Abstract
This paper presents the modeling of a sensor mote energy consumption together with the battery state-of-charge for wireless sensors network (WSN) using SystemC and the analog/mixed signal (AMS) extension. This model is intended to be employed in the simulation of WSN composed from few to several nodes. The energy consumption of the whole mote device has been described as a finite state machine with SystemC, which was characterized from a measured mote. The battery was modeled in SystemC-AMS and was implemented for an alkaline AA battery to describe its state-of-charge and the nonlinear behaviour of the voltage source. For illustration, a WSN composed of ZigBee motes, which is actually employed for the monitoring of dissolved oxygen, pH and temperature in water for shrimp farming, is presented.
