Impact of mobility on the performance of mobile ad hoc networks

Abstract

In ad hoc networks, the mobility of nodes affects the system performance. Considerable attention has been paid to mobility models. However, most work is confined to simulation. A novel method is proposed to analyze the performance of mobile ad hoc networks (MANETs) considering the node's mobility. In the proposed method, of each communicating pair, one is considered to be stationary while the second is moving with a velocity relative to the first one. Using this method, system performance parameters, such as the average radio range dwell time of mobile nodes, link holding time, link breaking probability, and throughput of CSMA/CA protocols, are obtained by a theoretical framework. The results obtained from the proposed analytical model are observed to match well with simulation results.
