Security Issues in MANETs Abhishek Seth 04329001 November12 ,2004

Mobile Ad hoc Networks (MANET) has become an exciting and important technology in recent years because of the rapid proliferation of wireless devices. A mobile adhoc network consists of mobile nodes that can move freely in an open environment. Communicating nodes in a Mobile Adhoc Network usually seek the help of other intermediate nodes to establish communication channels. In such an environment, malicious intermediate nodes can be a threat to the security of conversation between mobile nodes. The security experience from the Wired Network world is of little use in Wireless Mobile Ad hoc networks, due to some basic differences between the two Networks. Therefore, some novel solutions are required to make Mobile Adhoc Network secure.

problems of secuirity in MANETs. Further sections deals with some of the solutions to these problems. Finally Section 10 concludes this article.


Mobile Adhoc Networks



Mobile Adhoc Network (MANET) is a collection of independent mobile nodes that can communicate to each other via radio waves. The mobile nodes that are in radio range of each other can directly communicate, whereas others needs the aid of intermediate nodes to route their packets. These networks are fully distributed, and can work at any place without the help of any infrastructure. This property makes these networks highly flexible and robost. The characteristics of these networks are summarized as follows:

• Communication via wireless means. A Mobile Adhoc Network is a group of wireless mobile computers in which nodes cooperate by forwarding • Nodes can perform the roles of both hosts and packets for each other to allow them to communicate routers. beyond direct wireless transmission range. Application • No centralized…...

Socratic Seminar

...was short and ugly and only possessed life’s necessities. This shows that he didn’t want people to look at him for his possessions or looks; he just wanted people to notice his teachings. Socrates inspires me to be determined and to look deeper into questions. I think that Socratic Seminars will be a great learning tool for our class. A Socratic Seminar is an organized debate that allows everyone to voice their opinions without intense conflict. I think that this will be good for our class because I like to hear what other classmates think about passages, and stories that we read in class. I think that this will be good because we will be able to form new opinions based on our classmate’s thoughts and feedback. These Seminars are also good because there really isn’t “right” answer, so we can get into deep discussions without worrying about what we say is right or wrong. For example, our values essay that we have been writing feature things that we value in our lives. Some things that I value in my life, others may not. So if we reviewed our essays in a Socratic Seminar, we could go on for hours about our opinions of our different values. I am looking forward to participating in these Socratic Seminars....

...HW205: Vitamins, Herbs and Nutritional Supplements Seminar Option 2 1.) Define the differences between the following terms: a) Natural Medicine vs. Biomedicine Natural Medicine is considered alternative medicine, which is any medical therapy that is not a synthetic drug or surgery.

Hiv Seminar

...After attending the seminar on HIV in the Grand Ball Room tonight, I learned some new things about HIV that I did not know. The speakers did an awesome job explaining HIV and how it is not a death sentence, but rather just an illness/disease that can be treated and not cured. They spoke about once you contract the disease that you need to go and be treated as soon as possible to help increase your life expectancy. The only way that HIV is a death sentence is when it is left untreated. They told stories about some of the clients that have come in and was tested, names were left out, and the results of the test. The seventeen year old boy is very lucky and hopefully learned what could of happened so he can help prevent it. After the teenager went up north and had some unsafe fun with another male partner about ten years older than he was the boy is very luck not to of contracted the HIV disease because come to find out the partner from up north was positive for it and maybe this scare may have made the boy aware of what could have happened. I learned that African American males say they use condoms, but according to the statistics of HIV, they do not because they are one of the highest rates. If everyone would practice safer sex, we can get the number of new cases down to zero and that has been and will be the theme of the World Aids Day for the next couple of years. Relationships are not monogamous anymore due to partners heating on each other and giving STD’s and STI’s to......

...Darrellynn Tapp HS210-MOM Unit 9 Seminar option 2 K. Drennen Kaplan University What are some effective ways to improve employee morale? When improving employee morale it first starts with the employee. Recognizing the value of your employee is very important. You must know that they are just as important as you are. They can be replaced but then you are dealing with the cost of advertising and pulling in someone new. Letting the employee know that they are appreciated. Just a simple few words such as thanks or a job well done will help increase the morale among employees. Giving out perks, sponser social events, have special lunches as well as cash bonuses, even pinics for the employees and their families. Having a great work environment can improve employee morale. A dull office setting lacking light and color can cause depression and the lack of motivation. Putting some spark into the office can lighten up employees spirit. Make sure the values and ethics of the company are of those employees can take pride in. Most employees in the work force want to work for a company they can trust and believe in. Be loyal to your employees. If business starts to decline, find ways to keep employees without cut backs or lay offs. Be sure to offer promotions and pay raises to those who deserve it.

Socratic Seminar

...Socratic Seminar Reflection Before the seminar, I liked the text The Scariest Thing I Know. I liked it since the text was descriptive and interesting to read, I also thought that there was a lot of hidden metaphor in the story which was interesting to decipher. My thoughts immediately after reading the text were that Kid Death was really a metaphor for Nick who had always hid behind a mask to appear frightening and cool but once you “took off his mask.” He was just another Geek like Kid Death. I also thought that the Angel must also be a metaphor for something, and I realized that it was a metaphor for the angel that had saved Nick. I thought that Kid Death and the Angel bundled together represented what we perceive as the “Devil and Angel on our shoulders.” The Devil is Kid Death and the angel being the angel. This showed nicks inner battle to either remain behind a mask and be cool like Kid Death and make Bad things happen. Or be good like the angel and not be so cool but still be good, in the end he chose the path of the Angel and this changed his life since he started being good and not always acting tough since he knew what happens if he does. Before the seminar, I had a pretty clear idea of what the subject of the story was. I remembered the general area of the subject of the story was to constantly travel the good path in life. In the scene near the end of the text where Nick was “frozen in time” and was looking at the angel saving his brother. He could......

