A mobile ad hoc network (MANET) is a network consisting of a set of wireless mobile nodes that communicate with each other without centralized control or established infrastructure. The mobility model should represent the realistic behavior of each mobile node in the MANET. Routing protocols for ad hoc networks are typically evaluated using simulation, since the deployment of ad hoc networks is still relatively rare. However, past evaluations of multicast routing protocols have utilized a single, simple random way point mobility model, and thus do not capture the variety of mobility patterns likely to be exhibited by ad hoc applications. In this paper, the results on the simulation study of the impact of different mobility models on multicast routing protocols are presented. The performance of on demand multicast routing protocol (ODMRP) and adhoc demand driven multicast routing (ADMR) protocol under different mobility scenario is evaluated. The results show that the throughput of ADMR is higher than of ODMRP at high mobility. This is achieved at the cost of increase in delay and transmission over head. Under low mobility, ODMRP has higher throughput than AMDR. Among the three mobility models considered, the throughput of ODMRP is the highest at low mobility. The results show that the protocols performances vary widely across the different mobility models.
