摘　　要：无线传感器网络使用多跳通信的模式从感测区域中收集环境数据.为了延长网络的寿命,提出一种基于可信度的异构网络汇聚路由协议.利用节点的剩余能量、可信度以及节点与汇聚节点之间距离选择簇首.在可信度高于一定阈值的前提下,能量剩余高和距离基站较近的节点比能量剩余少和距离基站较远的节点拥有更多的机会成为簇首,模拟实验结果表明,该协议减少了网络中的能量消耗,延长了网络的生命周期.Wireless Sensor Networks collects environmental data from sensing area through multi-hop communication model. In order to prolong the network lifetime, A Trust-degree based Heterogeneous Networks Aggregation Routing protoeol（THNAR） is proposed. Cluster-heads are eleoted by residual energy of node, the distance between node and sink node, and node＇s trust degree. Under the premise of the condition that node trust degree is greater than or equal to some certain threshold value, the probability of nodes with more residual energy and closing to sink node who are selected as duster-heeds is larger than that of nodes with less residual energy and far from sink node. Simulation results show that the proposed protocol reduces energy consumption and prolongs network lifetime.
