95-733 Internet of Things Week 5

Topics

In week 5, two use cases are introduced, Sensor Andrew and OpenChirp. Both of these are IoT initiatives built at Carnegie Mellon. Sensor Andrew's use of XMPP is highlighted and so is OpenChirp's use of LoRa and LoRaWan.

We also discuss service discovery and the REST architectural style. CoAp is introduced as RESTful protocol and three Web of Things integration patterns are highlighted.

The Web of Things Architecture from W3C and Mozilla are introduced.

HTTP and CoAp are compared. It is noted that the microcontroller used in class interacts with the Particle cloud using CoAp.
