ABSTRACT:
In this work we find a lower bound on the energy
required for synchronizing moving sensor nodes in a Wireless Sensor Network
(WSN) affected by large-scale fading, based on clock estimation techniques. The
energy required for synchronizing a WSN within a desired estimation error
level is specified by both the transmit power and the required number of
messages. In this paper we extend our previous work introducing nodes’ movement
and the average message delay in the total energy, including a comprehensive
analysis on how the distance between nodes impacts on the energy and
synchronization quality trade-off under large-scale fading effects.
