BPR: A Bearing based Passive Routing for Mobile Ad hoc Network

Some conventional routing protocols for mobile ad hoc network (MANET), such as AODV, are not scalable because of excessive protocol overhead. We propose bearing based passive routing (BPR) which introduces geographic information into AODV. BPR takes advantages of both AODV and geo-based protocols so that it not only finds the shortest route, but also reduces the overhead of route construction. We validate BPR´s feasibility through simulations, and compare it with AODV to demonstrate it is better on the metrics of delivery ratio and protocol overhead.
