摘要：

A reservation multiple-access (MA) 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 slotted-ALOHA-type reservation channel 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 the ALOHA-reservation protocols, both proposed for satellite communications, or the PRMA, an R-ALOHA-type MA 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. © 1990, IEEE
