Modelling multi-channel slotted ring networks with tunable transmitters and fixed receivers

This study presents a non-preemptive priority queue model to approximate the cell delay of a multi-channel slotted ring network with tunable transmitters and fixed receivers, and one queue for storing cells for each channel at each node. To analyze network performance, this network is translated to the proposed non-preemptive priority queue model. With this model, the approximated analytical cell delay results can be obtained by close-form formulas. This investigation assumes that the cell arrival rate for every destination at each node can be different and the number of nodes equals the number of channels. The accuracy of the model is assessed using the simulation results, and the two are found to be very close
