Scheduling Hybrid WDM/TDM Ethernet Passive Optical Networks Using Modified Stable Matching Algorithm

Hybrid wavelength division multiplexing/time division multiplexing (WDM/TDM) scheduling in multi-channel Ethernet passive optical networks (EPON) is gaining popularity compared to its only TDM or only WDM counterpart as they provide more flexibility, energy efficient load distribution and increased number of users and bandwidth support. In this paper, we have summarized the existing proposals for multi-channel EPON and proposed a novel scheme to further enhance the scheduling efficiency. For that purpose, a Modified Stable Matching Algorithm (MSMA) has been developed. We have also introduced a predictive just-in-time scheduling framework to dynamically evoke the MSMA in real time. We have provided extensive simulation results to prove the effectiveness of our proposed scheduling scheme compared to other existing schemes.
