Asymmetric access rights algorithm for performance improvement in WDM LANs

A wavelength division multiplexing local area network with a separate control channel is considered in this paper. Key point of the study is the access rights over the WDM data channels in order to enhance the performance. Thus, an efficient access scheme that provides asymmetric rights to all the stations is proposed. Particularly, a synchronous transmission WDMA access algorithm is introduced that achieves to improve the probability of successful transmission over the data channels. An analytical Markovian model is studied while the performance measures are mathematically derived. The performance is studied for several numbers of data channels and various values of control phase duration.
