Some Novel Applications for Wireless Inertial Sensors
Sensors have followed a corollary of Moore’s Law as they progressively decrease in size, cost, and often power. Nowhere is this more evident than with inertial sensor systems, as MEMS-based devices become steadily smaller and [...]
Experimental Localization with MICA2 Motes
As research into Wireless Sensor Networks (WSNs) increases, it becomes more and more apparent that knowledge of sensors’ physical position within a network is a necessity. A sensor’s data are only useful if put in [...]
Size does matter – the case for big motes
An account is given of the two scools of mote design for wireless sensor networks, the maxi-mote and the mini-mote. Both approaches have their advantages, but it is argued that the maxi-mote approach is more [...]
