Abstract

The IEEE 802.16 mesh network is a promising next generation wireless backbone network. Under Coordinated Distributed Scheduling (CDS) mode, setting the holdoff time for nodes is essential to achieving good performances of medium access control layer scheduling in the networks. In this paper, we propose a dynamic scheme for setting holdoff time in IEEE 802.16 mesh mode with CDS. This scheme allows different nodes to use different holdoff time values according to Collision Intensity which is derived from Competing Neighbour Number and Collision Times of the current node. Simulation study shows how the dynamic scheme improves system performances evaluated in terms of throughput, end-to-end delay.
