“…The three approaches are employed under different network packet traffic conditions. Also, the throughput performance of a single rate one-class OCDMA employing only the first class' parameters (class-1) of a multirate two-class 1-D MWML-OOC OCDMA network is evaluated in order to prove convergence between the proposed formalisms and the well-known single rate throughput formalisms [30], [32].…”

“…An expressive number of analytical approaches have been proposed to evaluating the packet throughput performance. However, all of them are limited to single service and single rate OCDMA networks, such as the approaches based respectively on Poisson [30], [31] and binomial [32]- [34] distributions to model the composite packet arrivals. On the other hand, a Markov chain approach was used in [35]- [40] to evaluate the packet throughput of single service and single rate networks.…”

In this paper, new analytical formalisms to evaluate the packet throughput of multiservice multirate slotted ALOHA optical code-division multiple-access (OCDMA) networks are proposed. The proposed formalisms can be successfully applied to 1-D and 2-D OCDMA networks with any number of user classes in the system. The bit error rate (BER) and packet correct probability expressions are derived, considering the multiple-access interference as binomially distributed. Packet throughput expressions, on the other hand, are derived considering Poisson, binomial, and Markov chain approaches for the composite packet arrivals distributions, with the latter defined as benchmark. A throughput performance evaluation is carried out for two distinct user code sequences separately, namely, 1-D and 2-D multiweight multilength optical orthogonal code (MWML-OOC). Numerical results show that the Poisson approach underestimates the throughput performance in unacceptable levels and incorrectly predicts the number of successfully received packets for most offered load values even in favorable conditions, such as for the 2-D MWML-OOC OCDMA network with a considerably large number of simultaneous users. On the other hand, the binomial approach proved to be more straightforward, computationally more efficient, and just as accurate as the Markov chain approach.

“…The BER convergence of the proposed multirate throughput formalisms towards that of the single rate formalisms can be guaranteed as long as the same set of parameters is adopted for the single rate network namely, = 1 = 600, = 1 = 4, = 1 = 36, and = 1 = 1024 bits. The throughput of the single rate OCDMA network versus the offered load based on the Poisson (dotted) [58] and binomial (dashed) [111] composite arrival distributions are plotted in Figure 4 In addition, the binomial-based results are more accurate than the Poisson-based ones when the offered load is sufficiently large (> 20 packets/slot). Therefore, this validation procedure confirms that the proposed multirate formalisms are indeed reliable and accurate.…”
