An autonomous wireless sensor network for space applications

The importance of wireless sensor networks for space missions is shown in multiple applications, such as assembly, equipment integration, thermal and vibrations test phases in order to monitor the satellite. The high number of sensors required in space applications underscores the need for wireless sensors that save time during integration due to their simpler links and connections.     

ASTRAL, which stands for Autonomous System and TRAnsmission wireLess sensor network for space applications, is designed to develop a demonstrator to validate the concept of adapting wireless technology for space missions. The result was a demonstrator for monitoring vibration in satellites on the ground and during the launch over approximately 30 minutes.

LiteOS - OS for sensor networks

LiteOS is an open source, interactive, UNIX-like operating system designed for wireless sensor networks. With the tools that come with LiteOS, you can operate one or more wireless sensor networks in a Unix-like manner, transferring data, installing programs, retrieving results, or configuring sensors. You can also develop programs for nodes, and wirelessly distribute such programs to sensor nodes.

The LiteOS 2.0 is the latest beta version of LiteOS. It runs on the following platforms: X86/Windows XP/Vista or Linux, MicaZ or IRIS as the target mote platform, and MIB510/MIB520 as programming boards.
Funding acknowledgement: The LiteOS Project is currently supported by NSF grant CNS-0953238 (2010-2015), and was supported by NSF grant CNS-0626342, and Vodafone Fellowship (2007-2009).

Sensium ultra-low power platform for rapid development of wireless Body Area Networks (BANs)

Wearable sensor nodes (target stations) support a wide range of sensors generating data at rates up to 50kbps.
A basestation can wirelessly link up to 8 target stations, each monitoring multiple physiological signals on the body.

TZ1030 Ultra Low Power Intelligent Sensor Interface and Transceiver

Nearly all the electronics and firmware for Sensium life platform sensor nodes or basestations are integrated on to a system on chip called the

Wireless Sensing In High Alpine Environments

Warming and thawing permafrost in steep alpine bedrock can affect slope stability, lead to natural hazards and complicate the operation of man-made infrastructure. To develop theoretical models for temperature simulation and for hazard assessment, continuous and reliable data of physical parameters in natural and diverse slope areas are required

RUNES middleware

RUNES project (2007)  had a vision to enable the creation of connect next generation embedded systems composed of large numbers of heterogeneous devices. At the core of the RUNES project is a lightweight middleware framework designed to address the challenges arising in the above scenarios. This approach is based on a small and efficient middleware kernel which supports highly modularised and customisable component-based services that are run-time reconfigurable to support adaptivity.

ANT is rising

Do you know, what is ANT?
ANT provides a simple, low cost and low power solution for short range wireless communication in point-to-point and more complex network topologies. Suitable for many applications, ANT is today a proven and established technology for collection, automatic transfer and tracking of sensor data within sports, wellness management and home health monitoring applications.

Nanotron Localization module

nanoLOC AVR Module

Small Form RF Module Integrating nanoLOC TRX Transceiver and ATmel AVR Microcontroller
This smart nanoLOC AVR Module is only 35 mm by 14 mm and less than 3 mm thick. Yet, within this small form factor it integrates all the required components for a complete RF module based on Nanotron’s innovative nanoLOC TRX Transceiver. This module uses the Atmel AVR ATmega644 microcontroller and includes a band pass filter, a balun, and an integrated 2.4 GHz chip antenna.

Due to the chip’s unique chirp pulse, adjustment of the antenna is not critical. This significantly simplifies the system’s installation and maintenance (“pick and place”). A sophisticated MAC controller with CSMA/CA and TDMA support is included, as is Forward Error Correction (FEC) and 128 bit hardware encryption. To minimize software and microcontroller requirements, nanoLOC also provides scrambling, automatic address matching, and packet retransmission.

Large-Scale Demonstration of Self-Organizing Wireless Sensor Networks


On Aug. 27, 2001 researchers from the University of California,  Berkeley and the Intel Berkeley Research Lab demonstrated a self-organzing wireless sensor network consisting of over 800 tiny low-power sensor nodes.
Sensor nodes was based on TinyOS.A network discovery operation would show yellow briefly as the discovery wavefront propagated across the network and then turn off the red LED.  Because the discovery takes only a fraction of a second, we would then issue a sequence of commands to illuminate level 1, then level 2, etc. at five second intervals. Test runs in a near empty auditorium discovered a network of 800 nodes that was four levels deep.
