Standards for the Internet of Things Class 3: Communication Standards October 7, 2015 Louis W. Giokas

This Week’s Agenda Monday IoT Standards Overview Tuesday Device Standards Wednesday Communication Standards Thursday System Standards Friday Future Directions

Course Description The Internet of Things (IoT) is dynamic and growing by leaps and bounds. Standards will help in sustaining this growth. Standards are key to efficiently melding together many devices and systems from multiple vendors. The IoT consists of a multilayer architecture of devices and systems connected in complex networks. We will look at the types of standards developed, or being developed, by standards bodies, concentrating on the IEEE.

Overview The Internet of Things has three major parts: Internet Things Communications Back-end services Internet Much more than the WWW Global Internet Connected everywhere Local use of Internet Prorocol E.g., Industrial

Overview Standards Existing standards tend to be generic Need for IoT specific aspects IEEE lists many standards areas Wireless standards for low rate personal area networks Local and metropolitan area networks Power system signaling and Utility Industry metering Wireless Access in Vehicular Network (WAVE) Home networks

Internet Higher level open Internet protocols can be used in most cases Integration with cloud resources Industrial Internet needs to be deterministic Use the features of the IP to provide this Not generally directly connected to the public Internet Determinism concerns Safety and security concerns

Summary and Preview Today we have discussed communication standards and how they work together to create the IoT Standards determine how these systems are organized and interact with each other Next time we talk systems
