基于时隙阿罗哈的无线接入与自私的用户可能会导致系统资源的使用效率非常低。为了在此类系统中实现合作和公平，我们提出了一种最优定价策略，服务提供商可以根据该策略调节整体网络行为。由于用户的效用包含了使用频谱所支付的价格，因此通过努力提高自己的性能，用户会采取行动来优化整体网络性能。我们的分析基于博弈论框架，我们考虑数据包接收的简单碰撞模型以及物理层的多数据包接收功能。所提出的定价策略在平等访问概率的约束下强制执行公平性。
Wireless access based on slotted Aloha with selfish users may result in very inefficient use of the system resources. To impose cooperation and fairness in such systems, we propose an optimal pricing strategy, based on which the service provider can regulate the overall network behavior. As the users’ utility incorporates the price paid for using the spectrum, by striving to improve their own performance, the users act to optimize the overall network performance. Our analysis is based on a game theoretic framework, and we consider both the simple collision model for packet reception, as well as multipacket reception capabilities for the physical layer. The proposed pricing strategy enforces fairness under the constraint of an equal access probability.
