Abstract
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.
