Abstract :
In this paper, we propose a dynamic approach for transmission holdoff time in IEEE 802.16 mesh mode with Coordinated Distributed Scheduling scheme (C-DSCH). This scheme allows different nodes to use different holdoff time values according to current node need of the control-plane bandwidth. Nodes that need to establish data scheduling use small XmtHoldoffExp, while others use large XmtHoldoffExp. Simulation results show that the proposed dynamic approach can reduce unnecessary transmission delays and improve network throughput.
