For the WSN disconnections caused by some invalid nodes,this paper proposes a connection strategy based on clustering and path planning and suitable for command monitoring.Cluster heads in the optimal number are selected by weight competition,while the rest static nodes are clustered on signal intensity of cluster heads.Meanwhile,the mobile node moves among all cluster heads and sink as soon as possible according to the mathematical model of DTSP.Both them cooperatively maintain,the network connectivity.Simulation results reveal that the clustering algorithm for static nodes could remarkably raise the rounds,and the path planning for mobile nodes reduce the data-loss rate.
