摘要

为了实现含有移动节点的混合无线传感器网络中的网络覆盖优化,提出了一种点对点的基于模糊逻辑控制器的移动节点导航算法.该算法通过移动节点选择、移动节点向盲区填补坐标径直移动、避让固定节点、避让其他移动节点四个主要步骤,实现移动节点对覆盖盲区的弥补.该算法可以优化网络覆盖,延长网络生命周期,并且在导航过程中兼顾节能与网络负载平衡,综合性地提升网络性能.通过仿真结果与相关算法的分析对比,验证了该算法的有效性和在缩短移动节点导航时间方面的优势.%To optimize the network coverage of wireless sensor networks with mobile nodes, the authors of the paper presents a point-to-point algorithm for guiding mobile nodes to fill coverage holes based on a fuzzy logic controller. For filling the coverage holes by mobile nodes, the algorithm takes the following four main steps: selecting mobile nodes, moving mobile nodes straight to coverage holes, and evading static nodes, evading other mobile nodes. This algorithm optimizes the network coverage, prolongs the life cycle of the networks, takes into account the balance of energy saving and network load and enhances the network performance comprehensively. Compared with other related algorithms, the simulation results verify the validity of the algorithm and its advantage of saving guiding time.
