Abstract

This paper presents a performance analysis of SPE-OCDMA (spectrally phase-encoded optical CDMA) over WDM networks. The discrete time Markov chain model is used to build analytical model of multi-channel random access slotted Aloha. The number of WDM wavelength is corresponded to multi-channel slotted Aloha. We measure several performance characteristics, namely, steady-state throughput and average packet delay time. Additionally, the efficiencies of the system, which are based on both the processing gain and the number of WDM wavelengths, are considered. Additionally, exponential retransmission is used for solving packet collision problems. In our numerical results, system performance is given in terms of both average throughput and delay time.
