Abstract
AbstractTime synchronization in low-cost wireless sensor networks based on synchronization algorithm is a today relevant issue as for the networks costs, energy consumption and indoor uses aspects. Among the other those based on the one way messaging and, in particular, on the adoption of regressive algorithms are widely used in many application contexts. This paper proposes a preliminary performance analysis aimed at highlighting the sensitivity of the regression-based algorithms versus some influence factor typical of the low cost applications, such as the finite resolution of the timing clock, the presence of clock drift, clock jitter and wander, the presence of real latencies of the radio devices, the presence of real latencies of the microcontroller device. The aim is to weight the influence of each one of these influence factors on the overall synchronization performance. The analysis is carried out a suitable and controlled experimental environment.KeywordsMicrocontroller DeviceReal LatticeClock DriftClock JitterChannel Medium Access (MAC)These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
