Load balancing (LB) plays a key role in improving the performance of hybrid Geostationary Orbit (GEO)-Low Earth Orbit (LEO) satellite network. Overload is very common in LEO satellite due to the non-uniform distribution load and the periodic satellite motion. A feasible approach to realize load balancing is that the terminals (destination nodes) served by LEO satellite hand over to GEO satellite....
The access point sleeping scheme is an efficiency method for power saving in the cellular networks. This paper proposes a QoS-aware adaptive access point sleeping scheme designed for energy efficiency in the relay cellular networks. To achieve the best tradeoff between QoS guarantee of users and the power saving of the network, the optimization problem of the access point selection for each user is...
Mobility load balancing (MLB) is an effective method employed by 3GPP to transfer traffic from a hot-spot cell to neighbouring cells. This paper designs a cooperative mobility load balancing (CMLB) scheme in relay cellular networks. After partner cell selection, in the traffic shifting stage, the partner cell analyses hot-spot cell's traffic shifting request and the idle spectrum of relay station...
