Abstract
In this paper, the capability is investigated of a reservation TDMA-based
protocol to support constant bit rate and best-effort traffics in
Low Earth Orbit (LEO) satellite communication systems under typical
propagation conditions. Differently from several previous papers
on the same subject, we focus here on a communication channel affected
by multipath fading and characterized by a high round trip delay.
In our protocol, a higher priority is given to constant bit rate
terminals with respect to best-effort data terminals. The performance
for constant bit rate and best-effort terminals was derived by means
of a suitable analytical approach and computer simulations. The results
shown herein permits to evaluate the influence of the channel propagation
conditions on the system performance. Moreover, they highlight that
the reservation TDMA protocol exhibits a good behaviour for the communication
channel under consideration and in comparison with a recent protocol
based on the classical PRMA scheme.
