SuperMAN: Optical-wireless integration of RPR and WiMAX

Abstract

This paper introduces a novel fiber-wireless (FiWi) network architecture, called SuperMAN, and investigates the optical-wireless integration of a resilient packet ring (RPR) and WiMAX networks. We propose a novel hierarchical integrated scheduling algorithm that significantly improves the throughput-delay performance and triple-play quality-of-service support for fixed and mobile users. By means of extensive simulations we show in a benchmark comparison that the proposed hierarchical scheduler clearly outperforms the widely deployed weighted fair queuing (WFQ) scheduler in terms of mean aggregate throughput and mean delay as well as robustness for voice, video, and data traffic under realistic wireless channel conditions.
