摘要
为了减小山地森林环境对无线传感器网络节点选址的影响,提出集成三维GIS的节点优化选址层次分析模型。从监测位置、地形遮挡、有效覆盖、光照辐射、可视域范围五个评价因子建立节点优化选址递阶层次结构;通过三维GIS空间分析得到各候选节点评价参数,运用层次分析法(AHP)确定各评价因子权重,建立节点优化选址评价模型;解算评价矩阵实现节点优化选址。工程实例表明,该模型能够简化选址流程,对山地森林环境下的节点选址有较高的精准性。
In order to reduce the impact of mountain forest environment on the location of wireless sensor network nodes, an analytic hierarchy model of nodes optimal location integrated with 3 D GIS is proposed. A hierarchical structure of the nodes optimal location was built from five aspects: monitoring location, terrain occlusion, effective coverage, light radiation and view range. The evaluation parameters of each candidate node were obtained using spatial analysis functions of three-dimensional GIS, and the weights of each evaluation factor were determined by using the analytic hierarchy process(AHP), and an evaluation model of node optimal location was established. The optimal location of nodes was obtained by calculating the evaluation matrix. The examples of engineering have shown that this model can simplify the process of node location, and has high accuracy in mountain forest environment.
