Abstract
Recently the Packet Reservation Multiple Access protocol PRMA++ was proposed as a MAC protocol for future mobile communication systems. As the reservation mechanism of this protocol is based on slotted ALOHA, instabilities in the random access phase can induce it to work inefficiently. This paper studies the contention mechanism of PRMA++. By analysing its dynamic behaviour we identify efficient and inefficient operation points of PRMA++ and point out a numerical method to adjust the retry probability of collided request packets so that PRMA++ operates efficiently. The proposed analysis method drastically reduces computation complexity and hence enables the investigation of systems with a high number of active mobile stations.
