Wireless sensor networks consist of small, autonomous devices with wireless networking capabilities. In order to further increase the applicability in real world applications, minimizing energy consumption is one of the most critical issues. Therefore, accurate energy model is required for the evaluation of wireless sensor networks. In this paper, the energy consumption for Wireless Sensor Network (WSN) node is analyzed. To estimate the lifetime of sensor node, the energy characteristics of sensor node are measured.
