| 摘 要： | 将异构网络中的网络选择转化为典型的动态多指标决策问题,提出了一种基于动态多指标决策理论和灰色关联理论的网络选择策略。在考虑用户偏好、业务应用和网络参数当前好坏程度的基础上,进一步考虑了网络参数的动态变化趋势,从而为用户提供全面的QoS保证。仿真结果表明,这种策略能为用户提供合理的接入选择。

| Abstract: | The network selection problem in heterogeneous networks is transformed into typical dynamic multi-attribute decision making （DMADM） problem. A network selection strategy is proposed based on dynamic multi-attribute decision making theory and gray relation analysis （GRA） theory. The dynamic change trend of network parameters is taken into account besides user preference, service application and the current level of network parameters to provide users with comprehensive QoS guarantee. The simulation results show that this strategy could provide mobile users with reasonable access selection. |
