摘　　要：降低无线传感器节点能耗是当下拓扑算法研究的重点。通过对功率控制型算法进行研究后发现,现有算法忽略多跳中继区域问题,从而增加节点的能耗。因此提出面向低功耗的智能拓扑控制算法,该算法通过收集各节点功耗反馈信息后形成最大邻近节点拓扑,遍历所有邻近节点后选择能量消耗最小的路径。对网络连通性、节点度和能量消耗等性能指标仿真分析,算法能够消除不合理的多跳,降低每个节点的最大发射功率,维护全网络的连通性,理论上具有一定的实际应用价值。Reducing the energy consumption of wireless sensor nodes is the focus of intelligent algorithm research.This paper studies the power control algorithm and finds that the existing algorithm ignores the problem of multi-hop relay area,which increases the energy consumption of nodes.Therefore,this paper proposes a low-power intelligent topology control algorithm.The algorithm collects the feedback information of each node′s power consumption,forms the topology of the largest neighboring node,traverses all neighboring nodes,and selects the path with the least energy consumption.The algorithm can eliminate unreasonable multi-hop,reduce the maximum transmission power of each node,and maintain the connectivity of the whole network.In theory,the algorithm has certain practical application value.
