Resumen:
In this work we find a lower bound on the energy required for
synchronizing a Wireless Sensor Network (WSN) based on clock estimation
techniques. The energy required for synchronizing a WSN is specified
by both the transmit power and the number of transmitted messages in
order to achieve a desired estimation error level. This paper brings
two main contributions: 1. A general relationship between the energy
spent in the transmission and the clock offset estimation error by
means of the number of transmitted messages, for both large-scale and
small-scale wireless channel fading. 2. An optimal lower bound value on
the required energy and the number of messages by minimizing their
product.
