EFFICIENT DYNAMIC CHANNEL ALLOCATION TECHNIQUES WITH HANDOVER QUEUINGFOR MOBILE SATELLITE NETWORKS

Efficient dynamic channel allocation techniques with handover queuing suitable for applications in mobile satellite cellular networks, are d iscussed, The channel assignment on demand is performed on the basis o f the evaluation of a suitable cost function. Geostationary and low ea rth orbit (LEG) satellites have been considered, In order to highlight the better performance of the dynamic techniques proposed, a performa nce comparison with a classical fixed channel allocation (FCA) has bee n carried out, as regards the probability that a newly arriving call i s not completely served, It has also been shown that a higher traffic density, with respect to GEO systems, is manageable by means of LEO sa tellites.
