Connected devices have become a trend, with every devices from your home to your vehicle forming a highly connected environment. Internet of Things (IoT) [1] is a newly coined term allowing any device to form a network. The process becomes a bit complex when the nodes are in constant motion called MANETs [2], such a network will have nodes coming in and leaving in a short time. This requires a routing protocol that can find a path from source to destination with links that will exist till at least the final transmission [3][[4].
Another factor that comes into play is the heterogeneity of these nodes [5] as nodes forming the network can vary in energy levels, total range [6] and more. Here we focus on the interference, a high power node can cause compared to others and performance advantage of avoiding such nodes. Nodes with larger range are usually high energy and hence energy savings is an added advantage.
The attraction of [1] to consumers can fade away if the communication capability is not stable i.e., the links between nodes may disappear anytime. The work done by[5] Clusters the nodes with high power node as the head in a very loose coupled manner, this method while solving the negative effects of the heterogeneity. The arrangement utilizes the heads only while finding the route between two nodes and avoids it during the actual transmission. We propose a new 802.11 MAC protocol which considers power heterogeneity but at the same time considers the probable link duration while finding the final route.
Our paper tries to combine existing work to find out links between nodes that have a higher lifetime [4] with a routing protocol that avoids high power nodes [5]. We propose a routing protocol power and link aware routing...

Performance Enhancement Is Essential For Athletes Essay

- When it comes to participating in sports, there is a certain level of risk that coaches go through. They are responsible for the aspects of their athletic program. It is vital that coaches build a positive relationship with their athletes. As an athlete, it is important to understand the importance of training their body both mentally and physically in order to produce outstanding peak performances. When it comes to nutrition, an athlete who does not consume the proper amount of nutrition when it comes to training, the results may be suboptimal because of the reduced ability to perform due to useless energy and lack of recovery....   [tags: Nutrition, Food, Metabolism, Softball]

The History of Performance Enhancement Essay example

- PEDS – Performance Enhancement Drugs The history of performance enhancement follows a timeline as vastly embedded in our history as the sports themselves. These taboo substances are of the most absolutely misunderstood category in modern medicine, and will remain as such until the cloudy illusion filled veil enveloping them is torn down. The use of performance enhancing “substances/drugs ” for sporting spurs back as far the ancient Greek competitions of old, where contestants often chewed cocoa leaves or a utterly vast array of other “potions/concoctions”....   [tags: sports, drugs, steroids]

Stable and Self Adaptive Routing for Mobile and Ad Hoc Networks Using Cross Layer Design

- ... CL-DSR proposes the link metric as the link instability index denoted by ‘ψ’ as the cumulative value of the average bit error rate and their path loss computed from received signal strength. The computation of average bit error rate is given by [12.Justus Ch. Fricke,, 2007]. A multihop route consists of ‘n’ number of nodes connected by ‘n-1’ number of links. The link stability index of link ‘m’ between the intermediate node Ni-1 and Ni is represented as Where is the average Bit error probability of link ‘m’ and is the path loss incurred when receiving the RREQ at the node ‘i’ from the source node....   [tags: routing algorithms]

Offering Anomymity Protection with Anonymous Location-based Efficient Routing Protocol

- ... Anonymous routing protocols are crucial in MANETs to provide secure communications by hiding node identities and preventing traffic analysis attacks from outside observers. Anonymity in MANETs includes identity and location anonymity of data sources (i.e., senders) and destinations (i.e., recipients), as well as route anonymity. “Identity and location anonymity of sources and destinations” means it is hard if possible for other nodes to obtain the real identities and exact locations of the sources and destinations....   [tags: broadcast, routing, manet]

Performance Enhancement through Protein Supplementation Essay

- Introduction Scientists, coaches, and athletes have recognized that periodized strength training promotes increase in skeletal muscle size, increase in force, and increase of the regenerating capacity of the muscle cells. Innumerous scientists confirm that nutrition and dietary supplementation can deeply affect molecular and cellular processes that occur in the body during the exercise and the recovery process. This brief review analyzes the potential for performance enhancement through protein supplementation ingestion, and the importance of nutrition education for sports supplement users....   [tags: Weight Training, Nutrition, Dietary Supplements]

Essay on Genetic Engineering And Genetic Enhancement

- Genetic engineering versus genetic enhancement When it comes to the topic of genetic enhancement versus genetic engineering there is a debate whether which of these theories should be pursued, whereas some are convinced that genetic enhancement could help future generations in becoming smarter, faster and taller others maintain that genetic engineering can make future generations healthier. My own view however is that genetic engineering would help cure disesase and should be pursued, but genetic enhancement should not be allowed....   [tags: DNA, Gene, Human enhancement, Genetics]

Human Performance Enhancement Technology Essay

- Human Performance Enhancement Technology One of the funniest things about human nature is that nothing is ever good enough. No matter how good we are at something, there will always be someone in those 6 billion plus who can do it better. My mom told me that when I was a kid playing soccer in the back yard. They don't sound like the words of encouragement you might expect from a nurturing mother to an aspiring child but it was true. No matter how long I practiced, how many goals I scored, games I won, trophies I put on the shelf of my bedroom, there would always be someone, somewhere who could do me one up....   [tags: Science Engineering Essays]

Essay about The Routing Information Protocol ( RIP )

- The Routing Information Protocol ( RIP ) INTRODUCTION: I will summarize Request For Comments (RFC) 1058, Routing Information Protocol (RIP), by discussing RIPs basic algorithm/distance vector algorithm, protocol, message format, protocol limitations, and new improvements to RIP. RIP is very important to internetworking, since it passes information about routes between networks and hosts. It allows hosts and gateways to exchange information for the purpose of computing routes. BASIC ALGORITHM/DISTANCE VECTOR ALGORITHM: RIP was designed to work with moderate sized networks, which used pretty much the same technology....   [tags: Routing Information Protocol RIP Essays]

From the Bigs to NU: Performance Enhancement Essay

- From the Bigs to NU: Performance Enhancement From the very first time he touched the newest and hottest in a long line of drug fads, Justin Hedrick, then high school running back, now star pitcher for the Northeastern baseball team, was swept up in the craze of ephedra. Looking back, he realizes what a fortunate decision he made to stop using the common muscle supplement linked to as many as 155 deaths around the country since its introduction in the mid-1990s. “Before (football) season, we used to cut down a little bit of weight in order to see how fast we could run or get our 40 times up a bit,” he said....   [tags: Journalism Essays]

Artificial Olfactory Enhancement Essay examples

- Artificial Olfactory Enhancement The human olfactory system is responsible for perceiving the chemical world around us. By sampling the environment, we can determine the presence of other individuals, possible danger, or distinguish acceptable food. Consisting of our sense of taste and smell, the olfactory system is a highly interrelated coordination of chemical and nerve responses. Yet as we have all experienced, human olfaction has limits. The popular image of a bloodhound leading hunters through the woods is one example of these limits....   [tags: Olfactory Enhancement Essays]
