Performance comparison of routing protocols for mobile ad hoc networks

Ad hoc networks are characterized by multi-hop wireless connectivity and frequently changing network topology which have made them infrastructureless. These networks need efficient routing protocols, so various ad hoc routing protocols have been proposed and compared based on some metrics. In this paper we present performance comparisons of the DSDV AODV DSR and TORA routing protocols with respect to a modified path optimality metric that we call it weighted path optimality, network's load deviation that affects nodes and can be a metric for load balancing, average end-to-end delay, and we analyzed jitter (average, maximum, and deviation) extensively, that recently became important in ad hoc networks. A variety of workload and scenarios which characterized by paused time are simulated with ns-2.
