Wireless Sensor Networks (WSNs) consist of small, autonomous nodes (motes) which combine sensing, computing and wireless transmitting capabilities. Deployed in an application scenario, the motes can take sensor measurements, process the gathered data, and subsequently send the results to other motes or external devices using the on-board radio transmitter. Many existing node platforms, such as Crossbow's TelosB or MICAz motes, are based on microcontrollers operating at low system clock frequencies due to the tight energy constraints of battery-powered operation. Combined with their limited memory resources, performing computationally intensive algorithms is almost impossible.
