Green resource allocation for user access in cloud-based networks

Abstract

In this paper, we investigate green power control for user access in cloud-based cellular networks. The optimization problem is formulated as a non-convex and a non-linear mixed-integer fractional form considering the circuit power consumption. In order to solve the considered problem, we transform the considered optimization problem into a tractable subtractive form problem, where the solution can be obtained through three-stage optimization. The outer layer only refers one-dimension search for a parameter which can be obtained through bisection search. In the second stage, a non-fractional power control problem remains to solve, and we exploit a power update function to update the transmit power. The third stage performs user access. Simulation results indicate that our proposed algorithm archives better performance than the traditional algorithm.
