针对如何根据用户的需求在无线网络中选择接入网络的问题,依据不同接入网络之间的非合作关系以及接入网络与用户之间的非合作关系,建立了非合作博弈下的基于支付函数的模型.该模型根据多属性决策理论,运用灰色关联分析法对不同网络的性能参数进行归一化处理,将得到的灰色关联等级作为支付函数进行比较,选出较优秀的网络.通过求解用户与较优秀网络间的纳什均衡,得到用户的接入网络选择.实验结果表明,该方法能够根据用户的需求有效地选择合适的接入网络.
Aiming at the problem of how to select the access network in the wireless network according to the user’s needs, based on the non-cooperation relationship between different access networks and the non-cooperation relationship between the access network and the users, a non-cooperative game based payment Function model based on multi-attribute decision-making theory, the gray relational analysis method is used to normalize the performance parameters of different networks, and the gray relational levels obtained are compared as a payment function to select a better network. User’s Nash equilibrium with the best network, and get the user’s access network selection.The experimental results show that this method can effectively select the appropriate access network according to the needs of users.
