چکیده
The Universal Mobile Telecommunications System (UMTS) will provide multimedia services to users in whatever environment via uniform service access procedures. Efficient Medium Access Control (MAC) protocols are needed to guarantee high capacity. This paper deals with Packet Reservation Multiple Access (PRMA), an efficient MAC protocol that has been widely studied in terrestrial microcellular systems. We investigate the suitability of PRMA for supporting voice and data transmissions in a UMTS based on Low Earth Orbit Mobile Satellite Systems (LEO-MSSs). It is shown here that, through a suitable choice of the system parameter values, the PRMA protocol may achieve a good quality of service also in LEO-MSSs.

Performance analysis of a PRMA protocol suitable for voice and data transmissions in low Earth orbit mobile satellite systems
Mobile satellite systems (MSSs) are expected to play a significant role in providing users with communication services worldwide. In such context, low earth orbit (LEO) satellite constellations seem to be a good solution to attain a global coverage and to allow the use of low-power lightweight mobile terminals. This paper analyzes the performance of a novel medium access control (MAC) scheme su...
متن کاملC-PRMA: a Centralized Packet Reservation Multiple Access for Local Wireless Communications
Packet switched technology has been demonstrated effective in cellular radio systems with short propagation delay, not only for data but also for voice transmission. In fact, packet voice can efficiently exploit speech on-off activity to improve bandwidth utilization over TDMA. Such an approach has been first suggested in the Packet Reservation Multiple Access (PRMA) technique, an adaptation of...
متن کاملPRMA Performance Evaluation Based on Queueing Theory
The Packet Reservation Multiple Access (PRMA) protocol has been proposed as a candidate for the third generation of mobile radio systems to obtain a statistical multiplexing gain from the bursty character of speech, probably the main service to be provided by a mobile network. The PRMA is derived from the slotted Aloha protocol, and being a reservation protocol makes it suitable to cope with th...
