Experimental Modeling and Measurements of Networked Wireless Sensors for Power Consumption

Power efficiency is a critical design issue in wireless sensor networks. In order to analyze the power consumption of a single node, a system model of networked wireless sensors is thus required. Based on a Petri net framework, this paper has preliminarily applied a systematic approach to the modeling and measurement of power consumption for ZigBee-equipped sensors. Moreover, several experiments have been conducted to measure the real power consumption of wireless sensor networks. It is believed that the experimental measurements presented in this paper would benefit application engineers in analyzing and understanding the power consumption of wireless sensor networks
