Research plan for Pervasive 2009

Folks, I’m currently drafting my final research plan for my phd based on the input I got from various sources (thanks to all who helped me with that). That reminds me that I actually went to Japan to publish my initial research plan, and as it’s under press anyway, I put it here so that you can read all read it (and YES, give me more feedback about it). Of course, the current one is so much better (and I’m soo modest), but anyway it contains some scientific basis of my current research so that you have a better idea...

What Exactly is the R in Resource-Oriented-Architectures? 2

What Exactly is the R in Resource-Oriented-Architectures?

As all of you know, one of the core concept of the Web of Things is design of RESTful things, that is having embedded devices proposing their services in a Resource-Oriented manner. Today, once again, somebody was asking me but what is exactly a resource? Well good question! We all know (hem) what an Object is in Object Oriented Programming, we all know (hem HEM, yeah right!) what a service is in Service Oriented Architectures but what is a resource in a ROA? I had this discussion with a good friend of mine (and a very good OO architect!) let’s...

WoT keynote (and clones :) 3

WoT keynote (and clones :)

I never know if I need to be happy or sad when I see other people mentioning WoT. Don’t get me wrong: I’m totally happy to see people pushing forward the same ideas we have here, make them better, build upon them and reuse them for their own projects. One year ago, most people I talked to were like “aha, use web on devices…. but why? Why not use something made for devices?”. It didn’t sound right at that time, but when you think about a world of web enabled devices, then you can see tons of bulbs turning on....

Talk at UNI lugano

A couple of weeks back, we gave a talk with Dom at the University of Lugano. Besides, being a lovely cosy university in a wonderful place, we had a great time discussing with Cesare Pautasso and his colleague Francesco Lelli, a physicist working at CERN and Uni. Lugano. We had an interesting discussion with Francesco, who is specialized in grid computing, and he told us how they have used REST at CERN. The main ideas are summarized in these papers: [1] F. Lelli and C. Pautasso The Tiny Instrument Element Project In proc of 4th International Conference on Grid and...

Web Enablement of Sensor Networks: INSS 2009 6

Web Enablement of Sensor Networks: INSS 2009

Dear folks, People have been asking for more “scientific” and concrete material to be posted on WOT. Hence this post which is about a paper that we got accepted for INSS 2009 here is a summary of what it talks about: Wireless Sensor Networks (WSNs) have promising industrial applications, since they reduce the gap between traditional enterprise systems and the real world. However, every particular application requires complex integration work, and therefore technical expertise, effort and time which prevents users from creating small tactical, ad-hoc applications using sensor networks. Following the success of Web 2.0  “mashups”, we propose a similar...

Why is the Web Loosely Coupled? A Multi-Faceted Metric for Service Design 0

Why is the Web Loosely Coupled? A Multi-Faceted Metric for Service Design

Why is the Web Loosely Coupled? A Multi-Faceted Metric for Service Design by Cesare Pautasso and Erik Wilde. Dom: Just for the records, I have to admit that this paper is clearly amongst my top five for 2009. It’s a paper we can use and cite quite a lot in frame of our web of things projects in order to justify our design choices. Cesare begins by asking the audience whether WSDL is loosely-coupled? Most people said no which kind of crashed Cesare’s effect (Dom: I guess many people like me pre-read the paper ;-)). Some aspects of WSDL go...

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...

Energie Visible: A Video 7

Energie Visible: A Video

I’m pretty sure that by now you got the fact that the Energie Visible project is one of our favorite use-cases for the Web of Things. In this project we apply the concept of smart things with webservers and RESTful APIs to create a plug-and-play energy monitoring system for your home or company. In order to better illustrate the application and for us not to have to carry a printer, a kettle and a… fridge around for each demo, we shot a video of the prototype. The end of the video also contains some more technical insights on the structure...

Ercim news 1

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,...

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...
