A New Strategy for Providing QoS in IEEE 802.16 Standard

This article presents a new QoS architecture for IEEE 802.16 Broadband Wireless MAN. The newly proposed strategy of providing QoS in packet-based networks via IEEE 802.16 has been analyzed. A mapping rule for providing layer 2.5(MPLS protocol) and MAC layer has been proposed. A fast signaling mechanism has been designed to provide QoS in Point to Multipoint (PMP) mode. Although IEEE 802.16 standards define different mechanisms to provide Quality of Service requirements, it is the responsibility of the developers to obtain efficient designs. In this paper, we introduce a novel architecture for providing QoS requirements such as bandwidth utilization and delay. Simulation result shows the high performance of our architecture for traffic classes defined by the standard.
