摘要：
In this paper, we consider wireless caching in device-to-device (D2D) cooperative networks and propose a new definition, energy-consumption-ratio (ECR), to measure the energy efficiency that caching schemes can achieve. Based on this definition, we formulate an optimal energy-efficient caching problem and develop a caching scheme, named SBRC-2S. Simulation results show that the proposed scheme outperforms the existing ones and approaches the optimal performance bounds in terms of energy efficiency.
