Abstract :
A multichannel reservation-based channel-access protocol is investigated. Under this protocol, one channel is used to exchange reservation messages and the remaining channels are used for information-bearing traffic. The performance of this scheme is compared to that of a single-channel reservation-based protocol. A simple contention-based slotted-Aloha protocol as also considered. Performance results take into account the effects of distributed multiple-access interference on acquisition and packet errors. The results show that the reservation-based approach is advantageous under conditions of high traffic
