Summary:Wireless caching has been used to improve network performance and reduce bandwidth and energy consumption. In this paper, we study the issue of joint admission control and content caching for wireless access points with energy harvesting capability. Given limited energy supply, the access points, in a competitive environment, aim to maximize their payoff defined in terms of revenue by optimizing their admission control and content caching policy. Moreover, the throughput of the content transmission by the access point has to be maintained above a certain threshold. Thus, we propose a constrained stochastic game to model this competitive caching scenario. The equilibrium policy, which is a mapping from the energy, cache, and demand states to the action, is obtained from the model. From the performance evaluation, the joint admission control and content caching policy can achieve significantly better performance than that of the baseline schemes, especially when the energy harvesting rate becomes constricted.
