On the Performance of Zenoh in Industrial Iot Scenarios

Abstract

Robust and efficient communication frameworks have become essential for the advancement of manufacturing and industrial processes in the era of Industry 4.0. This paper presents a comprehensive performance analysis of Zenoh, a promising protocol architecture for the IIoT. The analysis is conducted using a real testbed built with Raspberry Pi devices, comparing Zenoh's performance against the widely used MQTT protocol. The study evaluates Zenoh's capabilities in terms of latency, as well as its reliability and congestion control mechanisms over various network topologies, utilizing both TCP and UDP. The results indicate that Zenoh offers significant advantages in specific scenarios, making it a compelling choice for IIoT applications. Additionally, this paper contributes to a deeper understanding of Zenoh's underlying principles and its communication capabilities, positioning it as a versatile and efficient solution for modern industrial environments.
