基于云安全模型的簇状树形无线传感器网络路由协议

由于传统的簇状树形无线传感器网络路由协议簇首能耗方差较大，导致存活节点数量和节点剩余能量较少，降低了无线传感器网络的使用寿命，为此设计一种基于云安全模型的簇状树形无线传感器网络路由协议。通过计算簇状树形无线传感器网络在接收与发送数据时的传输能耗，利用云安全模型获取云安全态势各种要素之间的不确定关系，预测节点的综合信任值，以预测结果为基础，采用蚁群算法获取分区节点的最优路径，完成簇状树形无线传感器网络路由协议。实验结果表明，本文设计的路由协议簇首能耗方差较小，存活节点数和节点剩余能量更多，接收数据包量比其他2种协议分别高出了48.1%和22.6%。由此可见，本文设计的路由协议延长了簇状树形无线传感器网络的使用寿命。

Routing Protocol of Cluster Tree Wireless Sensor Network Based on Cloud Security Model

Because of the large energy consumption variance of the cluster head of traditional cluster tree wireless sensor network routing protocol, the number of surviving nodes and the residual energy of the nodes are less, and the service life of the wireless sensor network is reduced. So a cluster tree wireless sensor network routing protocol based on cloud security model is designed. By calculating the transmission energy consumption of clustered tree wireless sensor network when receiving and sending data, the cloud security model is used to obtain the uncertain relationship between various elements of the cloud security situation, and the comprehensive trust value of nodes are predicted. Based on the predicted results, the ant colony algorithm is adopted to obtain the optimal path of the partition nodes, and the clustered tree-shaped wireless sensor network routing protocol is completed. The experimental results show that the designed routing protocol cluster head energy consumption variance is small, the number of surviving nodes and the remaining energy of the nodes are more, and the amount of received data packets is 48.1% and 22.6% higher than other 2 kinds of protocols respectively. It can be seen that the routing protocol designed by this paper extends the service life of clustered tree wireless sensor network.
