Topology-aided geographic routing protocol for wireless sensor networks

Conference Name:13th International Conference on Web-Age Information Management, WAIM 2012. Conference Address: Harbin, China. Time:August 18, 2012 - August 20, 2012.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. 漏 2012 Springer-Verlag
