Mobile ad-hoc network is a collection of wireless mobile hosts forming a temporary network without the aid of any stand-alone infrastructure or centralized administration. Mobile ad-hoc networks have the attributes such as wireless connection, continuously changing topology, distributed operation and ease of deployment. In this paper the authors have compared the performance of two reactive MANET routing protocols AODV and DSR by using Group mobility model. Both share similar on-demand behavior, but the protocols' internal mechanism leads to significant performance difference. They have analyzed the performance of protocols by varying network load, mobility and type of traffic (CBR and TCP). Group Mobility model has been generated by IMPORTANT (Impact of Mobility Patterns on Routing in Ad-hoc NeTwork) tool.
