Performance Analysis of DSR Protocol under the Influence of RPGM Model in Mobile Ad-hoc Networks

In this paper, we have analyzed the performance of a Mobile Ad-hoc Network (MANET) using the Dynamic Source Routing (DSR) protocol with groups of nodes moving according to the Reference Point Group Mobility (RPGM) model. Four different random mobility models, Levy-Walk, Probabilistic Random Way point, Random Direction and Random Walk were selected for group leader´s mobility and the effects of changing communication load and transmission ranges were investigated. The results indicate that the performance of DSR is better if group leaders follow Levy-Walk mobility pattern regardless of load and range. The performance of DSR is worse if the leader´s mobility behaves like Rand-Dir or Rand Walk mobility models. This study concludes that the behaviour of leaders mobility may have significant impact on the network performance in MANETS.
