In space information network (SIN), Low Earth Orbit (LEO) satellites or aircrafts need to communicate with Geostationary Orbit (GEO) satellites. However, due to the non-uniform distribution of traffic in SIN, the load of each beam is different, thus the heavier loaded beams may increase the traffic transmission time. In order to reduce the transmission time, a multi-beam load balancing scheme based...
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....
Network designers expect a highly mobile, highly responsive, and quickly deployable network structure to enable communication in emergency situations. For this reason, a major research goal for emerging mobile network (mobile sensor network, mobile ad hoc network, etc.)is to achieve good coverage and robust communication performance by coordinated management of base stations or nodes. In this paper,...
Carrier aggregation (CA) is an effective approach to achieve high transmission rate and wideband communication, which are the significant features of Long Term Evolution-Advanced (LTE-A). Component carrier (CC) selection plays an important role in CA technology. An appropriate CC selection method is necessary to improve the system performance in terms of load balancing and channel quality. A Hierarchy...
