Abstract:
Optical Code Division Multiple Access (OCDMA) is one promising candidate for the provision of moderate security communications with large dedicated bandwidth to each end user. We present a new teletraffic model for the call-level performance of an OCDMA Passive Optical Network(PON) configuration that accommodates multiple service-classes. Parameters related to the local blocking, Multiple Access Interference (MAI) and user activity are incorporated to our analysis, which is based on a two-dimensional Markov chain. In this paper we focus on the derivation of recursive formulas for the efficient calculation of blocking probabilities. To evaluate the proposed model, the analytical results are compared with simulation results to reveal that the model’s accuracy is quite satisfactory.
