A novel multiobjective cell switch-off framework for cellular networks

Cell switch-off (CSO) is recognized as a promising approach to reduce the energy consumption in the next-generation cellular networks. However, CSO poses serious challenges not only from the resource allocation perspective but also from the implementation point of view. Indeed, CSO represents a diff...
