TÓM TẮT
Installation of backup power supply plays an important role in maintaining communication services which helps saving billions of dollars as well as human lives during natural disasters. However, being costlier than public power, it increases the capital expense of the base stations. While downsizing the backup power source, it can significantly downgrade the quality of services due to insufficient power supplies. In case of co-location of multiple mobile network operators at a single base station, sharing backup power sources among the operators is a possible economical solution to reduce the delay of traffic flows and enhance power usage. In this paper, we have used Nash Bargaining solution and decentralized convex optimization over operators to determine the optimal user association distribution so that we can get maximum improvement in the delay performance of each operator while fairly sharing the backup power.
