New codeword assignment strategy for optical CDMA networks and its performance analysis

A new codeword assignment strategy for OCDMA networks is proposed in this paper. Employing a new mathematical model, namely processor-sharing system, static-state throughput ratio and average delay of OCDMA networks are calculated. The results reveal that our strategy performs better than existing strategies. Meanwhile, analysis process is simplified compared with conventional Markov chain model, and corresponding results are indeed consistent with practical situation, thus processor-sharing system is truly applicable to model the OCDMA networks.EI0111970-19733
