Wireless sensor networks are usually deployed in a way “once deployed, never changed”. The actions of sensor nodes are either pre-scheduled inside chips or triggered to respon...
Abstract—Energy is the most precious resource in wireless sensor networks. To ensure sustainable operations, wireless sensor systems need to harvest energy from environments. The...

— We present a dynamic optimization approach to save energy in Wireless Sensor Networks (WSN) at the link level. One of the main sources of energy waste in a WSN is idle listenin...
Accurate and scalable simulation has historically been a key enabling factor for systems research. We present TOSSIM, a simulator for TinyOS wireless sensor networks. By exploitin...
