The very big thing of the future

MANAGEMENT gurus are always discovering the next big thing (and source of income). Last year it was emerging markets and “frugal innovation”. This year it is “the internet of things”, or, as it has rapidly become “the internet of everything”.

Over the past decade billions of people have hooked themselves up to the internet via the computer and, more recently, mobile devices. This communication revolution is now extending to objects as well as people. Imagine if all the objects in the world had all the information that they needed to function optimally. Buildings would adjust themselves according to the temperature. Ovens would cook things for exactly the right time. The handles of umbrellas would glow when it was about to rain. We long ago inserted “intelligence” into objects in the form of thermostats and the like; the internet of everything will extend this principle exponentially, giving us unprecedented control over the objects that surround us.

The internet of everything will help solve two of the biggest problems facing the world: energy and health care. Buildings currently waste more energy than they use effectively. We will be able to cut this waste down to almost nothing. Health care is currently delivered in lumps: we visit the doctor a couple of times a year at most, and get our blood pressure checked every now and again. The internet of everything will allow us to monitor our bodily functionings all the time. A few sensors discreetly attached to the body will keep you constantly informed about how your vital functions are doing. It will also help us to keep ourselves healthy. Pill bottles will tell us when to take our medicines; wine glasses will be able to tell us when we have had enough to drink; sugar bowls will warn us about our sugar intake

Wiki for Contiki

The Contiki team announces the Contiki wiki, a wiki with documentation, getting-started guides, tutorials, a FAQ, and other information about Contiki! The Contiki wiki can be found at the following address:

New release , Contiki 2.5 !

Contiki is an open source operating system for wireless sensor networks and the Internet of things. Contiki provides low-power networking for resource constrained systems along with a development and simulation environment that makes research, development, and deployment easy. Contiki contains the low-power wireless Rime communication stack [3], the uIP TCP/IPv4 stack [1], and the IPv6 Ready certified uIPv6 TCP/IPv6 stack [4], complete with 802.15.4 6lowpan header compression and fragmentation.

The Instant Contiki development environment is a single-file download with all Contiki development and simulation tools [6].

Contiki 2.5 is a major update with many important new features. Release candidate 1 is released 3-4 weeks before 2.5 is released and is intended to help find showstopper bugs before the final 2.5 release. The code can be downloaded from the Contiki website.
New features in Contiki 2.5


ContikiRPL is an implementation of the proposed IETF standard RPL protocol for low-power IPv6 routing that now is the default IPv6 routing protocol in Contiki [5].

The ContikiMAC state-of-the-art low-power listening asynchronous radio duty cycling mechanism is now the default duty cycling mechanism in Contiki.
Contiki collect

Contiki collect is a CTP-like address-free data collection protocol that has been completely reworked to provide a significantly improved performance as well as configurability.

CollectView is a Java GUI that is used to set up a Contiki data collection network, either over Contiki collect or over UDP/IPv6/RPL.


Powertrace is an interface to the Contiki power profiling system that allows either real-time inspection or off-line analysis of the power consumption of a sensor network [2].

The MSPSim/Cooja simulation environment has received a significant speed-up.

Contiki 2.5 includes an experimental implementation of the IETF CoRE group’s CoAP application layer protocol for RESTful interaction with a low-power IP sensor network [7].

Résumé: Advances in low-cost embedded processors and wireless communications have fuelled the recent intense development of sensor networks, which has potential to offer unobtrusive and transparent personal and ambient sensing infrastructures that are vital to the creation of the envisioned ubiquitous computing fabric for ambient intelligence (AmI).

The continued miniaturization and integration of sensors at unprecedented scale and density into our everyday objects and environments would soon enable the fine-grain capture of personal and ambient context information that provides the basis of intelligence for higher-order cognitive systems, i.e. systems with the ability to perceive, reason, learn, and react intelligently to their environments in order to make the most appropriate decisions or to take the best actions that concern the humans at the centre of their support or care.

Following the success of the inaugural SeNAmI workshop in Dunedin, New Zealand in 2008, and the second SeNAmI workshop in Hiroshima, Japan, in 2009, this event once again aims to bring together researchers from academia and industry to present and discuss recent trends and advances in sensor networks and ambient intelligence, and from such engagement foster innovations towards technology maturity of sensor-based AmI systems and applications.

On Monday 31 may first day of summer school it was presenting :

* Mikael Wiberg from Umea University , Sweden about texture in Urban informatics. As that he was pointed out :
– texture & materiality : how we can create new textures ?
– culture of texture : From the “big apple ” to the “Screen City” Mikael Wiberg
– new texture in NY
– texture as composition
– texture a relational language

* Professor Anind Dey, Carnegie Mellon University, USA on Real World Context-aware systems
Growing pains with context systems are privacy, evaluation, error, development/end user support, Intelligent. <>.

* Adam Greenfield on Elements of a networked urbanism.

Shanmugalingam Sivasothy form Alcatel Paris shows quite extensively what was happening in Oulu in the first International Ubiquitous summer school.

Kiitos (Thanks in Finnish) to the UBI Summer School Program and UBI Challenge

Having a look in E-Workshop Dr. Zach Shelby on his official site is presenting his report .

1.Take a look on the MobySpray video I really enjoyed the idea.
2. Beej’s Guide a short networking programming guide
