HYBRID ACCESS METHOD IN A MULTIPLE ACCESS CHANNEL.

Research output: Contribution to conferencePaperpeer-review

Abstract

A multiple-access communication channel with an infinite number of users is considered. It is shown that if a controlled slotted Aloha protocol is used, then messages with variable length will have a negative impact on the average message delay. In order to alleviate this problem a mixed mode (hybrid) access method is suggested under which the channel bandwidth is split into two subchannels, managed under different policies. Messages whose length is less than or equal to a critical value are transmitted in one subchannel under a slotted Aloha policy. The rest of the messages are sent through a separate portion of the channel bandwidth, using a reservation protocol. It is shown that under this hybrid access method the average delay of a message is greatly improved.
