A Review on Communication Protocols of Industrial Internet of Things

The Industrial IoT (IIoT) system enables the industries to gather and evaluate massive amounts of data, which can then be utilized, legalized, and improved to provide new sorts of services. This survey discusses the most recent cutting-edge research initiatives in IIoT. Surprisingly, the study, which includes architecture of IIoT, communication protocols, and frameworks, is described in depth. The primary aim of this survey is to examine the various communication protocols utilized in IIoT and its applications. The ideas of IIoT, IoT, and Industry 4.0 are analyzed and compared in this analysis. This study discusses several communication protocols used in IIoT, such as HTTP, MQTT, CoAP, XMPP, AMQP, and MODBUS. On the basis of assuring dependability, these techniques may enhance lifetime and shorten delay. The implementation of protocols based on network topology, as well as their computational and latency performances are analyzed and compared. These protocols are utilized in IIoT for various scenarios in many areas based on the applications and communication networks. The IIoT is addressed in this paper, which can assist researchers to comprehend the idea of IIoT and the latest research activities in IIoT. At last, the protocols utilized in IIoT communication are highlighted.
