Abstract: Mobile ad hoc network (MANET) plays a major role in enabling data communication in infrastructures-less areas. Network performance relies on the capacity of mobile nodes to process data packet and deliver it to the right destination at lower cost. Since nodes are free to move toward random destination, data delivery from a source to a destination might be disturbed due to frequent topology changes. Hence, mobility in mobile ad hoc network represents the main issue that should be addressed carefully while designing routing protocols. The purpose of this paper is to study the impact of node mobility on the performance of well-known routing protocols such as destination-sequenced distance vector (DSDV), dynamic source routing (DSR) and ad-hoc on demand distance vector (AODV). We assessed the efficiency of each protocol under high mobility environment using various values of speed and pause. Performance assessment is based on the conventional metrics such as latency, throughput, packet delivery ratio (PDR) and routing overhead. Moreover, we introduced two new metrics called path change factor (PCF) and route repair influence (RRI) for accuracy purpose. The study demonstrates that AODV has better performances in high mobility environment.
