Optimizing base stations deployment in wireless access networks for smart grids

This paper studies the base stations deployment problem in long-term evolution (LTE) based private wireless access networks for smart grid (SG). First we analyze the differences between private wireless access networks for SG and public cellular access networks. Then we propose an algorithm including device grouping, power control, and priority procedure for the channel allocation sub-problem and an algorithm based on particle swarm optimization (PSO) for the site selection sub-problem. Finally we propose an overall approach to iterate over these two algorithms to solve the target problem. Simulation results show the proposed approach can effectively solve the target problem.
