Capacity Allocation Techniques in a Multi-User Satellite System.

Abstract

The multiple accessing of satellite by a large number of independent users is considered. The messages are generated randomly, and they are of fixed length. Depending on the accessing protocol, such a system may exhibit congestion instabilities, long message delays, or low throughput. Several important protocols (that are applicable to such a system and which fall into the categories of direct access, reservation access, and polling access) are presented and evaluated. The E (delay) vs E (throughput) performances of the various protocols are obtained and compared. Its is shown (for a specific example) that demand assignment access with a TREE reservation protocol is best for throughput up to about 70%, whereas polling access is best in heavier message traffic.
