Contention-Free Distributed Dynamic Reservation
MAC Protocol with Deterministic Scheduling
(C-FD3R MAC) for Wireless ATM Networks
Chung Gu Kang, Member, IEEE, Chang Wook Ahn, Kyung Hun Jang, and Woo Sik Kang
Abstract--This paper proposes a novel MAC protocol for wire-
less ATM networks, which is characterized by a contention-free
mechanism of the reservation request and a deterministic na-
ture of mobile-assisted (distributed) uplink scheduling under a
framework of the dynamic reservation TDMA, as discussed in
the current standardization activities of ETSI Project BRAN
(broadband radio access network) and the wireless ATM working
group in the ATM Forum. The design objective of the proposed
MAC protocol is to guarantee the real-time constraint of real-time
VBR (rt-VBR) traffic class while maximizing the multiplexing gain
among all ATM traffic classes, especially with a fixed length frame.
The proposed deterministic scheduling scheme for the rt-VBR
traffic class lends itself to implementing the minimal configuration
of control data units for reservation request as desired under
the limited wireless resources. Simulation experiments using
