Hi all,

I’m the newest contributor to WSNBLOG.com, so I thought I’d start out with a shameless plug for my own research. I’m working on integrating environmental sensors into cell phones. We’re doing a platform based on a bluetooth link to a phone, integrating into the battery compartment, with both off the shelf and bleeding edge sensors. We have some CO, NO2 and SO2 data we gathered in Ghana using an off the shelf datalogging solution this spring that we’ll publish shortly, and we have some cool algorithms that we’re about to publish as well.

The bleeding edge sensor is a MEMS particulate mass sensor which measures the change in frequency of a resonating FBAR as PM2.5 particles deposit on it via thermal phoresis. We will have the miniature prototype running this month (a larger prototype already works), and it will also integrate particle discrimination using IR and UV LED based interferometry.

The algorithmic research focuses on super-sampling for higher sensing precision, automatic calibration, and later work will include plume detection and context inference.

Check out the web site if you’re interested, and I’ll give some more details soon!

Save the date - January 22-24, 2008. Sun will be hosting the first Java Mobile & Embedded Developer Days Conference at our Santa Clara, CA campus - an event dedicated to mobile and embedded Java technologies and applications.

The Call for Papers is now open and will end October 31, 2007.

This is your chance to participate! Submit a session abstract, grab a few friends & suggest a panel discussion, consider showcasing a cool application or just plan to come & participate as an audience member.

Content areas are expected to be centered around JavaME, and open source aspects of the Mobile & Embedded Community - including traditional phone and PDA development on the Java ME platform as well as SunSPOT wireless sensors, Trackbot and Java robotics, and other small Java software-based systems & applications.

But the actual sessions will really be based on the submissions & participation from the Java developer community.

The clock is ticking - check out the Conference site for more information.

Considering a wireless sensor network whose nodes are distributed randomly over a given area, a probability model for the network lifetime is provided. Using this model and assuming that packet generation follows a Poisson distribution, an analytical expression for the complementary cumulative density function (CCDF) of the lifetime is obtained. Using this CCDF, one can accurately find the probability that the network achieves a given lifetime. It is also shown that when the number of sensors, N, is large, with an error exponentially decaying with N, one can predict whether or not a certain lifetime can be achieved. The results of this work are obtained for both multi-hop and single-hop wireless sensor networks and are verified with computer simulation. The approaches of this paper are shown to be applicable to other packet generation models and the effect of the area shape is also investigated.
