Abstract :
This paper proposes a new integrated QoS architecture for IEEE 802.16 broadband wireless MAN in TDD mode. After analyzing the current strategies to provide IntServ for the Internet connection via IEEE802.16-2004 WirelessMAN, a mapping rule and a fast signaling mechanism for providing both InterServ and DiffServ are given under point to multi-point (PMP) and mesh mode. Comparison and performance analysis of traditional and proposed signaling mechanism are given. The simulation is conducted for VoIP, FTP and HTTP traffic with different QoS requirements. The results show that the proposed integrated QoS control mechanism is more fast and efficient for service setup and maintenance. What is more, bandwidth requirements of different applications can be satisfied by the proposed architecture
