Abstract: Existing Wireless Sensor Network(WSN) topology control algorithms are mostly based on ideal wireless environment, and it need node position information. This paper proposes a topology control algorithm based on path loss. It constructs topology through computing path loss of forward and backward paths with three or fewer hops from one node to another. Simulation result shows that this algorithm can reduce network energy consumption and the communication interference between the nodes, maintain the network connectivity, prolong the network life cycle.
