This work analyzes the performance considering real sensor nodes equipped with specific features for the access to time information at media access control (MAC) layer forocol based time synchronization in wireless sensor networks.Abstract:
Protocol based time synchronization in wireless sensor networks is a relevant issue for many researchers. In literature many papers dealing with the design and characterization of several techniques for synchronization can be found. Some of them consider only performance analysis in simulation environment, others analyze the performance considering real sensor nodes equipped with specific features for the access to time information (i.e. timestamps) at media access control (MAC) layer.read more

Analysis of quantities influencing the performance of time synchronization based on linear regression in low cost WSNs
TL;DR: A deep performance analysis is proposed aimed at highlighting the sensitivity of the regression-based algorithms to some factors that influence the accuracy in typical low cost applications, such as the finite resolution of the local timing clock and the presence of clock drift, clock high frequency noise and low frequency noise.

ELOTS: Energy-efficient local optimization time synchronization algorithm for WirelessHART networks
TL;DR: An energy-efficient local optimization time synchronization algorithm that computes the mean time offset for neighbor nodes receiving multiple reference messages, estimates the time offset by the maximum a posteriori estimation and finally adjusts the local clock according to the estimation.

Experimental analysis of the frequency diversity to improve localization in WSNs
TL;DR: The authors are aimed in exploring the influence of the most relevant causes of RSSI variability, as the multipath, and their effect on the RSSI values for WSNs by proposing a simple measurement method based on the frequency diversity able to mitigate these effects.

Some Notes on the Performance of Regression-based Time Synchronization Algorithms in Low Cost WSNs
TL;DR: A preliminary performance analysis is proposed 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, and the existence of real latencies of the radio devices.

Time Synchronization Based on CMTS: A Performance Analysis in Industry Scenarios
TL;DR: A methodological analysis to evaluate the performance of maximum consensus-based algorithm when subjected to typical disturbances due to the industrial scenarios is carried out and could then be used to build up a previsional model of achievable performance when real sensor nodes are employed and to find countermeasures able to neutralize or reduce unwanted non-idealities effects.

Fine-grained network time synchronization using reference broadcasts
TL;DR: Reference Broadcast Synchronization (RBS) as discussed by the authors is a scheme in which nodes send reference beacons to their neighbors using physical-layer broadcasts, and receivers use their arrival time as a point of reference for comparing their clocks.

The flooding time synchronization protocol
TL;DR: The FTSP achieves its robustness by utilizing periodic flooding of synchronization messages, and implicit dynamic topology update and comprehensive error compensation including clock skew estimation, which is markedly better than that of the existing RBS and TPSN algorithms.

Timing-sync protocol for sensor networks
TL;DR: It is argued that TPSN roughly gives a 2x better performance as compared to Reference Broadcast Synchronization (RBS) and verify this by implementing RBS on motes and use simulations to verify its accuracy over large-scale networks.

Clock synchronization for wireless sensor networks: a survey
TL;DR: In this paper, a survey and evaluation of clock synchronization protocols based on a palette of factors such as precision, accuracy, cost, and complexity is presented, which can help developers either in choosing an existing synchronization protocol or in defining a new protocol that is best suited to the specific needs of a sensor network application.
