In this paper, we propose a cross-layer scheduling scheme named DCLASA for the coordinated distributed scheduling of IEEE 802.16 WMN. This scheme considers the channel quality information (CQI) in physical layer when designing the timeslot allocation algorithm in MAC layer, and adjusts the node's holdoff exponent according to CQI. Meanwhile multi-user diversity and adaptive modulation and coding technique are adopted to improve system performance. Simulation shows that DCLASA can increase the network total throughput, and reduce link transmission delay.
