Clustering algorithm is usually adopted in wireless sensor networks（WSNs）for target tracking.A clustering algorithm based on nodes’degree was designed for high density WSNs.The algorithm introduced the concept of virtual node which was made up of nodes with similar degree.The nodes which made up of virtual node served as cluster head by turns according to the time slot distributed.The simulation experiment indicates the algorithm can effectively reduce the cluster’s renewal and extend the life of whole network at the premise of target tracking.
