摘　　要：为了更好地满足覆盖要求,提出了一种基于节点序列动态均衡策略算法;该算法通过节点与目标的几何映射关系,利用移动节点对覆盖区域局部模型进行有效覆盖,其覆盖过程是通过节点移动策略加以判断网络覆盖情况,减少了不必要的覆盖过程,增强对所关注目标节点的覆盖,从而达到了多重有效覆盖与连通的目的;实验结果表明,在不同的覆盖区域和有无边界情况下,该算法不仅可以使用最少节点完成对覆盖区域的局部有效覆盖,而且通过节点的移动和调度策略平衡了所有节点的能量消耗,完成了有无边界影响下的覆盖与连通,进而延长了网络生存周期。In order to better meet the coverage requirements, proposes dynamic equilibrium strategy algorithm based on node sequence in WSN, geometry mapping between the algorithm by node and the target, effectively covering on the partial coverage model region using the mobile node, the covering process is through the node energy consumption size to node mobility strategies to determine the network coverage, thus eliminating the the process of covering loopholes and is not fully covered, so as to achieve the multiple covers. The experimental results show that, the algorithm can not only use the minimum node to complete the local effective coverage area, and through the mobile strategy and scheduling node balance the energy consumption of all nodes, and prolong the network life cycle.
