CHANNEL-ACCESS SCHEMES FOR DISTRIBUTED DIRECT-SEQUENCE NETWORKS
Arvind R. Raghavan · 1998
A multichannel reservation-based channel-access protocol is investigated in this paper. Under this protocol, one channel is used to exchange reservation messages and the remaining channels are used for information-bearing trajjic. The performance of this scheme is compared to that of a singlechannel reservation-based protocol. A simple contentionbased slotted-Aloha protocol is also considered. Performance results take into account the effects of distributed multipleaccess interference on acquisition and packet errors. Results show that the reservation-based approach is advantageous under conditions of high trafic.
