摘要：Mobile ad-hoc networks (MANET) are collections of wireless mobile nodes dynamically forming a temporary network without the use of any pre-defined network infrastructure or centralized administration. In this paper, performance evaluation of both proactive wireless routing protocol destination sequenced distance vector (DSDV) and reactive protocols ad-hoc on demand distance vector(AODV) with continuous bit rate (CBR) traffic is executed using NS-2 simulator. The research work mainly focuses on the protocols behaviour on different mobility. The performance differentials are analyzed with varying network load and mobility. Random waypoint model is used to create mobility model for this research work. Two types of simulation work on mobility are done under same simulation environment, which make it more closely to evaluate the performance of routing protocols. In total five performance metrics are measured to conclude this paper. It demonstrates that even though both protocols share distance vector characteristics, the individuality of protocol’s mechanism draw considerable performance differentials with mobility. Finally, according to results of practical works, we can clearly say that the routing protocols AODV gives less fluctuation results and better performance as compare with DSDV, with respect to some identified parameters of routing protocol such as , routing over head, throughput and average end- to- end delay.
