摘要

工厂自动化中实时通信基础设施的当前目标是合并和平衡两个世界的最佳，即有线网络的可靠性和无线技术的灵活性。为建立工厂自动化实时通信基础设施，提出了有线-无线混合网络。然而，同步时钟的供应通常被认为是理所当然的，而关于有线和无线同步集成的问题被忽视了。在本研究中，研究了以IEEE 1588为期望同步协议的基于IEEE 802.11 wlan的混合网络为此类网络提供时钟同步的需求。本文还给出了基于wlan的混合网络同步性能的仿真和实现结果。

Clock synchronization for IEEE 802.11 based wired-wireless hybrid networks using PTP

The current goal for real-time communication infrastructure in factory automation is to merge and balance the best of both worlds, i. e. the reliability of wired networks, and the flexibility of wireless technologies. Hybrid wired-wireless networks are proposed for establishing real-time communication infrastructures in factory automation. However, the provisioning of synchronized clocks is often taken for granted, and issues regarding the integration of wired and wireless synchronization are neglected. In this study, the requirements for providing clock synchronization for such networks are investigated for an IEEE 802.11 WLAN-based hybrid network with IEEE 1588 as the desired synchronization protocol. The paper also presents simulation and implementation results to assess the synchronization performance of WLAN-based hybrid networks.
