HomeWeb and Android at Home – challenges?

As Google recently announced their plans to move in the home automation world with Android at home (and we are still wondering why they waited so long to do it), I thought I would share my view on that. I do believe there are many opportunities ahead for the “home operating system” domain. The combination of cheap, yet powerful networked digital appliances in the house (NAS, networked media players, WiFi routers, etc) along with an extensible application framework, and a market place for buying new applications (or installing drivers, etc) – will be a killer combo for home automation to...

IPv6 Day

You all know it (or should) we are soon running out of IPv4 addresses. Since we, the Web of Things community, pushing IP literally everywhere, feel a little bit guilty about it we wanted to show our support to today’s IPv6 world day!

Urban-IOT soon (and program ready) – join us in Tokyo!

We have been working hard to finalize the program of the Urban-IOT workshop that will take place very soon in Tokyo. In addition to a classic workshop with paper presentations and demos, we have prepared a second part, that will change your perception of what an academic workshop would look like. As we didn’t receive any industrial funding, we are sorry to say that we couldn’t afford to invite the people we had planned for a keynote (yeah, seems like industries aren’t interested in this topic… yet…). But no worries, we’ll use this time to hack and work! From 3...

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...

IP-based Sensor Networks

J.P. Vasseur from Cisco (IETF ROLL co-chair, IPSO tab chair) and Adam Dunkels have written a book on IP-based sensor networks called Interconnecting Smart Objects with IP – The Next Internet. The book covers IP-based sensor networks from the link layer and up, and covers network architecture (IPv6, transport, web services, …), technology (RPL routing, 6lowpan IPv6 802.15.4 adaptation, hardware, software, uIP,…), and applications (smart grid, industrial automation, home automation, smart cities, …). The foreword is written by Vint Cerf. The book will be available in June 2010, but is already available for preorder from amazon. This is great news...

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...

David Culler Part 2

David started with the introduction of the early visions for the internet of the future, with tons of real devices integrated to it. It was commonly argued that the classical OSI layers were to disappear in the area of WSN, because very optimized applications, fully customized for particular purpose were necessary. David argues that this view was wrong, because with recent IPv6 full stacks on devices (I’m thinking of the ones in TinyOs and Contiki) one could extend directly the Internet on devices, without requiring protocol translating bridges. Which rocks, coz gateways will become just routers. With this implemented, WSN...

David E. Culler, UC Berkley on RESTful Sensor Networks

Today, Vlad and I had the chance of taking part to a talk from David E. Culler from UC Berkley, one of the main TinyOS contributors. While Vlad is going to summarize the talk a bit later here, I’d like to talk a bit more about the end of the talk. One one of his slides he had a figure of what he would like to see implemented on WSNs at the node level. Besides a comprehensive IPV6lowpan (aka 6lowpan) stack he mentioned an implementation of HTTP and, moreover, a web server! The next slide was about sense making and...

Established in 2007, the Web of Things is a community of developers, researchers, and designers exploring the future of the physical Web. We want to leverage Web standards to interconnect all types of embedded devices and tagged products to make them easier to use and integrate in classic Web applications. WoT aims to build a future Web of devices that is truly open, flexible, and scalable, and we believe Web standards are the best way to do it.
