In a MANET, mobile nodes must cooperate to dynamically establish routes using multi-hop wireless links. Some of the main challenges in this area related to routing protocols. 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 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 Agent based Adaptive DSR (MA-DSR). Finally, this paper proposes a new cross layer approach and some modifications in the MAC layer for RERR Analysis.. By this way, we can detect reason of RERR reception and apply proper mechanisms for performance improvement. We introduce yellow, red and black lists for decrease escaped, low energy, congested and insecure nodes chances in routing strategy. We expect that new condition aware MA-DSR, shows better performance.
