LENA: An efficient channel eclectic algorithm for WDM optical networks

Media access control (MAC) protocols are methods and ways of accessing the optical fibers, in order to support communication to the nodes of the network. One of the important themes on the design of high-efficient optical networks is the time duration of the schedule process. A good protocol supports effective scheduling methods, without significant time cost. In this work, the performance of a new pre-transmission coordination based protocol on a wavelength division multiplexing (WDM) broadcast and select optical network is studied. A novel scheduling algorithm is proposed, which maintains a prediction scheme and concurrently constructs the pre-transmission scheduling form, based on the demanded traffic of each available channel. Also, this work includes the presentation of the new algorithm, the comparison of the new algorithm with two prior predicted scheduling schemes, along with the presentation and the description of a series of graphs, which plot the results of our simulation. According to simulation results, it is realized that the proposed algorithm not only improves the output of the network but also reduces the average time delay of the packets in the buffer memories of each node.
