Abstract
The highly dynamic topology changes caused by quick and random node mobility make the existing wired routing protocol unsuitable for mobile ad-hoc network (MANET). AODV protocol is proposed for this highly mobile network, but AODV only saves the least hops path to the destination. When the link breaks, it needs to rediscover the route that increase network overload. In this paper, we devise the conventional AODV and propose a new modified AODV routing protocol called MAODV which takes route stability into consideration to attempt to establish a more stable path between the source and destination. In MAODV, we make some changes in Hello and RREQ message format to respectively record the sending time and route stability factor. We use network simulator-2.30 to simulate both the AODV and MAODV protocols in the similar scenario. Simulation results comparison and analysis are made to evaluate the effectiveness of the MAODV and we find that the MAODV shows a better performance in some ways.
