Some general approaches for performance analysis of the ALOHA-based satellite channel

A satellite link has been employing as the minor part of a data network for many years, but it is a hard task for engineers to initially design and evaluate a network employing both terrestrial and satellite links, since the satellite scheme from each vendor has different aspects and conditions, though their basic structures are similar. This paper presents a general model of satellite channel with multiple access scheme. It employs a simple flow basis of the number of blocked stations to represent system behavior at equilibrium point. The model has a general and plain structure and, thus, has the benefit of: 1) easy conformation to different types of satellite channel where rudimentary structure is random access method, especially slotted ALOHA, for inroute channel; 2) results are expressed in terms of general performance measures which could be painlessly interfaced to a terrestrial network. Finally, results obtained from simulation and numerical computation are presented and compared
