This paper presents and discusses a new network environment, which combined conventional Ethernet with WDM to decrease the average queuing delay and increase the normalized throughput over different network configuration. The performances of Ethernet/WDM network operating over different number of wavelength channels are evaluated with different network parameters using discrete event simulator called OMNeT++. The study shows that Ethernet/WDM gives a higher normalized throughput and less delay compare to the standard Ethernet network. In this paper also we present the result of performance evaluation of 3 algorithms that combine CSMA/CD and WDM- sort increasing (SI), random select (RS) and no back off (NB) access protocol. Through extensive network-level simulation for a multiple-access WDM/Ethernet, with 3 nodes and 1, 2 and 3 wavelengths on a 100 m fiber optic cable, we have verified that RS and SI show the best performance in term of throughput, while for the delay, NB shows the best performance.","PeriodicalId":239300,"journal":{"name":"Proceedings.

The objective of feature selection and extraction is to speed up the NN training process and to achieve a more accurate NN results. The proposed method is known as the SDFT method in which it is a combination of the sensitivity and discrete Fourier transform methods. The sensitivity analysis is first used in selecting the input features and then followed by the discrete Fourier transform (DFT) method for extracting NN input features. The hypothesis set of pre-selected data performed by the sensitivity method only offers no improvement in the NN training performance in such cases where many features are highly correlated. Thus, the DFT method is considered so as to extract the pre-selected data to a set of meaningful extracted data. To illustrate the effectiveness of the proposed method, a comparative study of the SDFT, DFT and sensitivity methods is made so as to investigate the effectiveness of the methods in extracting and selecting the NN features. In this study, the NN based available transfer capability assessment has been performed on the Malaysian power system.","PeriodicalId":239300,"journal":{"name":"Proceedings.
