Robust Geographic Routing with Virtual Destination Based Void Handling for MANETs

Traditional MANET routing protocols are quite susceptible to nodes´ mobility, especially for large-scale networks in which the end-to-end path length is usually large. In order to improve the routing performance in the face of fast changing network topology, we propose a novel Robust Geographic Routing (RGR) protocol which takes advantage of the broadcast nature of wireless medium by employing opportunistic routing like forwarding strategy. At the same time, a Virtual Destination based Void Handling (VDVH) scheme is also proposed to work together with RGR. Simulation results show that RGR achieves excellent performance even under high node mobility and the new void handling scheme also works well and further enhances the performance of RGR.
