Network-coding-based multipath transmission in Software defined Fiber-Wireless networks

摘要

A network coding based multipath transmission scheme in Software defined Fiber-Wireless (SD-FiWi) networks is proposed in this paper. By exploring the broadcast nature of the passive optical networks and by activating the ability of optimizing the globe resources of SD-FiWi networks via powerful control, encoded packets can be transmitted through multiple paths via different Optical Network Units (ONUs) efficiently. Simulation results showed that the proposed scheme can effectively improve the goodput of SD-FiWi networks by fairly considering the batch size and the number of redundancy packets.
