Analyzing Optimal Setting Of Reference Point Group Mobility Model Using DSR Protocol In MANETS

Abstract

Mobile Ad-hoc Network (MANET) is a self-configuring wireless network. The nodes can configure themselves to be in any arbitrary topology. It is essential that mobility models used in simulating different scenarios must emulate closely the real scenario in order to assess the MANET performance as accurately as possible. In this paper, the authors have studied the effect of different maximum pause times and maximum node speeds on different performance metrics in order to arrive at optimal settings for these two attributes under the Reference Point Group Mobility model for the DSR protocol. In addition, this work is part of an ongoing research on link failures in DSR protocol. Thus, the performance of the DSR protocol under the Reference Point Group Mobility (RPGM) model in terms of different pause times, node speeds, number of nodes and number of source connections were evaluated. The simulation results show that the maximum pause time and the maximum speed have direct impacts on the performance parameters such as packet delivery ratio, routing overhead, average end-to-end delay, normalized routing load and packet drop under the Reference Point Group Mobility model.
