An earthquake engineer at Washington University in St. Louis has successfully performed the first test of wireless sensors in the simulated structural control of a model laboratory building.
Shirley J. Dyke, Ph.D., the Edward C. Dicke Professor of Civil Engineering and director of the Washington University Structural Control and Earthquake Engineering Laboratory, combined the wireless sensors with special controls called magnetorheological dampers to limit damage from a simulated earthquake load.
Her demonstration is the first step toward implementing wireless sensors for structural control in real buildings and structures, enabling less manpower requirements and far less remodeling of existing structures.

Interested in real world experiments or deployments of wireless sensor networks? Then ACM RealWSN is the event for you. This year RealWSN will be held in conjunction with ACM EuroSys 2008 (Glasgow, Scotland, April 1, 2008). We expect to attract lively participation from the EuroSys systems community. Last RealWSN event was held with ACM MobiSys in 2006. Authors are invited to submit papers (5 pages, double column) for
presentation at the workshop. Submissions are due on 10 February, 2008. More details here.
Finally a book on Wireless Sensor Networks that covers real world applications and contains practical advice!
Kuorilehto et al. have written the first practical guide to wireless sensor networks. The authors draw on their experience in the development and field-testing of autonomous wireless sensor networks (WSNs) to offer a comprehensive reference on fundamentals, practical matters, limitations and solutions of this fast moving research area.
Ultra Low Energy Wireless Sensor Networks in Practice:
- Explains the essential problems and issues in real wireless sensor networks, and analyzes the most promising solutions.
– Provides a comprehensive guide to applications, functionality, protocols, and algorithms for WSNs.
– Offers practical experiences from new applications and their field-testing, including several deployed networks.
– Includes simulations and physical measurements for energy consumption, bit rate, latency, memory, and lifetime.
– Covers embedded resource-limited operating systems, middleware and application software.
Ultra Low Energy Wireless Sensor Networks in Practice will prove essential reading for Research Scientists, advanced students in Networking, Electrical Engineering and Computer Science as well as Product Managers and Design Engineers.

The Matrix trilogy was one long paean to data visualization. As we all know, it began with the premise that life was a sophisticated simulation, virtual reality taken to the civilizational level. Except for a few Matrix die-hards that I’m sure exist, people don’t actually believe this is what the physical/geographical world actually is. But with new sensor technology, we could create the datasets that the movies hinted lay inside the world. Current efforts at revisualizing the world through specific environmental data collection — traffic flowmaps, real-time temperature maps — will expand into a much wider variety of fields over the next few years.

The Int’l Networking and Communications Conference (INCC) 2008 will be held in Lahore, Pakistan from May 1-4, 2008. Pakistan is amongst the top-4 emerging markets, with one of the largest telecommunications market in the world. The conference will feature not only technical and tutorial sessions, but also business application sessions and panels focused on the hottest products and services in telecommunications. Technical papers can be submitted directly at the website. Previous event had 32 technical papers and included tutorials from industry leaders, mostly from Cisco Systems. INCC 2008 is organized by the Lahore University of Management Sciences (LUMS) and offers a unique opportunity to enjoy the rich culture and Mughal heritage of Lahore.

Following are some security related codes for TinyOS:
TinyECC: Elliptic Curve Cryptography for Sensor Networks
TinyECC 1.0 is a software package providing ECC-based PKC operations that can be flexibly configured and integrated into sensor network applications. It provides a digital signature scheme (ECDSA), a key exchange protocol (ECDH), and a public key encryption scheme (ECIES). TinyECC uses a number of optimization switches, which can turn specific optimizations on or off based on developer’s needs.
TinyECC 1.0 is intended for sensor platforms running TinyOS. The current version is implemented in nesC, with additional platform-specific optimizations in inline assembly for popular sensor platforms. It has been tested on MICAz, TelosB, Tmote Sky, and Imote2. TinyECC 1.0 supports SECG recommended 128-bit, 160-bit and 192-bit elliptic curve domain parameters.
