摘要
对移动通信网络节点最优路径进行有效选择,可提升移动通信网络通信质量。进行最优路径选择时,应建立各个节点的数据传输能量消耗模型,给出能量消耗最小的节点集合,在能量消耗最小的前提下进行路径选择,但是传统方法无法精确地计算出各个节点的通信能量损耗,最优路径选择过程需要消耗大量的能量,且节点选择误差较大。提出基于空间自相关的移动通信网络节点最优路径选择方法。组建当各个节点传输能量消耗模型,获取能量消耗最小的节点集合,融合于空间自相关原理定义移动通信网络节点度值,利用上述值度量网络中各个节点的重要性,给出网络中最优节点的评价函数,并完成对移动通信网络节点最优路径选择。仿真结果表明,所提方法降低了节点最优路径选择误差,可以为移动通信网络通信质量的提升奠定有力基础。
In this paper, we proposed an optimal path selection method of node in mobile communication network based on spatial autocorrelation. Firstly, the energy consumption model of each node transmission was built and the node set with minimum energy consumption was obtained. Then the spatial autocorrelation theory was integrated to define the node degree value. The importance of each node in network was measured using the value mentioned above. Finally, we gave out the evaluation function of optimal node in network and completed the optimal path selection of node in mobile communication network. The simulation results show that the method mentioned above reduces the selection error. It can establish the strong basis for the improvement of communication quality of mobile communication network.
