Analysis of power loss in sensor node (Unode)

Abstract

Wireless sensor networks are important, and have potential in many innovations in the future. One of the most important factors is to increase the lifetime of the battery power as long as possible. It is an easy method to increase the supply voltage to meet the requirements of sensor nodes (Unode) by connecting them in series. However, our study shows that the excessive supply voltage can produce power loss in the device more than in necessary. In the experimental results, the lifetime of battery has been deducted by 13-60%. Moreover, it also causes the increase in the difference of power consumption between normal operating mode and transmitting mode at 11-26%.
