Power management issues in energy harvesting wireless sensor networks
May 12, 2010 // Pierre Mars
Wireless sensor networks (WSNs) are becoming ubiquitous as they can solve problems in many applications. In building control, WSNs use light energy or RF energy to power motion detectors which turn off lights if nobody is detected in a room, to dim lights depending on the light level in a room, and to sense and report temperature for air conditioning or heating. In industrial control, WSNs use vibration energy or thermal energy to monitor and report the condition of rotating machines. In location tracking, they use vibration energy to enable GPS to sense and the cellular network to report the position of containers, trucks or rail cars.
