Smart switch: Optimize for green cellular networks

Energy efficient in cellular networks is an increasingly important issue. Base Station(BS) subsystem consumes the major chunk of infrastructure energy, however, it is not energy proportional relative to its carried traffic load. This paper formulates the energy optimization problem to balance the two conflicting objectives: maximizing BS energy reduction and minimizing switch operations. We propose a heuristic offline approach, dubbed Smart Switch, which saves energy significantly while maintaining infrequent BSes switch operations.
