A Reliable WSN Routing Algorithm for Detecting Distribution Network Fault

为了提高配电网故障检测数据传输的可信性,提出一种面向配电网故障检测的WSN可信路由算法。算法提出一种防范针对信任模型攻击的轻量级信任值计算方法,并在簇头选举与簇间多跳路由中引入信任值,避免恶意节点降低网络安全;簇间多跳阶段中,对邻居节点的位置因子、距离因子、信任值及剩余能量等参数进行融合判决,构建最优数据传输路径。仿真结果表明,提出的算法能够自适应剔除网络恶意节点,防范恶意攻击,最大化网络生存时间。

In order to meet the reliability requirements of wireless sensor network applied to distribution network fault detection,a Reliable WSN routing algorithm for Detecting Distribution network Fault（RDDF）was proposed. The algorithm presented a new lightweight trust value calculation method to prevent attacks on trust model. During the multi-hop between clusters and the election of cluster heads,the trust value was introduced to avoid malicious nodes affecting network reliability. According to the location factor,distance factor,trust value and residual energy of cluster nodes,the algorithm can choose the most appropriate forwarding cluster nodes to optimize the routing in the stage of multiple hops between clusters. The simulation results show that the algorithm could effectively eliminate malicious nodes,prevent malicious attacks and prolong the network life time at the same time.
