Impact of Different Mobility Models on AODV Protocol in MANET with NS-2.35 and Bonnmotion-2.1a

Abstract: Mobile Adhoc Networks are self configuring,infrastructureless network (i.e) a network without any existing network infrstructure or centralized administrationn. To faclitate communication among the nodes in MANET, multiple hops are needed due to the limited range of wireless network interfaces. In order to exchange data among the nodes ,a routing protocol[1] is used to discover the routes. The goal of routing protocol is to efficiently construct a route between a pair of nodes with minimum routing overhead and bandwidth consumption. In this paper, the performance of the best mobility model with the use of AODV routing protocol is implemented. Link breaks and Average Link Changes are calculated for different mobility models like Random Walk,Gauss Markov,Manhattan using BONNMOTION 2.1a[5] by varying the Network Size,Simulation Time and Transmission Range in order to decide on the best mobility model . Further the correctness of the best mobility model is investigated by the assessment of performance paramaeters like packet delivery ratio (PDR), average end to end delay, and throughput. . NS-2.35[6] was used to produce the networks, services and situation personality. According to the simulation study,the best mobility model is manahattam mobility model with less number of link breaks and average link changes and also with the instigation of performance metrics.
