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...

WOT Demonstration @ Pervasive 2009 1

WOT Demonstration @ Pervasive 2009

Dear all, A short paper I have been wanting to publish for a while here. It is about the Web of Things demonstrator we presented at Pervasive 2009 in Japan, which is based on our Energie Visible project. Since it is a short paper it does not present ground breaking results but it contains a bit more technical information on how the Plogg Gateway was built and on the resource orientation of the Ploggs. By the way, we finally managed to begin the deployment of the Energie Visible project in our own labs. The goal is to have Ploggs in...

Gateway unleashed! 1

Gateway unleashed!

I’ve presented yesterday in Los Angeles a talk on the gateways I’ve been talking about for months. Okay, actually I didn’t physically present it for logistical reasons, as I’m totally in Europe. But the paper is supposed to be out in the proceedings, so I thought I should share it with you. For now still not much code to play with 🙁 Read the abstract: Wireless Sensor Networks provide unprecedented possibilities for monitoring and interacting with the real-world. Unfortunately, the lack of open and simple standards for ad-hoc collaboration between heterogeneous embedded devices makes it difficult to build large-scale deployments;...

LOCA2009 – Selected talks series

Yep, that’s right, selected just for you! Oh forgot to tell you about the little present we got from IBM, a travel alarm clock and body fat analyzer in one! Never seen that combination in a single device yet (and this little jerk machine reminds me sadly that I should really do some more sports). Sadly no iphone/nike iPod connectivity yet 😉 Improving Location Fingerprinting through Motion Detection and Asynchronous Interval Labeling – Philipp Bolliger (ETH Zurich, CH); Kurt Partridge (PARC, US); Maurice Chu (PARC, US); Marc Langheinrich (University of Lugano (USI), CH) My ETH colleague Philipp Bolliger started with...

Towards the WOT Manifesto 6

Towards the WOT Manifesto

I’m taking a couple of days off in Romania, to chill out and reorganize my brain. We’ve been so busy working with Dom lately that we barely had time for WOT, and even less for getting our work done. Mainly tons of papers, meetings, talks, and barely no time to hack/code, and that kind of sucks. We both agreed that in the coming months, we’ll cut off random unproductive activities, to really focus on our work and building the Web of Things. I’ve notice that all the people I talk to not really understand what WOT is about, and for...

Towards the Web of Things: Web Mashups for Embedded Devices 2

Towards the Web of Things: Web Mashups for Embedded Devices

After having some troubles getting the Web of Things idea accepted by the scientific community it seems like the last weeks bring the wind of change 😉 The paper: “Towards the Web of Things: Web Mashups for Embedded Devices” we submitted a while ago to the MEM workshop of the WWW 2009 conference just got accepted. In this paper we better explain the concepts behind the Web of Things, namely we talk about the way we implement RESTful APIs for embedded devices. Furthermore, we discuss the different integration methods to connect embedded devices and sensor networks to the Web. Showing...

Ercim news

I wanted to blog about this for a while already. I’ve been waiting eagerly to read the latest issue of ERCIM news, which had for special theme “The Sensor Web“. Usually they have interesting articles on many cool high-tech topics, but I have to admit that this issue was quite disappointing for me. In particular, they talk about the Sensor Web, which has nothing to do with our WWW. There is not single mention of URI or HTTP or REST in the whole issue, but there are many articles that talk about the same approaches. I find this quite disappointing,...

Giving some REST to your C++ code: embedding the SHTTPD server. 1

Giving some REST to your C++ code: embedding the SHTTPD server.

Wanting to turn the Ploggs, into more RESTful devices, I needed to add a web server (HTTP) to the C++ code managing the Ploggs. After comparing and trying a number of lightweight web servers (Apache was not an option for this kind of small app) I picked SHTTPD, mainly because: It was one of the few I managed to embed in my C++ code (I’m not a C expert…) It offered the possibility of registering call back methods when a particular URL is called, which makes it a quite good candidate for a REST interface. Here is how I did...
