IFRC: Interference-Aware Fair Rate Control
IFRC is a distributed
congestion control scheme for wireless sensor networks.
For a wireless network consisting of N nodes sending data
to a single base station (many-to-one traffic pattern)
over multiple hops,
IFRC provides fair and
efficient rate to all the flows in the network.
IFRC has been
implemented on Tmote Sky, a wireless sensor networks
platform.

Wisden: Wireless Sensor Network
for Structural Health Monitoring
Wisden
is a wireless sensor network based data acquisition system
for structural health monitoring. Consisting of
reliable data delivery, data synchronization and data
compression schemes it provides support for data
acquisition of vibration data up to 200Hz along 3-axes.
Wisden
had been deployed on a real building (which
was shaken using hydraulic shakers) and a seismic test structure.
Experience gained from Wisden
has resulted in Tenet, a new
architecture for sensor networks. Wisden had now been
developed as an application on Tenet architecture.
