Topology-aided geographic routing protocol for wireless sensor networks

Abstract

The problem of the traditional geographic routing protocols for the wireless sensor networks is that they can only adopt one kind of strategy, such as the right-hand rule, to bypass a hole, which is not always a proper choice. In this paper, we propose a topology-aided geographic routing protocol, which utilizes the topology of the network to guide a packet bypassing a hole in a shorter path than that of the traditional protocol. Experimental results show that our topology-aided geographic routing protocol can reduce the length of the path from the source to the destination. © 2012 Springer-Verlag.
