异构网络无线资源管理中的非合作博弈

Noncooperative Game for Radio Resource Management in Heterogeneous Wireless Networks

蜂窝网与无线局域的网融合网络可以为移动用户提供宽带连接以及可靠的服务质量保证.本文在这样的无线融合网络中提出非合作的博弈模型,用于网络的无线资源管理.首先,一个长期的博弈被提出用于指导两种网络对各类业务的带宽分配.然后,在此带宽分配的基础上,一个短期的博弈又被提出用于指导两种网络的呼叫接纳控制策略.通过求取这两个博弈的纳什均衡,可以使两种网络所获得的总效用都达到最大.

The integrated WLAN and cellular networks will provide high-bandwidth connectivity with quality-of-servtce （QoS） support to mobile users in a seamless manner. We present a noncooperative game for radio resource management （i. e. , bandwidth allocation and admission control） in such a heterogeneous wireless access environment. First, a long-term noncooperative game is used to obtain the bandwidth allocations to various traffics from the different access networks. Second, based on the obtained bandwidth allocation, another short-term noncooperative game is formulated to obtain the admission control. The Nash equilibriums for both games give the optimal radio resource management which maximizes the total utilities of each network.
