无线传感器网络中采用二元感知模型方法计算休眠冗余节点具有局限性和不精确性.本文考虑到实际应用环境对节点感知能力的影响以及传输过程中的路径损耗问题,对监测区域采用三维网格建模,并在概率感知模型的基础上提出一种概率感知衰减模型,同时对当前二维覆盖控制算法存在的各种局限性,提出了一种基于概率的分阶段冗余唤醒策略.仿真结果表明,该算法均衡了网络节点能量,实现了网络能耗的有效性,延长了网络的生存期.
Wireless sensor networks using binary sensing model to calculate dormant redundant nodes have limitations and inaccuracies.In this paper, taking into account the practical application of the environment on the node perception and path loss during transmission, the monitoring area using three-dimensional network Based on the probabilistic perception model, a probabilistic perceptive attenuation model is proposed. At the same time, a variety of limitations of the current two-dimensional coverage control algorithm are proposed, and a staged redundant wake-up strategy based on probability is proposed. The result shows that this algorithm balances the energy of network nodes, realizes the efficiency of network energy consumption and prolongs the lifetime of network.
