Routing path restitution approach to control and tolerate the congestion in routing models for mobile ad hoc networks is proposed in this paper. Packet loss in network routing is primarily due to link failure and congestion. The majority of present congestion control solutions do not possess the ability to distinguish between packet loss due to link failure and packet loss due to congestion. Here in this paper we propose route discovery and congestion handling algorithms. The proposed cross layer model includes network, MAC and transport layers. In the proposed model the MAC and network layers are having active role in congestion detection and regularization, in contrast the network and transport layers are active in congestion endurance. The experimental and simulation results show that a better congestion control and endurance is possible for this protocol.
