Wireless Precision Time Protocol
Ayush Garg, Akash Yadav, Axel Sikora, Ashok Singh Sairam · IEEE Communications Letters · 2017
The IEEE 1588 precision time protocol (PTP) is a time synchronization protocol with sub-microsecond precision primarily designed for wired networks. In this letter, we propose wireless precision time protocol (WPTP) as an extension to PTP for multi-hop wireless networks. WPTP significantly reduces the convergence time and the number of packets required for synchronization without compromising on the synchronization accuracy.