...Running head: SEMINAR ALTERNATIVE ASSIGNMENT – UNIT 1 Seminar Alternative Assignment – Unit 1 Kaplan University MT302: Organizational Behavior SEMINAR ALTERNATIVE ASSIGNMENT – UNIT 1 1 What do managers do? “Managers get things done through other people,” (Robbins & Judge, pg. 5). This might seem like an extremely simple definition of a manager’s responsibilities, but it is the truth. There are many methods and ways in which a manager can develop their administrative and people skills. By using systematic study, utilizing the POLC and organizational behavior (OB) models, defining management roles, understanding OB challenges and opportunities, and assessing management skills and managerial activities, a manager can empower and motivate their employees, stimulate innovation, and improve customer service, while creating a healthy work environment. What is organizational behavior? Organizational Behavior is a “field of study that investigates the impact that individuals, groups, and structure have on behavior within organizations, for the purpose of applying such knowledge toward improving an organization’s effectiveness.” In other words, it is “the study of what people do in an organization and how their behavior affects the organization’s performance,” (Robbins & Judge, pg. 10). There are different tools that managers can use to better achieve their goals. One of these tools is called the POLC model. The POLC model consists......

...Seminar is a play by Theresa Rebeck that premiered on Broadway in 2011. It follows four aspiring writers who pay for a supposed great writer – Leonard – to come and critique their writing weekly. Each writer is their own personality. There is the rich, uppity, nerd-type (Kate), the quieter, reserved, and talented one (Martin), the ditzy, manipulative, and sexy one (Izzy), and the extravagant, smart, and connected one (Douglas). Leonard is depicted as brash, rude, cruel, and unpardonable. The story goes on to where Martin and Leonard connect and see their similarities and work together to better themselves. A theme that immediately jumps at you is conflict. Throughout the play, there is conflict every other conversation. High tension exists between most characters, especially between those of different sexes. Examples are Kate and Leonard throughout most of the play and Martin and Douglas (though one-sided) in scene one, two, and so on. Another theme that is prevalent is the idea that sex sells and that sex will get you everywhere you want to be. This is shown when Izzy writes a story that Leonard deems sexy, and they proceed to pursue a sexual relationship. It could also be interpreted that sexism could be a theme when sex is not available. When Kate submits a story, being defined as a “prude,” Leonard is bored before ending the first sentence, and is bored with her immediately every time following. That is, until she submits something under the guise of a transvestite...

Seminar Paper

...A.Sri Dithya ChemE5870: Energy Seminar I Net id:sa929 The speaker, Lars Angenent gave us a brief detail about biotechnology with microbiomes for biochemical production,including fuels from biomass.In the seminar the speaker discussed about environmental biotechnology like the anaerobic digestion,Syngas fermentation and microbial electrochemistry.The speaker was successful in keeping the audience involved.The presentation started with brief explanation of environmental biotechnology wherein various processes like anaerobic digestion were explained.Anaerobic digestion is a series of biological processes in which microorganisms break down biodegradable material in the absence of oxygen. Other few processes which were discussed in the presentation include microbial electrochemistry which is the study and application of interactions between living microbial cells and electrodes,Syngas fermentation where a mixture of hydrogen,carbon monoxide and carbon dioxide known as syngas is used as carbon and energy sources and then converted into fuel and chemical by microorganisms.Main takeaway from these processes would be that open culture,that is ,reactor microbiomes can produce biochemicals at high selectivities and rates(besides methane).One of the applications of this process is biorefinery platforms which involves hydrolysis and intermediate steps.Few of the examples being the sugar platform,syngas platform and carboxylate platform which involves primary and......

...Unit 3: Seminar Assignment MT480-01: Corporate Finance Alicia Turner Kaplan University Professor: S. Lacewell January 21, 2012 Seminar Assignment Unit 3 1.) What effects do changing interest rates have on bonds? The effects of changing interest rates on bonds would be the bond prices. If the interest rates tend to increase then the bond value will go lower and if the interest decreases then the bond value would be higher. In a case of purchasing a bond, the bond starts off with a fixed rate until it starts to mature. For example, if i were to purchase a bond at $5,000 with a 5% rate for 10 years, if the interest goes up to 6% then the value of the bond that I purchased would decrease and it would be beneficial for me to sell that bond at a discounted price. 2.) How are stocks prices related to expected dividends? Stock prices are related to expected dividends due the return that a person would receive on their stock. If the stock prices increase then your return would also increase. If the stock decreases then the expected dividend would remain the same as when the stock was purchased. 3.) How does the P/E ratio relate to the value of a stock? The P/E ratio is related to the value of stock due to the fact that it lets an investor/buyer know how much they are willing to pay per dollar of earnings. For instance, if a P/E ratio is 40 it would tell us that an investor is willing to pay $40 for every $1 of earnings that is generated by that......
