Energy-Efficient Joint Pushing and Caching Based on Markov Decision Process

Content caching provides a rare trade-off opportunity between low-cost memory and energy consumption, yet finding the optimal causal policy with low computational complexity remains a challenge. In this paper, we formulate the problem of joint pushing and caching at end users in a Markov decision process (MDP) framework with the aim of minimizing energy cost under causal knowledge of the user request delay information and strict delay...
