“…In [5] the authors minimize the outage probability as a function of the transmit power, which does not imply energy optimization; moreover, the authors did not consider the relative velocity of the sensing nodes in their model. The work in [6] studies the trade-off of energy consumption and synchronization accuracy from a local perspective defined by the sleep time of a node, without contemplating the energy spent in the interaction with other nodes. Energy efficiency is defined as a function of payload size in [7] for uncorrelated Rayleigh fading channels.…”

Abstract-In this paper we propose a lower bound on the energy required for synchronizing nodes in a Wireless Sensor Network (WSN) by using statistical estimation techniques. The energy required to synchronize a pair of nodes within a network with predefined synchronization accuracy is modelled as function of the transceivers power and the number of transmitted messages. In our analysis, we have considered the dynamic nature of nodes communicating within a correlated Rayleigh fading channel. A unified mathematical model has been defined to analyze the impact of nodes' relative velocity on the pairwise energy and synchronization accuracy trade-off.

“…In [11], authors propose a mechanism for synchronizing a WSN by means of constructive interference in order to achieve low duty cycles in radio operation, thus minimizing the energy spent, although they do not mention the existing trade-off between energy and synchronization accuracy. In [12], the authors expose the trade-off of energy consumption and synchronization quality from a local sleep-time perspective, without contemplating the energy spent in nodes interaction. Also, [13] aims to minimize the energy for maximum accuracy but from a local node's perspective, with low duty cycle and low frequency crystal oscillators hardware.…”

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.
