摘要:

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.

Abstract:

The coexistence of various wireless access networks has been widely recognized in the next generation network. As a different network access form, how the clients at the instance of their needs will select the access network has become a widespread concern. For this problem, according to the noncooperation between different access networks and the noncooperation relationship between the access network and the clients, a non-cooperative game model based on the payoff function is established. On the basis of the multi-attribute decision theory, the model uses the gray correlation analysis method to normalize the performance parameters of the network, chooses the grey relation grade as the payoff function, compares and selects excellent networks which the clients can access. By solving the Nash equilibrium between the clients and excellent networks, the clients can access the appropriate network. Experimental results demonstrate that the method can effectively select the appropriate network according to the needs of the clients.
