摘　　要：随着智能物联网的快速发展及运用,其对网络的使用寿命、可靠性及覆盖范围提出了新的挑战.目前的无线传感器网络(wireless sensor network,WSN)是由大量部署在监测区域内的自组织型传感器节点组成,其具备低成本、节能、自组织和大规模部署等优势.然而,如何在此基础上进一步延长网络寿命,提高WSN的覆盖可靠性,是当前研究面临的主要挑战.为此,将骨干网络与覆盖模型、传感器节点协同感知和空间相关性结合,提出了一种覆盖可靠性评估模型.在此基础上,提出了一种基于可信信息覆盖的覆盖可靠性优化算法,一方面,利用可信信息覆盖模型保证数据的协同感知,增强网络服务质量,另一方面,采用骨干网络优化路由,节省能量消耗.进一步地,为验证所提算法的优越性,以传感器多状态、覆盖率为评价指标,以RMSE阈值和能耗为性能指标,将所提算法与ACR和CICR算法进行对比.最后,在Matlab仿真软件上搭建了验证模型,仿真结果表明,所提算法能显著提高覆盖可靠性.With the rapid development and application of Artificial Intelligence and the Internet of Things(AIoT),new challenges are posed to the network’s useful life,reliability,and coverage.The current wireless sensor network(WSN)consists of a large number of self-organizing sensor nodes deployed in monitoring areas,exhibiting advantages such as low cost,energy efficiency,self-organization,and large-scale deployment.However,how to further extend the network life and enhance the coverage reliability of wireless sensor networks remains a primary challenge in current research.To address these challenges,a coverage reliability assessment model is proposed by integrating the backbone network with coverage models,collaborative sensing of sensor nodes,and spatial correlation.Subsequently,a coverage reliability optimization algorithm based on the confident information coverage model is proposed.On one hand,the algorithm utilizes the confident information coverage model to ensure collaborative sensing of data,enhancing network service quality.On the other hand,it employs backbone network optimization for routing to conserve energy consumption.Furthermore,to validate the superiority of the proposed algorithm,sensor multi-states,and coverage rate are taken as evaluation metrics,with RMSE threshold and energy consumption as performance indicators.The proposed algorithm is compared with ACR and CICR algorithms.Finally,a verification model is built on Matlab simulation software.Simulation results demonstrate that the proposed algorithm significantly improves coverage reliability.
