COAP-01 draft out!

After the last draft released in december, the COAP folks just released a few days ago a more refined version of the COAP draft, with additional thoughts on coap-http mapping, RESTful verbs for constrained environments, and pub/sub notifications, and more. Abstract This document specifies the Constrained Application Protocol (CoAP), a specialized RESTful transfer protocol for use with constrained networks and nodes for machine-to-machine applications such as smart energy and building automation. These constrained nodes often have 8-bit microcontrollers with small amounts of ROM and RAM, while networks such as 6LoWPAN often have high packet error rates and a typical throughput...

COAP draft available!

Fresh out of the box, COAP draft is available since ahem… a couple of hours (self-pride for my timing as you can notice). This is definitely for me, us, and you all a definite pace for mankind – a solid and viable proof that the WoT is coming, and a very nice Christmas present. What is COAP I hear you saying? From the draft: The use of web services on the Internet has become ubiquitous in most applications, and depends on the basic REST architecture of the web. The proposed Constrained RESTful Environments (CoRE) working group aims at extending the...

Node.js, GPIO and the Raspberry Pi

http://ice-station.com.mx This post is an excerpt of the Chapter 4 “Getting Started with Embedded Systems” in Building the Web of Things, a Manning book by Dominique Guinard and Vlad Trifa. In a previous post we talked about the increasing importance of Node.js for embedded systems in the IoT but we didn’t have a concrete look at what using Node.js on an embedded device looked like. In this post we’ll look at what it means for the Raspberry Pi. Installing Node.js on a Raspberry Pi The first step is to install Node on your Pi. The latest versions of Raspbian (the...

WoT 2016: Seventh International Workshop on the Web of Things

It’s our pleasure to announce the WoT 2016, the seventh edition of the international workshop on the Web of Things. WoT was the first workshop on the topic and where much of the WoT was born, it bootstrapped the community and is definitely the place where WoT researchers and practitioners meet. We look forward to receiving your paper submissions until September 19 and to meeting many of you there! CALL FOR PAPERS – Seventh International Workshop on the Web of Things (WoT 2016) Held in conjunction with IoT 2016, Stuttgart, Germany, November 7-9, 2016. Official workshop site: https://webofthings.org/events/wot/wot2016/ Abstract Continuing...

Building the Web of Things Book is Out!

December 1oth, 2014 Vlad and I signed a contract with Manning Publications for a book on the Web of Things, a year and 8 month later, we are thrilled to announce that Building the Web of Things is out! We learned the hard way that writing a book is not as trivial as it seems. “Oh, we’ll just refresh our PhD theses and we’re done in a few weeks” has gradually turned into “OK, well, I guess we’ll have to write these chapters from scratch over the next few months. What about the source code? Which source code? Let’s just...

What’s in HTTP/2 for the Internet of Things? 1/2

If you followed this blog you probably know that the motto of the Web of Things community is to re-use Web protocols to build a truly interoperable Application Layer for the Internet of Things. One of the key protocols we are talking about is HTTP currently massively deployed on the Web in its 1.1 version. HTTP/1.1 is a great protocol when used correctly to build Web Services as illustrated in this book! However, it dates back from 1999. Remember this time? Back then we were using Windows 95, wired phones to call each other and the IoT term had just...

The Web of Things has a Book!

In 2007, Vlad and I were working at SAP Research on a European project called “SOCRADES” (disclaimer: vintage video content inside, remember this was 2007 :)). The goal of that project was to create a service layer for the Internet of Things. In short it was all about integrating real-world Things to applications so that the media gap between, say, real-world sensors and ERP applications would be drastically reduced. The idea was sound, really sound. The approach we used much less… We started looking at WS-* (aka big Web Services, or SOAP WS) services and pushing them down to devices....

First WoT W3C Interest Group Face to Face Meeting

Note: although this is a summary of the ideas and discussions I was involved in at the WoT W3C IG meeting these are my views and they may not necessarily reflect the views of the W3C WoT IG. A couple of weeks ago we had the chance to participate to the first face to face meeting of the W3C WoT (Web of Things) Interest Group (IG). We were reporting a little while back about the foundation of this group which was officially kicked off recently with a first face 2 face meeting that took place in Munich. This group is...
