摘　　要：为了提高大型WSNs的网络资源配置效率,提出一种分布式离散化的最优Sink移动路径求取方法,在博物馆环境监测中引入基于移动Sink的无线传感器网络。首先,各节点无需全局采集路由信息,通过综合考虑邻居数、与Sink之间的距离等因素分布式采集数据;其次,构造全新的转换矩阵,将移动距离约束下最长停留时间问题转化为约束条件下最短路径的求解问题;最后,将标准Leach和移动节点两种算法运用在博物馆展览馆实际场景中,对两种算法的执行时间和网络生存时间进行了比较。结果表明,移动节点方式提高了网络的网络生成时间,节约了各节点的能量损耗,消除了无线传感器网络的"能量空洞"问题,具有较强的应用和推广价值,能够胜任博物馆场景的应用。A distributed discretization optimal Sink mobile path finding method is proposed to improve the efficiency of network resource allocation for large⁃scale WSNs.A wireless sensor networks(WSNs)based on mobile Sink is introduced into the museum environmental monitoring.Each node does not need to collect routing information globally,and can collect data with distributed by overall consideration the quantity of neighbors,the distance from Sink and other factors.A new transformation matrix is constructed to transform the longest residence time problem under moving distance constraint into the shortest path problem under constraints.The standard Leach algorithm and mobile node algorithm are applied into the exhibition actual scene of the museum,and the execution time and the creation time of networks of the standard Leach algorithm and mobile node algorithm are compared.The results show that the mobile node algorithm can increase the creation time of networks,save the energy loss of each node,and remove the“energy hole”of the WSNs.It has strong application and promotion value,and is competent for the application of the museum scene.
