Efficient on-demand routing for mobile ad-hoc wireless access networks

In this paper, we consider a mobile ad-hoc wireless access network in which mobile nodes can access the Internet via a stationary gateway node or access point. Mobile nodes that are outside the transmission range of the gateway can continue to communicate with the gateway via a multi-hop connection with their neighboring nodes. The ad-hoc on-demand distance vector (AODV) routing protocol is extended by incorporating the concept of load-balancing (LB). We call this the LB-AODV routing protocol. Simulation results show that in a congested network environment, our proposed LB-AODV has a higher packet delivery fraction, a lower end-to-end delay and control overhead when compared with both AODV and gossip-based routing protocols.
