摘要：Mobile Ad Hoc network (MANET) is a collection of smart mobile nodes, which form a dynamic and autonomous system. Since mobile nodes are free to move, they cause frequent changes in network topology and decrease the overall network performances. Therefore, the task of finding and maintaining a reliable route constitute the main issue in the design of efficient routing protocol for MANET. In this paper, we introduce a novel Mobility Adaptive AODV routing protocol (MA-AODV), which uses the degree of mobility time variation and the local route repair approach to mitigate the influence of high mobility and improve routing performances. We implemented the MA-AODV on network simulator NS2. Then, we evaluated the performance of MA-AODV and AODV based on node mobility variation such as speed and pause time. The comparison of performance metrics, such as Packet delivery Ratio, Throughput, routing overhead and communication delay demonstrates that MA-AODV outperforms AODV in high mobility environments.
