This paper describes the modeling of a microsensor node dedicated to wireless sensor network applications. The definition of the different node modes is first introduced: wake-up, measure, processing, transmission, reception and sleep. Then, contrary to the literature, a complete sensor node energy model is derived and used to analyze node autonomy. This model allows to estimate the part of each element...
Wireless sensor node (WSN) lifetime is correlated with the battery current usage profile. State of the art in wireless sensor nodes current consumption shows that available models have not been extensively tested and experimentally validated. This work aims to seek answers to the following questions: is it accurate the node lifetime prediction obtained with available models? Moreover, is the radio...
