Abstract

A Mobile Ad Hoc Network (MANET) is a network consisting of a set of mobile hosts capable of communicating with each other without the assistance of base stations. The dynamic topology of a mobile ad hoc network poses a real challenge in the design of a MANET routing protocol. Over the last 10 years, a variety of routing protocols have been developed and their performance simulations are made by network researchers. An efficient approach is to consider routing algorithms in which network connectivity is determined in the process of establishing routes. The shortest path (based on a given cost function) from a source to a destination in a static network is usually the optimal route, this idea is not easily extended to MANET. Factors such as power expended, variable wireless link quality, propagation path loss, fading, multi-user interference, and topological changes, become relevant issues. The network should be able to adaptively alter routing paths to alleviate any of these effects. Hence, Performance is an interesting issue for different protocols. This paper describes some special characteristics of ad hoc on-demand routing protocols like DSR, AODV, and TORA, with their working and performance measurements of these protocols.
