The increasing demand for high bandwidth in cellular wireless networks led to a dramatic increase in the number of deployed LTE femtocell base stations (FBS) in recent years. While the energy consumed by a single FBS is relatively negligible, the collective energy footprint of all FBSs deployed by an operator turns out to be huge. Energy-efficient protocols are needed thus to balance the trade-off...
This paper proposed an asymmetric QoS mapping mechanism in the handover between terrestrial and satellite networks which reduces handover blocking probability. This mechanism makes users in the terrestrial network degrade their requirements to access the satellite network with lower QoS class than they have in the terrestrial network when traditional one-one mapping fails. The users can recover their...
