摘要：In a wireless sensor network which consists of a base station as a data sink and a number of sensornodes, the clustering has been adopted as a way of reducing the energy consumption of communication. The clustering,however, has suffered from the rapid burnout of cluster heads. We propose a 2-tier data collection architecture whichrequires single-hop intra-cluster transmission and direct communication between mobile sink and cluster heads. Tomaximize the network lifetime, cluster heads are reselected based on the remaining energy level. The clustering and therouting algorithm are processed by the base station and a mobile node navigates among sensor nodes periodically,collects power usage data from each sensor node, and deliver the next clustering and routing information. A clusteringand mobile sink navigation path search algorithm based on Voronoi graphs is proposed.
