The Sensors lab at University of Massachusetts, Amherst has made a public release of Capsule, which is a rich object-based storage system for sensors that supports flexible use of available flash memory by sensor applications.

52°North is an open initiative that advances the development of cutting edge open source geospatial software. The initial focii of the open source technology development are Sensor Web Enablement (SWE) , Web Security and Digital Rights Management (DRM) . Other streams of work will open up according to community direction.
They host a collection of Java based web services implementations. Their products are published solely under the GNU General Public License (GPL) , but are also available – via a dual licensing model – to commercial users.
As an example, the 52N Sensor Observation Service enables interoperable, web-based access to sensors and real-time geosensor data. This product implements the current OGC Sensor Observation Service draft specification to access sensor information (SensorML) and sensor observations (O&M).
The 52N SOS allows specificatzion-conform provision of georeferenced measurement data. As a result, it is easily integrated in geodata-infrastructures and geoservice-infrastructures. In situ sensors (e.g. water gages), as well as remote sensing sensors can be used for data collection.

Advances in sensor technology and distributed computing, coupled with the development of open standards that facilitate sensor/sensor network interoperability, are contributing to the emergence of a phenomenon known as the ‘Sensor Web’. This phenomenon can be described as an advanced Spatial Data Infrastructure (SDI) in which different sensors and sensor networks are combined to create a sensor-rich feedback control paradigm.
Featuring an advanced and scalable architecture that supports numerous diverse and heterogeneous sensor types, a Sensor Web includes a range of sensors such as flood gauges, air pollution monitors, stress gauges on bridges, Webcams and satellite-borne Earth imaging devices.
A number of organisations are doing their own sensor web research. A collaborative research platform called the Sensor Web Alliance (SWA) has been founded. The aim is to pool resources in the SWA, coordinate research and allow participating organisations to share IP, which will spread risk and lower the cost of entry.

I came along an interesting project aimed at developing fully autonomous underwater sensor networks to protect critical infrastructure and water resources. The name of the project is DISCOVERY, which stands for Distributed Intelligence, Sensing and Coordination in Variable Environments.
DISCOVERY uses CSIRO-developed sensors called FLECK modules, which consist of a low-power processor, flash memory, radio transceiver, and rechargeable battery, and autonomous submersible robots with propulsion, actuation, acoustic and optical communication capabilities.
Ultimately these networks will be used to identify hazards to structures such as off-shore oil rigs. In order to operate in an underwater environment, the basic FLECK units will be equipped with compound-specific chemical sensing and potentially in-situ power harvesting. The DISCOVERY project is also carrying out a physics-based simulation of the distributed multi-agent networks it aims to create using the modified FLECK units cooperating with autonomous underwater vehicles (AUVs).

In their November issue, Sensors Magazine named Moteiv’s Tmote Invent system one of the top 50 products of 2006. The complete article is available here, and about Tmote Invent you can read:
“The Tmote Invent wireless sensor system from Moteiv Corp., San Francisco, CA, lets you build and install custom wireless sensor applications more easily and cheaply. Software uses the company’s distribution of TinyOS. (415-692-0960, http://www.moteiv.com/)”.
The ACM SIGCOMM Workshop on Networked Systems for Developing Regions (NSDR) will be held with ACM SIGCOMM 2007 at Koyoto, Japan, 27-31 August, 2007 (exact date to be decided).
The purpose of NSDR 2007 is to provide a venue for researchers to propose and discuss ideas and to participate in the sustainable development and deployment of Internet and communication technologies specifically aimed at developing third world countries.
Areas of interest include, but are not limited to:
– Delay Tolerant Networking: delay-tolerant Internet access in developing regions, DTN routing over wireless rural links, etc.
– Rural Wireless: long-distance 802.11, WiMaX solutions, directional antennas, etc.
– Low-cost Computing Devices: low-cost end-user devices which constitute the network, mobile phones as primary computing devices, task-specific devices, etc.
– Sensor Networks: sensor-nets designed specifically for developing regions
– Power-Efficient Systems: power-efficient computing architectures, power-efficient network infrastructure, power-efficient mobile systems, etc.
– Sustainable Deployment: pricing models for sustainable deployment of communication infrastructure etc.
– Applications: healthcare, disaster management, education etc.
