Performance comparison and analysis of ad hoc routing algorithms

A mobile ad-hoc network (Manet) is a system of wireless mobile nodes dynamically self-organizing in arbitrary and temporary network topologies. People and vehicles can thus be internetworked in areas without a pre-existing communication infrastructure, or when the use of such infrastructure requires wireless extension. Therefore, such networks are designed to operate in widely varying environments, from military networks to low-power sensor networks and other embedded systems. Frequent topology changes caused by node mobility make routing in ad hoc wireless networks a challenging problem. We focus upon routing protocols for ad hoc networks. We study and compare the performance of several routing protocols. A variety of workload and scenarios using a variety of mobility, load and size of the ad hoc network were simulated.
