A Novel Algorithm For Optimal Wavelength And Bandwidth Allotment In Ethernet Passive Optical Network

Ethernet Passive Optical Network (EPON) is that technology that can rule out the congestion in local loop at the level of user and local exchange. At present, there are many simulators to analyze the EPON but the simplest one is using MATLAB. In this paper, we have first analyzed the bit rate performance of WDM EPON and verified the result using NS2 software. After that in the presented WDM EPON model, we proposed an algorithm for wavelength and bandwidth allocation with full QoS support. The result indicates that traffic generation in both NS2 and MATLAB follow the same trend and the proposed algorithm optimizes the various throughput parameters. We found that the bit error rate varies from 14-22 Mbps, 14-55 Mbps, and 36-48 Mbps for EF, AF, and BE traffic respectively.
