From the WSN Security website editors:
The main idea behind the WSN Security website is to keep a list of any work related to Wireless Sensor Networks (WSNs) security that has been published
in journals, conference proceedings, technical reports, theses, book chapters, and eprints. The list maybe incomplete since we are still in the process of updating it. The website contains conferences CFPs where WSN Security is one of the conferences’ scope.
The website will be updated on an irregular basis depending on the feedback of the papers’ authors and the flow of papers published in the domain.
The website address is: www.wsn-security.info
According to CSIRO, the FLECK sensors could be the platform for the next generation of water quality monitoring systems, providing real-time data collection with unprecedented detail and speed. The FLECK sensor nodes operate in a meshed network, setting up ad hoc networks to wireless transfer environmental data they have collected.
Using the technology, SEQWater and CSIRO will be able to monitor high rainfall, droughts and contaminants in real-time. An autonomous solar-powered catamaran is also part of the solution, and it can be instructed by the network to carry out more detailed sampling as needed.
Seventy of the 120 nodes are land-based and spread across the catchment area, while 45 are floating and measure water temperature. The sensor system is manually controlled through a PDA, web interface, or web-enabled mobile phones.
Far from being just an accessory, mobile phones are starting to be used to collect data in an increasing number of disciplines.
When Martin Lukac felt a small earthquake rattle his Los Angeles apartment, he immediately thought of the mobile phone lying on his desk. Two weeks earlier, he had programmed the phone to capture readings from its built-in accelerometer, a sensor originally intended to support features such as games. Now, Lukac — a doctoral student in computer science at the University of California, Los Angeles — transferred the phone’s data to his computer and saw the readings plotted as a series of tell-tale spikes. Success! His phone had become a mobile seismometer.

The 2009 International Workshop on Pervasive Multimedia Sensor Networks (PMSN’09) will be held in conjunction with the 7th IEEE/IFIP International Conference on Embedded and Ubiquitous Computing (EUC-09), August 29th-31st, 2009, Vancouver, Canada.
Given the development of low-cost imaging sensors, CMOS cameras, sensitive microphones, PMSN have been proposed and drawn lots of attention from the research community. PMSN are a new and emerging type of sensor networks that have the potential to enable a large class of applications: assisting elderly in public spaces, multimedia surveillance networks, target tracking, environmental monitoring, and traffic management systems.

ACme is an open source hardware and software platform that enables wireless energy/power measurement and control of AC devices. The ACme node fills the gap between inexpensive LCD watt-meters (e.g. Kill-A-Watt) and expensive networked enterprise energy monitors. The ACme network is an IPv6 based mesh network that enables direct IP communication with individual ACme nodes.
