Self-synchronization of Nonidentical Machines in Machine-to-Machine Systems

open access: yes2013 IEEE 7th International Conference on Self-Adaptive and Self-Organizing Systems, 2013
The notion of common time is very important information in distributed systems (e.g., for maintaining the consistency of distributed data). Namely, due to the lack of global time and imperfections (e.g., skew) of physical clocks, in order to agree on common time, distributed nodes have to synchronize themselves.
