Joint Radio Resource Allocation and Base Station Location Selection in OFDMA Based Private Wireless Access Networks for Smart Grid

Abstract EN

This paper studies the base stations deployment problem in orthogonal frequency-division multiple access (OFDMA) based private wireless access networks for smart grid (SG).

Firstly, we analyze the differences between private wireless access networks for SG and public cellular access networks.

Then, we propose scheduling and power control based algorithms for the radio resource allocation subproblem and K-means, simulated annealing (SA), and particle swarm optimization (PSO) based algorithms for the base station (BS) location selection subproblem and iterate over these two sets of algorithms to solve the target problem.

Simulation results show that the proposed method can effectively solve the target problem.

Specifically, the combination of power control based resource allocation algorithm and PSO based location selection algorithm is recommended.
