MA-DSR; Multi Agent based Adaptive DSR protocol with intelligent behavior in realistic environments

A mobile ad-hoc network (MANET) is a collection of wireless mobile nodes forming a temporary Network. These networks do not require any existing infrastructure or central administration. To make MANETs adaptive to different mobility and traffic patterns, this paper proposes a novel routing scheme which is utilized mobile agents and attempts to develop DSR routing protocol in MANETs with simple node-level management behavior resulting in overall system optimization. We develop a probabilistic multi-path 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 DSR, the simulation results testify that our new robust algorithm can be suitable in ad-hoc situations. We refer to the protocol as the multi agents based adaptive DSR (MA-DSR).
