Web 3.0: user-generated networks?

21.01.2008
European researchers took the concepts of Web 2.0, like user-generated content and social networking, into the real world. They hope to create user-generated physical networks so internets could be set up, by anyone, anytime. It’s radical and, surprisingly, fairly realistic. Welcome to Web 3.0.

The internet, Web 1.0, is so incredibly powerful that even now, almost 20 years later, we have only begun to explore its potential. Web 2.0, with its YouTube, Facebook, Flickr and blogs galore is even younger and shows even more potential.

Now, thanks to the work of the WIP project, we may be on the brink of a new internet, a new world wide web. One where users can spontaneously create their own networks, in minutes, and with any kind of data device – mobile or fixed, handheld or deskbound. It means completely reinventing the internet, retooling its underlying technology, creating new operating principles and defining wholly new communications protocols so that it all works with any technology.

“When the internet first emerged, it assumed devices would be fixed in place and linked by wires,” remarks Marcelo Dias de Amorim, a researcher with the WIP project. “But that’s no longer true. A large number of devices are mobile and equipped with wireless communication capabilities.”

Many of the fundamental assumptions of the original internet have been superseded and many other pillars of the web are simply ad hoc (even bootstrap) solutions to discrete problems. It all appears rather accidental.

WIP wants to change all that, reinventing the internet and its underlying methods in what they cheerfully describe as disruptive technology. It is revolutionary, radical, but is it realistic?

DIY networking
“We’re not looking to replace the internet with the flick of a switch,” warns Dias de Amorim. “What we’re proposing is a robust, flexible, optimised and above all user-friendly set of technologies and standards that will mean any user, anywhere, can identify and network with any nearby devices. Without any technical expertise whatsoever.”

An example helps illustrate the concept. You live in an apartment building. You find neighbour’s wifi connections and invite them to join a new ‘building network’ with a few clicks. Now you can share and communicate with everyone.

You all have internet connections via an ISP, ranging from 1, 2 and 5 megabits/second (Mbits/s). You decide to pool your money and rent a fibre-optic line that handles voice, data and TV for the whole building. Suddenly you all have 10Mbit/s connections.

Another scenario. You go to a gig with some friends, set up an ad hoc network, and you can all communicate via text, voice or image for the rest of the day, all for free.

It’s a radical concept that must overcome some major design flaws of the current internet. One simple example: an IP address governs the routing of information and the identity of the recipient. “That works fine in wired networks, but what happens if the user moves. Their address has changed, not the identity,” reveals Dias de Amorim.

“But if separate values are used for identity and routing, then this isn’t a problem, even if the user is walking through a park. We’ve successfully separated the two functions.”

That is just one of dozens of challenges the WIP project has responded to during its research. It is a radical rethink of the current state of the art, but can it replace the internet?

“That’s not what we’re saying,” says Dias de Amorim. “It does address the basis of networking, but it can happily plug into the internet itself… That said, if everybody, or even the majority, is using WIP to create internets, then WIP is the internet!”

The project is not quite there yet, but it has made enormous progress. The project split the multitude of technical challenges into three grand strands: user applications and interface, routing protocols, and physical technology innovations. They fit hand in glove to allow users to set up the network, allow the protocols to communicate with any device, and allow the devices to keep up with requirements. It is plug-and-play networking for grown-up applications.

Remarkably, WIP is already in testing phase, using laboratories especially set up for the task, with many of the components of the system. Over the next year, it will finalise some elements and integrate them all together. Finally, it hopes to seed the technology in promising communities to kick-start its adoption.

And then we may see the beginnings of Web 3.0.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
