can be easily integrated into other systems and devices. Disadvantages The disadvantage of palm print recognition is as follows- The system requires a large surface area and therefore, the entire device becomes larger in size. This increases the cost of the system as well. Gait Recognition This is a biometric method that deals with unique biological and behavioral characteristics of a user such as fingerprint or face. It is s systemic study of human motion and makes use of instruments in measuring the body movements and body mechanics. The advantages and disadvantages of gait recognition are as follows- Advantages The advantages of gait recognition are as follows- It is a contact less method as a gait recognition system can recognize a person from a distance Effective in use even in low-resolution image It is a non-invasive biometric technology Disadvantages The disadvantages of gait recognition are as follows- It may not work properly if a person changes or modifies its style of motion Even the surface of motion largely influences the gait recognition system. Answer 2 Privacy enhancing techniques refers to standardized methods of protecting the privacy of the stored data over internet. It considerably helps in protecting the privacy of the online users. It enforces legal privacy principles for protecting and enhancing the privacy of the users (De Cristofaro Wright, 2013). The three different Privacy Enhancing Techniques that can be used on internet are discussed below- Email Anonymity The email anonymity systems ensure that a particular email is sent without revealing the personal information and identity of the user. Use of remailer is prominent in achieving the email anonymity (Rainie et al., 2013). The working principle of the remailer is that, when a user sends an email, it at first goes to the remailer. The remailer in turn strips off the identification information of the user and re-mails the message to the intended recipient (Froomkin, 2015). Type-III remailer is an advanced remailer that provides efficient protection against the replay attacks. Interactive Anonymity With the advent of technology and internet, real time online interaction is increasing as well. An attacker can intercept these communications thus leading to the information loss or modification of the information (Larsson et al., 2012). An information can be modified during its transmission. Different internet applications such as, remote login and voice over IP posses significant threat to data privacy. In order to eliminate such risks, different systems are implemented over the years that provide practical security and privacy to the users. The examples of different systems that maintains the privacy of the of the users data over internet includes use of onion routing, freedom network, Java Anon Proxy, Tor and so on (Li et al., 2013). Communication Privacy Systems The communication privacy systems ensure that the identity of a user communicating over internet is kept private. The aim of this Privacy Enhancing Technique is to keep any information flow private from the third parties. Different techniques are applied to protect the information if a user wishes to keep the contents of a particular communication private (Wessels et al., 2012). Examples of different communication privacy systems include use of SSL and TLS, off the record messaging and so on. SSL or secure socket layer protocol is a privacy enhancing technology in which the web browser by default encrypts all the web requests while undergoing a communication with an SSL web server. TLS is the later version of SSL, while its application is similar to SSL (Bhargavan et al., 2013). One of the most striking features of SSL is that, no human intervention is needed for encryption. Off record messaging on the other hand, is a technology to protect the contents of the instant messaging and communication over the internet. This PET system encrypts all the instant messages so that no third party can access the information. Off record is used by many communication applications such as iChat and Trillian. Apart from these, there are other different privacy enhancing techniques such as private payments and use of anti phishing tools further helps in protecting the privacy of data over internet. Answer 3 Wireless sensor network can be termed as a network of the spatially distributed devices that are interconnected with each other. It is used for providing a wireless connection to the different devices. Sensors are used to monitor the physical and environmental conditions of the sensors. WSN consists of different base stations and nodes or the wireless sensors. The different layers of WSN protocol stack include application layer, transport layer, network layer, data link layer and physical layer. The different types of threats on which the WSN network is exposed to are as follows- Spoofing Attack Spoofing is one of the common attacks in the wireless sensor networks. It makes use of a malicious program disguised as a legitimate program in order to gain an illegitimate advantage. This as a result can corrupt the network traffic extensively (Singla Sachdeva, 2013). Furthermore, continuous alteration in messages can result in loss of data packet during its transmission. Sybil Attack Sybil attack is another prominent attack in the wireless sensor network. There are cases where the sensors of a particular network might need to work together. In such cases, the entire task is distributed into a number of sub tasks (Venkatraman, Daniel Murugaboopathi, 2013). Presence of a malicious node in the network often tunnels the information or data to a complete different location. Network Flooding It is often seen that a malicious code present in a WSN can generate a large number of useless traffic thereby flooding the entire network. This causes congestion in the network leading to the exhaustion of the nodes. This attack is much similar to denial of service attacks. Apart from these, there are certain other threats and vulnerabilities in WSN. These include sinkhole attack, node replication attack, wormhole attack and so on. The threat mitigation techniques for these attack is discussed in the following section. Threat Mitigation The different thereat mitigation techniques that can be employed in order to ensure a safe operation of wireless sensor network are as follows- Only the authorized nodes are allowed to communicate over the network. The attack can be avoided by verifying the identity of the different nodes of a WSN by a trust worthy node. The flooding attack can be prevented by limiting the number of requests a node can handle in a set amount of time. Use of a proper intrusion detection system in the network can help in identifying the presence of malicious nodes (Alrajeh, Khan Shams, 2013). References Alrajeh, N. A., Khan, S., Shams, B. (2013).
