Synchronization between wireless sensor nodes is still an open question, especially in low-cost and low-power systems. In this paper we consider a type of star network in which the master periodically sends a synchronization message to the sensor nodes of its subnet. The aim of this paper is to analyze in detail the implementation limits of the commonly adopted solution, evidencing that an eccessively simple strategy leads to increasing errors or energy consumption. The solution proposed consist on implementing a continuous calibration algorithm operated by the slaves.

Abstract
Synchronization between wireless sensor nodes is still an open question, especially in low-cost and low-power systems. In this paper we consider a type of star network in which the master periodically sends a synchronization message to the sensor nodes of its subnet. The aim of this paper is to analyze in detail the implementation limits of the commonly adopted solution, evidencing that an eccessively simple strategy leads to increasing errors or energy consumption. The solution proposed consist on implementing a continuous calibration algorithm operated by the slaves.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
