Distributed Route Selection Algorithm in Nested Multihomed Mobile Networks

The present work is a distributed route selection algorithm in nested multihomed mobile networks. The mobile network node sends a request message to all leaf mobile routers inside the mobile network to initiate a session. All leaf mobile routers execute route selection algorithm to select the best route for the desired session of the mobile network node and send the best route to the mobile network node. The mobile network node transmits the packets corresponding to the desired session using the best route to Internet. The mobile routers associated with the best route execute egress interface selection algorithm to select the best egress interface and deliver the packets corresponding to the desired session of the mobile network node using the best egress interface to the next hop of the selected route. The performance of the proposed work is evaluated on the basis of throughput, session loss and route selection time using NEMO_SIM simulator. Results based on a detailed performance evaluation study are also presented to demonstrate the efficacy of the proposed scheme.
