Wireless Sensor Networks (WSNs) consist of hundreds to thousands of battery-powered tiny sensors that are endowed with a multitude of sensing modalities including multi-media (e.g., video, audio) and scalar data (e.g., temperature, pressure, light, infrared). The high demand for WSNs has been spurred by numerous applications that require in-situ, unattended, high-precision, and real-time observation over the monitored region. Although there have been significant progress in sensor fabrications including processing design and computing, advances of battery technology still lag behind, making energy resource the fundamental constraint in WSNs.
