C-PRMA: a centralized packet reservation multiple access for local wireless communications

Abstract
Packet switched technology has been demonstrated effectivein cellular radio systems with short propagation delay, not onlyfor data but also for voice transmission. In fact, packet voicecan efficiently exploit speech on-off activity to improve bandwidthutilization over TDMA. Such an approach has been firstsuggested in the Packet Reservation Multiple Access (PRMA)technique, an adaptation of the Reservation ALOHA protocolto the cellular environment. However, being PRMA based ona fixed...
