Abstract: By studying the trust model and the node energy consumption of wireless sensor networks, against the problems that energy constrained wireless sensor networks are vulnerable to be attacked, a trust mechanism-based distributed cluster head election algorithm is proposed. The election of cluster head considering two factors, the trust of node and the residual energy of nodes. Experiments show that the algorithm increases network security, extends the network lifetime. And the correction mechanism in the trust model reflects the robustness of the model.
