Autonomous underwater sensor networks

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).

The project homepage is available here.

Tmote Invent one of the top 50 products of 2006

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,”.

ACM SIGCOMM Workshop on Networked Systems for Developing Regions

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.
