Energy efficiency in future green cellular wireless networks poses a challenge to operators and researchers. An effective method of providing energy savings (ES) in base stations (BSs) is to switch off idle BSs or put them into sleep mode and subsequently migrate the traffic loads to active BSs in their neighborhood. The intrinsic issue related to such methods applied to heterogeneous networks (HetNets)...
Aiming to resolve insufficiency of existing Energy-Saving (ES) methods in heterogeneous network, a novel self-organizing ES mechanism to improve energy efficiency suitable for heterogeneous networks is proposed. In the mechanism, we come up with the self-organizing procedures, the traffic model, and an optimizing objective model. The mechanism is then simulated under an urban LTE scenario with 7 macro...
