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...

Rapid Development of Spreadsheet-based Web Mashups

The first talk of the day I decided to attend is from Woralak Kongdenfha from the University of South Wales, I had the chance to talk to Woralak yesterday about this concept of using Excel as a Mashup platform. I’ve been quite into (physical) mashups lately and I quite liked the idea since Excel is certainly a tool that people (at least from a business or IT field) massively understand. They probably understand it better than novel mashup editors such as Yahoo Pipes and co. Woralak starts by explaining that they devices to use Excel as a mashup platform exactly...

Remash! – Blueprints for RESTful Situational Web Applications 1

Remash! – Blueprints for RESTful Situational Web Applications

Remash! By Benjamin Blau, Steffen Lamparter and Steffen Haak, Steffen Haak is providing us with some blueprints for RESTful apps. He starts with a number of principles: 1) Resource oriented architectures -> services should expose data instead of functionality 2) Lightweight composition and flexible binding -> services should be re-composables 3) Mass collaboration, customization and perpetual beta -> ability to share the compositions. Steffen then explains how these principles were applied against a number of tools (e.g. Yahoo Pipes, etc.) to evaluate them. They identified three types of shortcomings: 1) Integration -> rather hard to integrate third-party services, not already...

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...

Using REST on SunSPOTs 3

Using REST on SunSPOTs

This post is the second in this series where we try to describe some of the concrete projects we are working on right now. The ultimate goal of the project was to create a smart logger that could be attached to shipments in order to monitor them while being transported or through their life-cycle, sort of a “ueber-RFID”. Of course, we wanted to use the REST principles in order to fully integrate the smart logger to the Web as well as to be able easily build applications on top of the logger. As smart loggers, we use the Sun SPOT...

David E. Culler, UC Berkley on RESTful Sensor Networks 0

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...
