无线服务提供商的竞争
On Competing Wireless Service Providers
摘要：
我们考虑的情况下，无线服务提供商竞争异构无线用户。用户的付费意愿和个人渠道收益各不相同。在一般渠道模型下，证明了两个服务提供商竞争的纳什均衡的存在唯一性。有趣的是，两个供应商的竞争导致了全球最佳结果。我们将一些结果扩展到两个以上的供应商竞争的情况。最后，我们提供了数值例子来说明各种参数对纳什均衡的影响。
英文摘要：
We consider a situation where wireless service providers compete for heterogenous wireless users. The users differ in their willingness to pay as well as in their individual channel gains. We prove existence and uniqueness of the Nash equilibrium for the competition of two service providers, for a generic channel model. Interestingly, the competition of two providers leads to a globally optimal outcome. We extend some of the results to the case where more than two providers are competing. Finally, we provide numerical examples that illustrate the effects of various parameters on the Nash equilibrium.
