At present, the energy consumption of wireless communication network accounts for the vast majority of the operator's expenses. A cooperative energy saving mechanism is proposed in the framework of the self-organized network, based on the hybrid energy supplied, aiming at the energy consumption of cellular is too large and the utilization rate of green energy is low. According to the framework, the...
The current power consumption of intelligent terminals are over burden for their battery capacities, which directly restrict the hours used. In order to realize the energy saving of terminals in the LTE-A system, this paper puts forward the concept of virtual cells and a related uplink energy saving mechanism. Virtual Cell's resources and the outage probability of terminals are proposed by this mechanism...
For the sake of the increase of energy consumption, the emission of carbide can't be negligible. In this paper, we propose a mathematical model which adjusts the radius of base station, to figure out the problem of energy saving, while the quality of services such as the traffic volume of each base station and the service area should be satisfied. For the model, we use ant colony algorithm as a practical...
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...
Home NodeB Gateway (HNB-GW) is a mobile operator's equipment through which Home NodeB (HNB) gets access to the core network. Without a Load Balancing (LB) mechanism, HNB-GWs' load distribution is determined by the random access of HNBs. HNB-GWs with too many HNBs may become overloaded easily. Once a HNB-GW is overloaded, other entering HNBs cannot be accepted and serviced due to the one-to-many relationship...
