Loop-Based Topology Maintenance in Wireless Sensor Networks

Clustering is recognized as an effective topology maintenance framework to provide better scalability for Wireless Sensor Networks. When loop structures are deployed to topology maintenance, it can provide better robustness and convenient route recovery, for the topology information is disseminated within a loop instead of a single node and the nature of the loop that there are two paths between each pair of nodes within a loop provides backup routes. In this paper, we propose a novel topology maintenance approach based on loop structures. The algorithm is a distributed, on-demand and configurable. It prefers a low-mobility network which is typically suitable for wireless sensor networks.
