Handover Requests Queuing in Low Earth Orbit Mobile Satellite Systems
This paper deals with a study on resource management strategies in Low Earth Orbit Mobile Satellite Systems (LEO-MSSs). A suitable mobility model has been proposed. Fixed Channel Allocation (FCA) and Dynamic Channel Allocation (DCA) have been considered. Moreover, we have foreseen that inter-beam handover requests, which do not immediately find service, can be queued in order to reduce the handover failure rate. Two different queuing disciplines have been assumed. An analytical approach has been developed to compare these queuing strategies and its results have been validated through simulations.
