Dynamic reorganization of cell structures in wireless networks. The present invention relates to wireless communications and, more particularly, to energy usage of wireless equipments in wireless communications. Currently there are mechanisms in use that can selectively turn of carriers in a BTS depending on the traffic load. But due to the fixed costs of operating the base station even when there are no active users, turning off entire BTS will give more energy savings than simply reducing capacity by turning off carriers at low load. Embodiments herein detect a change in demand on the network and re-organize the cellular network by selectively turning off BTSs and appropriately increasing the coverage area of other BTSs, and arrive at a configuration that optimizes the energy consumption of the cellular network as a whole.
