Before revision:  In this paper, we consider the energy consumption tradeoff among communication, computation, and caching (C3) for data analytics under a Quality of Information (QoI) guarantee in a geo-distributed system. To attain this goal , we formulate an optimization problem to capture the C3 costs, which turns out to be a non-convex Mixed Integer Non-Linear Programming }  (MINLP) Problem.
