IoT’s Communication Technologies, Data Formats, and Protocols - A survey

The efficient implementation of the Internet of Things (IoT) depends on the identification of the resources, representation of the measured values in a suitable format, efficient communication among resource-constrained things, and analysis adopted. In this paper different data formats, protocols, and new data specifications are explored. Protocols at different layers of IoT architectures are analyzed, compared and findings are represented. The study provides the user the knowledge to adopt technology to their need and implement IoT effectively.
