摘要 降低覆盖冗余度是提高无线传感器网络覆盖度的一种措施.在DCAC(Dynamicadaptive coverageadjustingscheduling)的算法的基础上,给出了边缘节点和局部全约束状态的定义,并且提出了边缘节点的自适应半径调整的算法.与DCAC算法进行比较其仿真结果表明,无线传感器网络的覆盖冗余度相对降低,提高了网络的覆盖度,并且活跃节点的个数相对减少. The lower coverage redundancy is a kind of measures to improve the wireless sensor network coverage. In this paper, the edge nodes and local full constraint condition are defined. At the same time, this paper put forward the edge nodes adaptive radius adjustment algorithm based on the algorithm of DACA（Dynamie adaptive coverage adjusting scheduling）. Finally, the algorithm of DACA joins in the algorithm of this paper and then eompared with the DACA algorithm. The simulation results show that coverage redundancy of the wireless sensor network rela- tively lower, the network coverage improved and the number of active nodes relatively less.
