Abstract :
A reservation multiple-access protocol for mobile communications in a microcellular environment is proposed and investigated under high-load conditions, both analytically and by simulation. The reservation scheme proposed uses a reservation channel of the slotted-ALOHA protocol type and an adaptive retransmission probability for stable operation. The capacity of the reservation channel varies with the load above a certain threshold (reservation capacity threshold); in that respect it is a compromise between the R-ALOHA and ALOHA-reservation protocols, both proposed for satellite communications, and the PRMA, an R-ALOHA-type protocol proposed for short-range mobile communication. The access delay is calculated and the optimum reservation capacity threshold is derived to minimize that delay, for specific load conditions
