Much more attention has been attracted in WSN (Wireless Sensor Network) recently. The problems of low energy consumption and high security of WSN are required to solve. In this paper, we propose a security mechanism based on LEACH routing protocol against Sybil attack. The mechanism is set to start up Sybil attack detection policy based on RSSI (Received signal strength indicator) when the cluster-heads number in WSN is over a threshold. We analyze mechanism performance of security and energy consumption through a series of experiments. As a result, it shows that the mechanism is effective and robust for resisting Sybil attack.
