摘　　要：针对目前无线传感器网络中缺乏合理的共享节点转化算法的问题,提出一种改进的锚节点转化算法。该算法以距离最远原则选择个别共享节点转化为锚节点来实现更多的节点定位,以达到能量消耗最小、最大延长传感器网络寿命的目标。算法简单、通信计算量及复杂度明显降低,且保持了较高的定位精度与覆盖率。结合煤矿环境中锚节点布设受限的实际情况,对高能效的算法进行了验证。In view of lackness of schared nodes transformation algorithm in current WSN network, an algorithm for transformation of the anchor nodes was improved. It＇s principle of selection individual node is farthest away from anchor nodes, to achieve more nodes positioned, with the minimum energy consumption and largest extending sensor network lifetime targets. Algorithm is simple itself, and communication computing complexity is significantly reduced, maintaining high positioning accuracy and coverage. Its energy-efficiency has been verified, according to anchor nodes limited in coal mine.
