Melanie Swan has just had a paper published - Sensor Mania! The Internet of Things, Wearable Computing, Objective Metrics, and the Quantified Self 2.0 - which is a nice snapshot of the Internet of Things landscape and starts to dig into some of the underlying why and how of what IoT could provide.
It's also chock-full of useful links to relevant projects, platforms and solutions - including two I'm involved with: Bubblino and Good Night Lamp. That's why it's getting its own entry in the blog, rather than just a tweet, but it's worth a read aside from that!
