ABSTRACT
Energy continues to be the key constraint in wireless sensor networks. We review existing methods for estimating software power consumption and battery modelling, as applied to embedded systems such as Wireless Sensor Networks. We consider current developments in hardware and software technology, in particular the availability of high-fidelity simulators. Once such simulator, TOSSIM for TinyOS 1.x, models power consumption via a plugin, PowerTOSSIM. We complete the port of PowerTOSSIM to TinyOS 2.0 for the latest model of sensor node, the MICAz. Finally, we extend the simulator to model non-linear battery effects.
