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)...
Reducing the energy consumption (EC) of base station (BS) is one of the major concerns in wireless cellular networks. Additionally, turning off some underutilized BSs during off-peak period and performing effective compensation without delay are the most efficient way to save energy. However, large-scale energy conservation yet remains to be investigated at macro level. In this paper, to solve the...
Green communication has been a hot issue with the energy consumption of ICT industry continuously growing. To achieve the goal of energy saving, base station sleep schemes are extensively investigated; however, they are hard to implement in actual commercial network for the risk of losing of users. So in this paper, we try another way to improve the energy efficiency of LTE network by interworking...
Energy issue of cellular access network has drawn much attention in the recent years. In this paper, we propose a Novel Energy-Saving Cell Selection Mechanism (ESCSM) including the energy-saving triggering conditions determination and a regional cell selection algorithm based on traffic. ESCSM selects the BSes which can be switched off without any negative effects to the radio coverage and service...
