光纤无线（Fiber Wireless，FiWi）网络通过将光网络和无线网络相结合，能够提供宽带和灵活的通信。为了减少站（STA）和光网络单元（ONU）的能量消耗，在光网络和无线网络中存在若干功率节省机制。通常，功率节省机制导致延迟。在FiWi网络中，延迟问题变得更加关键，其中同时使用多个功率节省机制以减少能量消耗。在本文中，我们分析的延迟，通过考虑之间的关系的省电机制，独立控制的STA和ONU在FiWi网络，并指出的问题，两个延迟可能会同时发生。为了解决这个问题，我们提出了一种新的节能机制的STA，它控制的STA同步两个节能机制的ONU和STA。通过数学分析和数值计算，我们证实，所提出的方法可以显着降低能耗，而不会增加任何延迟。
By combining optical networks and wireless networks, Fiber Wireless (FiWi) networks are able to provide broadband and flexible communication. In order to reduce energy consumption of STAtions (STAs) and Optical Network Units (ONUs), there are several power saving mechanisms in optical networks and wireless networks. Generally, power saving mechanisms lead to delay. The delay problem becomes more critical in FiWi networks where multiple power saving mechanisms are used at the same time to reduce energy consumption. In this paper, we analyze the delay by considering the relationship between the power saving mechanisms, which independently control the STAs and the ONUs in FiWi networks, and point out the problem that two delays can occur at the same time. In order to address the problem, we propose a novel power saving mechanism of STAs, which controls the STAs by synchronizing two power saving mechanisms for ONUs and STAs. Through mathematical analysis and numerical evaluation, we confirm that the proposed method can significantly reduce energy consumption without any increase in latency.
