In this paper, we present a Mobile Agents based Framework for Routing and Congestion control in Mobile Ad Hoc Networks (MAFRC). The framework uses a cross-layer design approach where multiple intelligent agents present across the network protocol stack cooperate with each other and aid in finding efficient routes between source and destination pairs and also in controlling congestion in the network. The mobile agents at the network layer moving across the network collect the network connectivity information based on the congestion state provided by the static agent at the link layer. The congestion information brought by these mobile agents is further used in controlling congestion at the transport layer. This multi-agent cross-layer framework has been implemented and a preliminary performance evaluation has been carried out for the congestion aware routing and the cross-layer congestion control scheme in a simulation environment using NS-2 simulator. The results show better performance with respect to the performance parameters such as network throughput, end-to-end delay and routing overhead when compared to the network architecture which uses Ad Hoc On-demand Distance Vector (AODV) as a standard routing protocol and Tahoe TCP.
