MA-AODV: Mobility Aware Routing Protocols for Mobile Ad Hoc Networks

A mobile ad hoc network (MANET) is a collection of mobile nodes that communicate and collaborate with each other without reliance on any pre-existing infrastructure. In MANETs, wireless links are subject to frequent breakages due to nodes high mobility. While several routing protocols such AODV and DSR have been designed for MANETs, many of operate efficiently under low network mobility conditions and do not adapt well with high mobility conditions. Therefore, considering mobility is a demanding task that should be performed efficiently and accurately. In this paper, we propose novel mobility-aware routing protocols based on the well known ad hoc on demand distance vector (AODV) routing protocol called: MA-AODV (mobility aware-ad hoc on demand distance vector) in an attempt to improve the handling of high mobility in ad hoc networks. MA-AODV protocols perform periodic quantification of nodes mobility for the sake of establishing more stable paths between source/destination pairs, hence, avoiding the frequent link breakages associated with using unstable paths that contain high mobile nodes. Simulations are done using GloMoSim 2.03 simulator. According to the results, our proposed protocols prove their superiority over the original AODV protocol in terms of the reduced overhead and the increased packet delivery ratio.
