Estimators for Time Synchronization—Survey, Analysis, and Outlook

Henning Puttnies, Peter Danielis, Ali Rehan Sharif, Dirk Timmermann
2020 IoT  
This survey paper differs from other surveys in particular through the consideration of wireless and wired synchronization and the focus on estimation algorithms and their achievable accuracy.  ...  In our opinion, this analysis highlights potential improvements.  ...  The author presented a comprehensive theoretical performance analysis of GraDeS. A practical implementation in TinyOS and evaluation in a testbed with 20 wireless MICAz sensor nodes are presented.  ...

2012 Journal of the Acoustical Society of America  
However, if the hard surface flooring is combined with a high performance acoustical ceiling, then the rise in noise due to the floor surface is negated with the added absorption of the improved ceiling  ...  The author also gives other acoustic analysis of the kind with pictorial presentations. THURSDAY MORNING, 17 MAY 2012 HALL A, 9:15 A.M. TO 12:40 P.M.  ...  Experiments show it's easy to implement and with high precision, good stability and efficiency. 4pUWb3.

The Virtual Bus: A Network Architecture Designed to Support Modular-Redundant Distributed Periodic Real-Time Control Systems [article]

Mark Turner, University, The Australian National
The Virtual Bus network architecture uses physical layer switching and a combination of space- and time-division multiplexing to link segments of a partial mesh network together on schedule to temporarily  ...  The Virtual Bus architecture achieves deterministic delivery times for time-sensitive traffic over multi-hop partial mesh networks by employing true line-speed switching; delays of around 15ns at each  ...  Acknowledgements Acknowledging that this is a research exercise, rather than the design and implementation of an industrial network, my goals in terms of the network size and capacity to be supported by  ...
