【摘要】：无线传感器网络(Wireless sensor network,WSN)覆盖控制通常采用基于二元感知模型的几何计算方法休眠冗余节点,其算法在实际应用中受到局限,不够精确.针对此问题,本文采用概率感知模型,提出新的覆盖控制算法,将提高能量利用效率作为重要指标,采用节点轮换周期工作机制,每个周期逐个唤醒部分节点,组成满足网络覆盖要求的覆盖集,实现降低能耗、均衡节点能量的目的.概率感知模型描述网络的覆盖能力更精确,算法不受感知模型的限制,原理简单,易实现,仿真结果验证了本算法的有效性.
[Abstract]:Wireless sensor Network (WSNs) coverage control in wireless sensor networks usually uses geometric computation method based on binary sensing model to sleep redundant nodes. In order to solve this problem, a new coverage control algorithm based on probabilistic perception model is proposed to improve the efficiency of energy use. The node rotation cycle working mechanism is used to wake up part of the nodes one by one in each cycle to form a coverage set to meet the requirements of network coverage to reduce energy consumption. The objective of equalizing node energy. The probabilistic perceptual model is more accurate in describing the coverage of the network, and the algorithm is not limited by the perceptual model. The principle is simple and easy to implement. The simulation results verify the effectiveness of the proposed algorithm.
