Abstract
This paper presents an algorithm for Slotted-Ring Medium Access Protocol using in Wavelength Division Multiplexing Networks. The algorithm is based on the Tunable Transmitter - Tunable Receiver (TT-TR) approach, in which the transmitting node can send a packet over any wavelength and the receiving node can receive a packet from any wavelength. Moreover, the self-similar traffic distribution is used in the algorithm, for the purpose of better performance over long duration than short duration of the Poison distribution. In order to increase bandwidth efficiency, the Destination Stripping approach is used to mark the slot which has already reached the desired destination as an empty slot immediately at the destination node, so the slot does not need to go back to the source node to be marked as an empty slot as in the Source Stripping approach. From the simulation result, it is clear that the proposed algorithm overcomes higher network utilization and average throughput per node, and reduces the average queuing delay.
