Mobile Ad Hoc network is a collection of mobile nodes that are arbitrarily located in such a manner that the interconnections between nodes are capable of dynamically changing on a continual basis. Reliable transport protocols such as TCP are tuned to perform well in traditional wired networks where packet losses occur mostly because of congestion. In wireless link packet losses (due to noise) are often more significant than congestion losses. Congestion avoidance results in a very low utilization of the link when there is an appreciable rate of losses due to link errors. This issue is very significant for wireless links.
