Providing integrated QoS control for IEEE 802.16 broadband wireless access systems

Abstract

This paper proposes a new integrated QoS architecture for IEEE 802.16 Broadband Wireless MAN in TDD mode. The current strategy of providing IntServ via IEEE802.16-2004 WirelessMAN is analyzed. A mapping rule for providing DiffServ between IP layer and MAC layer is given. A fast signaling mechanism is designed to provide cross layer integrated QoS for Point to Multi- Point (PMP) mode. Comparison between traditional RSVP signaling mechanism and proposed signaling mechanism is given. The simulation is conducted for VoIP, FTP and HTTP traffic. The results show that the proposed integrated QoS control mechanism can satisfy the bandwidth requirements of different applications.
