【 摘 要 】

Establishing and maintaining link stability in Mobile Ad hoc Networks (MANETs) is one of the key challengingissues. Topology changes in MANET because overhead traffic that leads to consuming extra energy of nodes as well asdecreasing the performance of routing protocols. Thus, a comprise approach should be considered during the design of arouting scheme in MANETs to deal with challenges incurred by the mobility of the nodes. In this study, a simple efficientrouting scheme called Enhanced_AODV (E-AODV) is proposed, aiming to enhance Ad Hoc On-Demand Distance Vector(AODV) routing protocol performance by constructing the most stable and reliable route from source to the destination node.In this routing scheme, the remaining lifetime of links and hop count are the metrics considered for calculating the RouteStability Factor (RSF) that can be utilized as a cost metric to establish the best route between source and destination node. Thesimulation results reveal that the proposed E-AODV routing scheme effectively outperforms the conventional AODV routingprotocol and Stable and Bandwidth Aware Dynamic Routing Protocol (SBADR) in terms of packet delivery ratio, averagenetwork throughput, average end-to-end delay, and normalized routing overhead.
