In this work it is deduced an extended signal-to-noise (SNR) expression for embedded wireless sensor nodes. The expression can be included onto system level design methodologies for adaptive power-aware sensor acquisition design. In contrast to the conventional approach, it enables designers to estimate the achievable SNR regardless of sensor signal variations and battery voltage droop due to the depletion process. It is offered the theoretical discussion and expression usage examples.

Abstract
In this work it is deduced an extended signal-to-noise (SNR) expression for embedded wireless sensor nodes. The expression can be included onto system level design methodologies for adaptive power-aware sensor acquisition design. In contrast to the conventional approach, it enables designers to estimate the achievable SNR regardless of sensor signal variations and battery voltage droop due to the depletion process. It is offered the theoretical discussion and expression usage examples.
