EWSN Tutorial: Computing in the Real World with Java

Speaker: Joe Polastre, Sentilla ltd. (USA)

Abstract: Pervasive Computing is about making the real world — and everything in it — smarter, through the use of small, wireless, battery-powered computers (often called “motes”) that can be put anywhere or attached to anything. By moving beyond wireless sensing to a full computing environment, pervasive applications can revolutionize the way we live, work, and play. Conventional wisdom asserts that low-power resource-constrained systems are incapable of running fully featured computing environments, such as Java. This talk shows the basic architecture of a pervasive computer, a Java Micro Edition (JavaME) platform extended to pervasive computing by Sentilla, and techniques for developing and debugging applications distributed across large numbers of pervasive computers.

WSN in China

The December 2007 issue of IEEE Wireless Communications features an interesting paper on “China’s national research project on wireless sensor networks”, by Ni, L.M.; Liu, Y.; Zhu, Y. It describes the National 973 project in China that was launched in September 2006.

You can visit the program’s homepage at They have also released a sensor network OS called Senspire. These pages are all in Chinese, no English version yet.

An interesting blog on WNS with entries about applications in China is Weiwei’s Study blog.

From 7.5th floor:

Data management in the worldwide sensor web draws the big picture in mentioning that now too much attention has been placed on the networking issues of distributed sensing and too little on tools to manage, analyze and understand the data. The authors ask the question weather we can design sensor networks with data quality in mind? They ask a very crucial question, but as often in location-aware computing, it is very unclear on who can claim what quality in location information is or in other words who can answer “how good is good enough?”. Of course it is important to manage temporal and spatial data and handle their inherent uncertainty (e.g. via probabilistic theory) or mask it (e.g. via interpolation) or play with it (seamful design). It seems clear now that my thesis is about acknowledging that situation (uncertainty in the location information, fluctuant quality in the data), but instead of aiming to produce “perfect data”, I plan to provide an understanding and solutions from a human and urban perspective. It comes, at the first place, with the observation of people experiencing location-aware systems in CatchBob!, and making use of location information, in my taxi driver (co-evolution, context and granularity). This observations help me accumulating evidences on the contextual factors influencing the granularity (≈human expectation of quality) of the location information used.

Mannasim WSN simulation environment

The Mannasim Framework is a module for WSN simulation based on theNetwork Simulator (NS-2). Mannasim extends NS-2 introducing new modules for design, development and analysis of different WSN applications.

Mannasim is a Wireless Sensor Networks simulation environment comprised of two solutions:

the Mannasim Framework;
the Script Generator Tool.

The Script Generator Tool (SGT) is a front-end for TCL simulation scripts easy creation. SGT comes blunded with Mannasim Framework and it’s written in pure Java making it plataform independent.

PhD-NOW workshop

The PhD-NOW workshop, following the success of PhD sessions at the senZations’06 and senZations’07 summer schools aims to provide a friendly and supportive atmosphere where PhD students can present their ongoing research for an open discussion, get constructive feedback and learn what problems are being tackled by the fellow students. More importantly, it also provides a venue for all participants to “network” with their peers and established networks researchers, obtain valuable guidance tips and participate in a forum designed specifically to benefit graduate students. We particularly encourage PhD students from the EU convergence regions and Western Balkan countries to take part in the workshop.

The PhD workshop will be a one-day, seminar-style event, consisting of short presentations followed by roundtable discussions. Time will be allotted to each student for the presentation, and for the following in-depth consideration and discussion.

Fifth International TinyOS Technology Exchange

The next TinyOS Tech Exchange will be held on Feb. 22 at UC Berkeley in Sibley Auditorium.

It will continue the tradition of providing a forum for researchers, developers, educators, companies, and users to learn from one another about important recent developments within the TinyOS embedded network systems area and to participate in shaping paths of future development.

This year there will be in-depth presentations from the working groups, in addition to the community demonstrations and topical panels.

More details to follow soon.

Call For Papers – WSAN 2008
