在基于簇结构的无线传感器网络中无线传输过程容易受到恶意节点攻击,其中簇头节点同时担任了管理控制簇成员、簇内数据收集及簇间数据转发等多重任务,因此簇头的选择尤为重要.充分考虑到网络的安全和能量问题,提出一种兼顾节点信任度、通信、能量及数据多因素的簇头选择算法,通过该算法可以准确地识别出网络中的恶意节点,并选取出可信度高的簇头节点.通过仿真实验证明该算法充分考虑到了综合因素,客观且准确地评价了节点,增强网络的安全性同时延长网络生存周期.

In wireless sensor network based on cluster structure,the wireless transmission is vulnerable and it will be attacked by malicious nodes.The cluster head nodes take multiple tasks,They served as the master of cluster nodes,and they also control the data collection within the cluster and the data forwarding between clusters,so the choosing of cluster head nodes is quite important.Fully considering the problem of energy and network security,a cluster head selection algorithm caring for the trust value of nodes,communication,energy and data was proposed in this paper.In this algorithm,the malicious nodes can be accurately identified in network,and the nodes with high credibility will be selected as the cluster head nodes.The simulation experiments show that the algorithm fully consider the combination of factors,and it can make accurate and objective evaluation about nodes.The algorithm enhance the security of network and prolong the life cycle of network.
