Simulation of an improved AODV algorithm for ad hoc network

Routing protocol is one of the most challenging problems in mobile ad hoc network. This paper proposes an improved routing protocol based on AODV for ad hoc network, which optimizes hello mechanism, local repair mechanism, and provides multi-backup pathways for the source node. Through network simulation, we show that new protocol can reduce network end-to-end delay, increase packet delivery ratio and balance network overload. Moreover, relative stability is another advantage of improved algorithm.
