A topology control algorithm based on mutual selection mechanism is proposed, combined with complex network model. It adopts node strength and spacing between nodes as the measuring parameters, selects the cluster head nodes based on mutual selection mechanism in the communication radius of nodes and builds the hierarchical topology. The algorithm can improve the clustering efficiency, shorten the average path length and save the energy of the nodes. The simulation and analysis of network
