Abstract
A reservation-Aloha-like (R-Aloha-like) protocol is studied in a decentralized mobile radio network context, with some hypotheses and assumptions and under specific constraints. Periodical traffic with parameter sharing and local communications are special characteristics of the model. The studied system faced problems, such as hidden nodes, fast changes in the network topology, and intervehicle communications. To solve or reduce some of these problems, the R-BTMA MAC protocol is introduced. It uses two distinct physical channels: a data channel and a busy-tone channel for signaling. Simulations are presented to evaluate the R-BTMA performance. The main service considered is parameter sharing with a regular traffic: one packet per frame and per vehicle. Numerical results show the improvements in channel throughput. The reaccess delay is evaluated.<>
