An analytical framework for distributed coordinated scheduling in IEEE 802.16 wireless mesh networks

We present an analytical framework for the delay analysis of the distributed coordinated scheduling in the IEEE 802.16 Wireless Network in mesh mode. We designed a queuing model that expresses the network limits accurately. The queuing model is of the type M/G/1/L developed using Linear Algebraic Queuing Theory. After modeling one node, an iterative method is used to calculate the traffic flowing in the whole network. With this model, it is possible to calculate the end-to-end delay and the throughput limit of the link layer. An algorithm is presented that applies a strategy to provide fair resource sharing. The numerical results and simulations for different topologies show that the model is accurate and that the fairness strategy effectively reduces the end-to-end delay.
