中文摘要：

提出了一种节点位置无关的连通性覆盖协议.协议首先利用了随机部署网络在已知监测区域大小和节点感知范围情况下,应用期望的覆盖质量与所需的工作节点数量之间的数学关系,随机选取工作节点满足应用需求;然后根据每个节点距基站最小跳数,执行Add-On规则,增加额外节点保证网络连通.实验结果表明,EECPC协议能够在较长时间内能量有效地提供满足应用要求的覆盖率,而且保证网络连通.

英文摘要：

A location-unaware connected partial coverage protocol is proposed, which utilizes an integrated method that provides statistical sensing coverage and guaranteed network connectivity. First, a mathematical method for coverage analysis is presented. Using the method, given the ratio of the sensing range of a sensor node to the range of the entire deployment area, the number of the working nodes needed to reach the expected sensing coverage can be derived. Second, based on its minimum hop to sink node, the proposed Add-On rule can turn on some extra sensor nodes, with which the network connectivity is guaranteed. Simulation results demonstrate the LUCPC can achieve user-specified coverage quality with guaranteed network connectivity.
