首发时间:2013-05-13
摘要:针对面向数据采集的无线传感器网络中的覆盖面与能耗问题,提出一种基于覆盖概率模型的无线传感器网络覆盖算法,该算法根据节点间的欧氏距离计算节点的有效覆盖率,进而根据网络的覆盖质量要求选择覆盖监控区域的工作节点。仿真实验表明,该算法能够使用较少的工作节点满足网络的覆盖要求,在减少盲区的同时,可以有效地降低整体网络的能耗,延长网络的生存期。

Coverage algorithm based on coverage probability model for wireless sensor network
Abstract:Due to the problem of energy consumption and coverage in wireless sensor network (WSN) for data acquisition, a coverage probability model-based coverage algorithm (CPMCA) is proposed. In the CPMCA, the node’s effective coverage probability is computed based on the Euclidean distance between wireless nodes, and then working nodes of coverage monitoring area are selected based on the requirement of network coverage quality. The simulation results show that the CPMCA can meet the requirement of network coverage quality with less nodes, reduce the area of network blind spots, reduce the energy consumption of network effectively and prolong the network lifetime.
Keywords: wireless sensor network coverage probability model energy consumption lifetime
