The Network Of Everything: Personal Networks Will Have To Cope With At Least A Thousand Devices
ScienceDaily (Nov. 24, 2008) — Wireless experts believe that, by 2017, personal networks will have
to cope with at least a thousand devices, like laptops, telephones, mp3
players, games, sensors and other technology. To link these devices will
require a ‘Network of Everything’. It represents an astonishing challenge, but
European researchers believe that they are moving towards the solution.
European
researchers have just completed work on a networking project to perfect what
will become known, perhaps, as the Smart Personal Network. Personal Networks,
or PNs, are seen as essential for a world where many different devices must
work in sync together, known as 4G (fourth generation). It will mean
personalised services, low power devices with cheap, ubiquitous and broadband
connectivity.
The
EU-funded MAGNET Beyond project tackled all the issues surrounding PNs. MAGNET
stands for ‘My personal Adaptive Global NET’ and the project further developed
the concept of Personal Area Networks (PANs), first introduced in earlier PN
projects PACWOMAN and MAGNET.
While the
PANs link together all the devices and technology within a person’s reach, the
PNs spread the networking domain transparently towards the personal devices
reachable via different network infrastructures. A PN belongs to and serves a
private entity, a person, a fire fighter, or eventually a car, an aeroplane.
In the
future, there will be hundreds, even as many as a thousand devices in a PN. It
may seem an impossible figure, but in the near future the number of personal
devices will multiply enormously. One person might have dozens of sensors,
monitoring vital signs like heart rate and temperature, and even the electrolytes
present in perspiration. And then there are sensors and actuators in the home,
including light switches, and more again in cars.
People will
be able to link with TVs, stoves and spectacles, which could double as a
personal TV screen, and even clothing. They will have a home gateway, to manage
all their home devices, and a car gateway while driving.
A person
may access remotely personal files from almost anywhere in the world as if he
or she were at the office. People will be able to include others in their PN
and exchange personal information, or patch into a presentation in another
conference room and watch it remotely. Many of these technologies already
exist, but over time, they will become more widespread and connected.
In reality,
it is hard to know what kind of devices or technology might be around for sure,
but one thing is certain… there will be a lot of them. Hence the World Wireless
Research Forum’s (WWRF) prediction of 7 trillion devices for 7 billion people
by 2017 – in other words, around a thousand devices for every man, woman and
child on the planet.
“In the
industry, 2017 is like slang for a future where there will be many, many more
devices that people use in their day-to-day life,” explains Professor Liljana
Gavrilovska, Technical Manager of the MAGNET Beyond project. “This project
prepares for that future.”
Crossed-fingers
Right now,
PNs usually involve fiddling around with Bluetooth settings and crossing your
fingers. If it does work, users typically try to complete simple tasks by trial
and error, like hunting for photos on your mobile or trying to transfer a tune
from your computer to a PDA.
But in the
MAGNET model, users are able to easily set up their Personal Networks with all
their devices.
“We have a
user-centric approach,” reveals Gavrilovska, “with the overall objective to
design, develop, demonstrate and validate the concept of a flexible PN that
supports resource-efficient, robust, ubiquitous personal services in a secure,
heterogeneous networking environment for mobile users.”
In the
MAGNET Beyond vision, the devices will be self-organising and will be able to
form geographically distributed secure networks of personal devices. This
vision includes a platform for a multitude of personal applications and
services to support private and professional activities in an unobtrusive, but
dependable and trustworthy way.
United
federation of PNs
Better yet,
these networks will be able to ‘federate’ with other PNs on a permanent or
ad-hoc basis. Users will be able to link their PNs permanently with those of
their friends and family, or temporarily with other people and companies
depending on some purpose or joint interest (see photo 2). Users will be able
to control precisely what devices and information other people can link with.
Four
fundamental principles guided the consortium’s work: ease of use,
trustworthiness, ubiquity and low cost.
“For
example, the system is designed to be user friendly, with little or no training
required and no need for system administrators,” Gavrilovska explains. “It will
ensure security and protect privacy, and it will work everywhere, even without
any additional infrastructure, but still be able to exploit any available
resources, like wifi or cellphone networks, for example."
The key
elements to achieving these goals were personalisation and a tailored security,
privacy and trust framework, including identity and the management of
credentials. Credentials establish the trustworthiness of services outside the
PN.
Future-proof
“We also
designed it to be a future-proof architecture, to be self-organising,
self-managing and aware of the context,” Gavrilovska notes. The consortium even
developed new hardware prototypes with optimised air interfaces, to ensure the
MAGNET Beyond platform worked efficiently.
It was an
enormous challenge, but MAGNET Beyond enjoys substantial resources, too. The
consortium includes 35 companies from 16 countries on two continents. It has a
budget of over €16m, with €10.3m from the EU – and that is just phase two.
Phase one,
called simply MAGNET, had 32 partners in 17 countries on three continents with
a budget of €17.4m (€10m from the EU).
Both phases
featured many of the world’s leading corporations and research institutes, like
Nokia, NEC, Alcatel-Lucent, Samsung, TeliaSonera, Telefonica, CEA LETI, VTT,
CSEM, France telecom, Telefonica, Fraunhofer FOKUS, Delft University of
Technology, NICT, University of Surrey, Rome and Kassel, Aalborg, GET-INT, and
many others.
The effort
was worth it, with a vast range of innovative technologies now delivering Smart
Personal Networks. Personal Networks that can be easily integrated into the
future generations of wireless networks, and co-operate in the unfolding Future
Internet and Internet of Things.
The MAGNET
Beyond project received funding from the ICT strand of the Sixth Framework
Programme for research.
