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.

Key words: wireless sensor networks, trust model, clustering, energy consumption

摘要: 通过对无线传感器网络的信任模型和节点的能量消耗的研究,针对能量受限的无线传感器网络容易受到攻击的问题,提出了一种基于信任机制的分布式簇头选举优化算法。簇头的选举综合考虑了节点的信任度和节点的剩余能量两种因素。实验证明,该算法提高了网络安全性,延长了网络生存周期。并且信任模型中的校正机制体现了模型的健壮性。
