Intelligent Agents for source decision making process in MANET

In this paper, we propose a new intelligent agent based multipath routing protocol for ad hoc wireless networks, which is based on the DSR (dynamic source routing)-on demand routing protocol. Congestion is the main reason for packet loss in mobile ad hoc networks. If the workload is distributed among the nodes in the system, based on the congestion of the paths, the average execution time can be minimized and the lifetime of the nodes can be maximized. We propose a scheme to distribute load between multiple paths according to the congestion status of the path. This protocol uses intelligent agent to obtain the congestion status of the nodes. Our simulation results confirm that the proposed protocol-IASR improves the throughput and reduces the number of collisions in the network.
