Investigating the impact of group mobility models over the on-demand routing protocol in MANETs

Due to the high mobility and frequently changing network topology, the choice of suitable mobility model and routing protocol has a significant impact on the performance of Ad-hoc networks, when deployed in unmanageable and hostile mobility environments. In this paper, the performance of various Group mobility models such as RPGM, Column, Nomadic and Pursue are evaluated and examined over the On-demand routing protocol (DSR) in the realistic scenarios using performance metrics like packet delivery ratio, average delay and normalized routing load. For the implementation, Linux (Fedora) Operating System is considered as a platform for the research work that is reliable and compatible with Network Simulator (NS-2) and the mobility scenario generation tool BENCHManet. The recommendations of the research will provide better understanding of the On-demand routing protocol, Mobility Models and their use in the real world applications such as rescue and relief operations, military operations, scanning and searching, tracking and surveillance operations and many more.
