A comprehensive view of mobility models in Wireless Ad hoc Networks

A Mobile Ad hoc Network (MANET) is a collection of wireless mobile nodes forming a selfconfiguring network without using any existing infrastructure. Since MANETs are not currently deployed on a large scale, research in this area is mostly simulation based. Among other simulation parameters, the mobility model plays a very important role in determining the protocol performance in MANET. Thus, it is essential to study and analyze various mobility models and their effect on MANET protocols. In this paper, the survey and examine different mobility models is proposed. Beside the commonly used Random Waypoint model and its variants, it is also discussed various models that exhibit the characteristics of temporal dependency, spatial dependency and geographic constraint. Here a comprehensive view of the mobility can significantly affect the protocol performance. Keywords— Mobility model; Mobile Ad hoc Network; Random Waypoint Model
