Abstract

The IEEE802.16 (WiMAX) standard specifies the air interface of broad width access systems. Mesh topology is supported as an optional structure. In the mesh network, coordinated distributed scheduling is an important scheduling mode. Such mode permits traffic to be routed through other subscriber stations (SS) and occur directly between SSs. Xmt holdoff exponent is an import parameter in the mode. How to set it makes a great impact on the whole scheduling performance. In this paper, a dynamic setting scheme based on classification is proposed and compares in performance with the static scheme with fixed values. Simulation results show the proposed scheme can increase throughout and can provide different quality of service (QoS) levels for multimedia services.
