This paper examines six provably correct fault-tolerant clock synchronization algorithms and argues for the use of such algorithms in life-critical applications.Abstract:
This paper examines six provably correct fault-tolerant clock synchronization algorithms. These algorithms are all presented in the same notation to enable easier comprehension and comparison. The advantages and disadvantages of the different techniques are examined and issues related to the implementation of these algorithms are discussed. The paper argues for the use of such algorithms in life-critical applications.read more

Self-adaptive clock synchronization for computational grid
TL;DR: In this paper, an asynchronous self-adaptive clock synchronization mechanism is proposed to synchronize physical clocks for a computational grid, in particular for the computational grid linked through the asynchronous Intranet or Internet environments.

Self-adaptive clock synchronization for computational grid
TL;DR: A node self-adaptive model is presented, and the relationship between the clock precision and synchronization time is induced, hence a node can predict when it should begin the synchronization process.

Synchronizing clocks in the presence of faults
TL;DR: Three algorithms for maintaining clock synchrony in a distributed multiprocess system where each process has its own clock work in the presence of arbitrary clock or process failures, including “two-faced clocks” that present different values to different processes.

Fault-tolerant clock synchronization
TL;DR: Two simple efficient distributed algorithms are given: one for keeping clocks in a network synchronized and one for allowing new processors to join the network with their clocks synchronized.
