Abstract
Wireless sensor networks are obtaining a great relevancy in civil as military applications. These
networks consist of a distributed set of sensor nodes which have very high restrictions for battery
replacement and power consumption. Therefore, in order to give some recommendations to de-
velopers and optimize the energy spent of these devices, it is very signicant to know how much
power each component or basic operation consumes.
In this paper we analyze the power consumption for wireless sensor networks. Our study focus
in two basic operations: CPU state change and data transfer and receive.
Our results show CPU state changing to low-power mode has a cost which must be taken into
account to decide performing the transition. Also, we show an accurate measurement evaluation
of the data transfer.
