Performance Analysis of Distributed Coordinated Scheduling in IEEE 802.16 Mesh Mode

In order to improve the scheduling efficiency of IEEE 802.16 mesh mode, exactly theoretical analysis is necessary. In the IEEE 802.16 mesh mode with distributed coordinated scheduling, all nodes are peers and multi-hop communication is allowed. Every node has to compete for transmission opportunities based on scheduling information in the two-hop neighborhood. In this paper, we use probability-based method to analyze the performance of network with different topology, different holdoff time and different node degree. The analysis and numerical results show how the three factors mentioned above affect the network throughput and delay.
