چکیده

Efficient satellite resource management and allocation techniques aim at providing reliable real-time service, taking into consideration the scarcity of resources and the large number of handovers. This paper presents algorithms and modules for accurate satellite and beam handover prediction at the SBS. The call is assigned to that path which provides the highest preference factor. Several alternative solutions for path selection are proposed and evaluated in terms of time consumption and computational intensity. Keywords— Mobile satellite systems, handover, resource allocation, path selection

Supporting QoS over Handovers in LEO Satellite Systems

Low Earth Orbit (LEO) satellite networks are characterized by topology variations. Although space segment topology varies periodically, connections of mobile stations (MS’s) to the satellite network alter stochastically. As a result the quality of service delivered to users may degrade. Different procedures have been proposed either as part of a resource allocation mechanism or as part of an en...

A New Connection Admission Control for Spotbeam Handover in LEO Satellite Networks

Frequent spotbeam handovers in low earth orbit (LEO) satellite networks require a technique to decrease the handover blocking probabilities. A large variety of schemes have been proposed to achieve this goal in terrestrial mobile cellular networks. Most of them focus on the notion of prioritized channel allocation algorithms. However, these schemes cannot provide the connection-level quality of...
