摘要: 将纳什交易问题解决方案(NBS)应用到无线网络的资源分配,提出了基于效用的公平分配方案,并通过示例说明了此方案优于原来采用相等效用值的公平方案。本文还提出了上述方案的分布式模型,通过适当的计费机制使所有用户独立地寻求自身净效用最大化,而最终导致网络总效用的最大化。

Abstract: Nash bargaining solution (NBS) is applied to the resource allocation in wireless networks so that a fair allocation scheme, based on utility, was proposed. Through a case study, the new scheme was proved to be superior to the existing scheme of equal utility value. A distributed model of the scheme was also introduced. The users could maximize independently their own net utility with the model in a proper pricing policy. As a result, the network achieves an optimized total utility.

Key words: resource adaptation, utility, fairness, Nash bargaining solution
