摘要: 针对无线传感器网络节点能量有限、最小覆盖方法能耗不均衡的问题，该文提出了一种能耗平衡的连通覆盖模型，并对模型进行了分析与仿真。模型利用Voronoi划分和Delaunay三角剖分对传感器网络进行分割，判别重复覆盖目标区域的冗余传感器节点，采用节点到sink点的跳数对节点分层，进而提出选择休眠节点的方法。仿真结果表明，由模型建立的非最小连通覆盖集所导出的无线传感器网络，能够平衡节点能耗、使用优化路由、减弱路由关键点的影响。Abstract: An energy-balanced connected coverage model is proposed for solve the problems that limited energy of sensor nodes and imbalanced energy consumption of minimal connected cover methods make against the lifespan of wireless sensor networks. The model uses Voronoi diagram and Delaunay tessellation to partition wireless sensor network and to distinguish the redundancy nodes overlapping target region, uses hop to sink node to stratify nodes. And then, a method to choose closeable nodes is introduced. The simulation results indicate that the network educed by the non-minimal connected cover set constructed by the model can balance the node energy consumption, use optimized route and weaken the influence of the key points on route.
