摘　　要：为了提升海上异构无线网络中移动节点业务完成率和网络资源配置效率,针对现有网络选择算法与业务需求匹配性较差、动态环境下业务完成率不高的问题,该文提出一种基于Hilbert空间向量赋权的网络接入选择算法。该算法采用基于Hilbert空间的网络-业务匹配模型,将网络特征与业务需求映射至同一空间,在同一坐标系内衡量网络是否满足业务需求;同时,采用基于优劣解距离法的预切换网络选择算法,引入网络-业务匹配权重对优劣解距离法标准化矩阵进行修正,确保所选网络与业务需求相匹配,克服传统网络选择中业务需求考虑较少、网络特征与业务需求难以进行统一衡量的问题。此外,采用基于空间距离的网络切换控制算法,将匹配权重、空间距离引入网络切换控制,保证业务传输连续性,提高动态环境下的业务完成率。仿真结果表明,相较于对比算法,该算法的业务平均完成率提高6.81%以上,有效提升了网络的业务传输能力和通畅度,间接实现了网络资源的有效配置。In order to improve the service completion rate of mobile nodes and the efficiency of network resource allocation in maritime heterogeneous wireless network,a network access selection algorithm based on Hilbert space vector assignment is proposed to address the problems of poor matching between existing network selection algorithms and service demands,and low service completion rate in dynamic environment.The algorithm adopts the network-service matching model based on Hilbert space,maps the network characteristics and service requirements to the same space,and measures whether the network meets the service requirements in the same coordinate system;at the same time,it adopts the pre-switching network selection algorithm based on the Technique for Order Preference by Similarity to Ideal Solution(TOPSIS)method,and introduces the network-service matching weights to correct the normalization matrix of the distance-to-preferred-solution method,so as to ensure that the selected network matches the service requirements,and to ensure that the network matches the service requirements.This ensures that the selected network matches the service requirements and overcomes the problems of traditional network selection where the service requirements are less considered and the network characteristics and service requirements are difficult to be measured uniformly.In addition,the network switching control algorithm based on spatial distance is adopted,and matching weight and spatial distance are introduced into the network switching control to ensure the continuity of service transmission and improve the service completion rate in the dynamic environment.Simulation results show that compared with the comparison algorithm,the service completion rate of this algorithm is improved by at least 6.81%,which effectively improves the service transmission capacity and smoothness of the network,and indirectly realizes the effective allocation of network resources.
