Abstract

A novel scheduling scheme for local area wavelength division multiplexing (WDM) single hop networks is introduced. The proposed protocol provides pre-transmission coordination schedule without collisions. It is based on a broadcast and select star architecture and uses a timeslot based access protocol. The proposed scheme incorporates a prediction based system, in order to reduce the amount of time spend in computing the schedule by predicting traffic requests. A series of simulation results is presented which indicates that when a specific schedule order is followed, starting from the node with the greatest demand, and completing to the node with the least demand (in transmission time) then a better network performance is achieved. Furthermore, the network throughput is higher, while the mean time packet delay at the waiting queues seems to be lower
