How Do the Multiple Tunable Receivers Per Node Affect the Efficiency of a WDM LAN? A Performance Analytical Study
In this study, the performance of a WDM LAN of passive star topology is explored. An effective synchronous transmission WDMA protocol is proposed that employs a pre-transmission reservation scheme in order to improve the system output. Each station is equipped with a network interface with more than one tunable receivers in order to be able to receive more than one data packets during a time frame. As a results, the average probability of packet rejection at destination is significantly reduced as compared with the single tunable receiver per station case. The system performance is mathematically modelled based on Poisson statistics and finite station population. Also, an analytical framework is adopted to evaluate the effect of the number of tunable receivers per station on the total performance. Numerical results are comparatively studied for various numbers of data channels and stations. Finally, the propagation delay latency parameter is properly modelled while its impact on the system performance is analytically evaluated.
