摘　　要：为了解决智能电网中传感器网络节点能耗不均的问题,提出一种有效距离搜索的智能电网WSN多跳自适应路由算法。该算法首先引入距离矩阵重新计算普通传感器节点与其他路由节点的欧式距离,以此搜寻最小的有效距离;其次通过目标函数评估最优路径,以此实现自适应路由。仿真结果表明,该算法在发射功率严重不足时,仍能有效选择最优路径继续传输数据,且其传输性能明显优于LEACH协议、DEEC协议和基于蚁群的改进LEACH的路由算法,因此该算法具有较好的应用价值。In order to solve the problem of uneven energy consumption of sensor network nodes in smart grid,a multi-hop adaptive routing algorithm for smart grid WSN with effective distance search is proposed.Firstly the algorithm introduces the distance matrix to recalculate the Euclidean distance between the common sensor nodes and other routing nodes to search for the minimum effective distance.Secondly,the optimal path is evaluated by the objective function to achieve adaptive routing.The simulation results show that the proposed algorithm can effectively select the optimal path to continue to transmit data when the transmit power is seriously insufficient,and its transmission performance is better than LEACH protocol,DEEC protocol and ant colony-based improved LEACH routing algorithm,so it has a relatively good application value.
