Adaptive DSR Protocol with Cooperative Agents for Different Mobility and Traffic Patterns

Abstract

The autonomous character of mobile ad-hoc networks (MANET) poses significant challenges on network communications. Some of the main challenges in this area related to routing protocols. To make MANETs adaptive to different mobility and traffic patterns, this paper proposes a novel routing scheme which is utilized cross layer design and attempts to develop DSR routing protocol in MANETs with simple node-level management behavior resulting in overall system optimization. We develop a probabilistic multipath routing algorithm and incorporates factors like signal strength into the route metrics so as to predict link breaks before they actually occur. In addition to signal strength and shortest-path metrics, our algorithm updates the goodness of choosing a particular path based on congestion measurement and energy level in each node. By All of the above improvements in conventional DSR, the simulation results testify that our new Robust DSR algorithm can be suitable in ad-hoc situations.
