Wireless Time-Sensitive Networking Based on Distributed Clock Synchronization

Abstract

Based on Ethernet, time-sensitive networking (TSN) provides end-to-end data transmission with extremely low delay and high reliability. It is suitable for latency-sensitive applications and is widely used in autonomous driving, industrial Internet and other scenarios. This paper proposes a wireless TSN based on distributed synchronization, which can not only be used in real-time applications, but also be extended to satellite cluster networking applications. Firstly, this paper briefly introduces the main characteristics and application scenarios of TSN, and focuses on the time synchronization mechanism of wireless TSN. Then, a distributed clock synchronization algorithm suitable for wireless TSN is proposed and simulated. The results show that the algorithm can achieve sub-nanosecond time synchronization in 16 nodes wireless TSN, and the convergence time is seconds. At the end of the paper, the time synchronization performance of wireless TSN is compared when the number of network nodes and topology structures are different.
