摘　　要：针对海上异构无线网络中现有的节点选择算法存在的实时有效性和与移动节点匹配性较差的问题,提出了一种基于动态层次分析(dynamic analytic hierarchy process,DAHP)法和协同学原理的网络接入选择算法。该算法在满足多因素判决和静态节点网络选择的基础上,采用DAHP法确定接入判决指标的主观权重,运用协同学相关原理确定客观权重,利用接收功率确定移动节点的位置权重,并通过对主、客观和位置权重进行再分配,实现了对移动节点周围的实时网络状态与任务通信需求的兼顾,提高了算法实时性和与移动节点的匹配性。仿真结果表明,该算法相对于基于传统AHP和协同学原理的网络选择算法、基于距离的移动节点算法,能够在降低节点业务阻塞率的同时提高通信通畅度与实时性。In order to solve the problem that the node selection algorithm in marine heterogeneous wireless network is not effective in real time and does not match well with mobile nodes,a network access selection algorithm based on dynamic analytic hierarchy process(DAHP)and synergetic principle is proposed.On the basis of satisfying multi factor decision and static node network selection,this algorithm uses the DAHP method to determine the subjective weight of the access decision index,uses the synergetic correlation principle to determine the objective weight,and uses received power to determine the location weight of mobile nodes.By redistributing the subjective,objective,and location weights,it takes into account the real-time network state and task communication needs around mobile nodes.The algorithm improves the real-time performance and the matching with mobile nodes.The simulation results show that compared with the traditional network selection algorithm based on AHP and the synergetics principle and the mobile node algorithm based on distance,this algorithm reduces the traffic blocking rate of nodes and improves the communication smoothness and real-time performance.
