A single host network selection algorithm for heterogeneous wireless networks

异构无线网络的资源管理是异构无线网络的关键技术之一.针对异构无线网络环境下的单宿主用户,提出了一种单宿主的网络选择算法.该算法在用户端利用层次分析法(AHP)确定网络属性的权重,然后利用逼近理想解法(TOPSIS)选择最优网络.仿真结果表明,该算法可有效降低系统阻塞率.同时能够更好保证高优先级用户的接入质量.

Resource management in heterogeneous wireless networks is one of the key technologies in heterogeneous wireless networks. According to the single host user in heterogeneous wireless network environment, a network selection algorithm based on single host is proposed. Algorithm uses the analytic hierarchy process （AHP） to determine the weights of the network attributes, and then select the optimal network by approximating the ideal solution （TOPSIS）. Simulation results show that the algorithm can effectively reduce the blocking rate of the system. At the same time, it can better ensure the quality of access to high priority users.
