A comprehensive view of mobility models in Wireless Ad hoc Networks
نویسنده
چکیده
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

Mobile Ad hoc networks (MANETs) are composed of mobile stations communicating through wireless links, without any fixed backbone support. In these networks, limited power energy supply, and frequent topology changes caused by node mobility, makes their routing a challenging problem. TORA is one of the routing protocols that successfully copes with the nodes’ mobility side effects, but it do...
