Abstract
The throughput performance of multi-access schemes for data traffic through a satellite channel is analyzed in this paper. Three general schemes are described: channel reservation schemes, random access schemes, and padket reservation schemes. This thesis considers only the random access schemes. Analysis and comparison between ALOHA and Slotted ALOHA are made, but the main emphasis is on satellite channel throughput. A continuous transmission protocol for Slotted ALOHA is suggested in which each ground earth station repeats the transmission of each packet in a number of random repetition slots. The channel is idle when no ground station (GS) is transmitting on it. With the continuous scheme idle periods can be reduced, and channel throughput can be increased. In order to have the maximum throughput with continuous transmission, an optimum number of copy packets with no collision can be determined. A study of different numbers of copies, the probability of collision with each, and the probability of idle channel leads to the choice of an optimum number of copies for various traffic loads.
