How Do You Select Which IoT Protocol to Use? Vortragssprache Englisch

This session will cover a number of topics relevant to all IoT systems and presented because of the instructor's involvement with the IPSO Alliance and his understanding of the challenges in developing a system with IoT connectivity. The overriding goal of this session is to help prepare you to design your IoT system starting with the device, up to the Cloud and all the other components between them. Embedded systems using sensors and connectivity are not new to embedded developers. Using these elements with multiple additional Internet technologies is. This session describes the IP protocols dedicated to IoT because it helps shape the system capabilities. There are multiple IP Application Layer protocols, the ones above the TCP/IP sockets. Each one has its advantages and constraints. Knowing them helps make the best design choices for your product. Bandwidth requirements, real-time performance and memory footprint are some of the main criteria to use in selecting an IoT protocol. A large number of IoT projects are being driven by the CIO and the IT departments. The technologies and protocols known by the IT community are being pushed to IoT devices. But, these IoT devices often are closer to operational technologies (OTs) . In which too many cases, pushing IT technologies to OT domain is not a good choice. Unfortunately, the embedded community does not have the same media bandwidth as the IT community, meaning that developers need to be educated that there are better choices for IoT devices than IT technologies. There are multiple categories of IP protocols: - Consumer vs Industrial - Web services - IoT services - Publish/Subscribe - Request/Response. All these factors must be considered when designing a new system. This session will cover them and provide selection criteria. The last 15 minutes are used for a demo using a ST STM32F7 Discovery board, WiFi connectivity, a simulation of a smart home, MQTT and Amazon Web Services IoT. It is not a typical HTTP/Webserver examples. It is a lot more typical to what an IoT product should be for the industry to achieve the forecasted billions of deployed devices.
