基于效用理论的异构无线网络选择
Access Selection Algorithm Based on Utility Theory in Heterogeneous Wireless Network Environment
摘要
Abstract
In future heterogeneous wireless network environment,mobile users always want to be able to access the most appropriate network to satisfy the demand of data service.To work out the problem that exists when normalized index value serves as decision value, the utility theory is applied to multi⁃attribute algorithm,and the utility function of index under different services,terminal states and user types is given,and the normalized index value is replaced by utility value to calculate total utility of alternative network, finally the optimal network is selected by the comparison of total utility value. Simulation shows that this algorithm can better reflect the needs of users,and help choose network suitable for the user.关键词
