Abstract	Edge computing can provide quality assurance for multimedia services. In order to protect the environment, many communities have begun to use green energy, so we add this status to the formulation of the computation offloading mechanism. In this paper, we investigate the computation offloading mechanism for multimedia services in green smart community. First, we introduce a dynamic adjustment mechanism for unit cost of local energy consumption, which makes our algorithm more flexible. Then, we propose a computation offloading mechanism, which aims to decouple the optimization problem and minimize the system cost. We model the computational task offloading decision problem as a distributed potential game, and solve the resource allocation problem using mathematical methods and theories such as Lagrange multiplier method, KKT condition, gradient descent, bisection method, and we also design a CBPA (Computation resource and bandwidth and transmission power allocation) algorithm to optimize edge computing. Finally, simulation results show that the computation offloading mechanism proposed in this paper is effective. © 2020 IEEE.
