TLDR
A probabilistic method is proposed for reading remote clocks in distributed systems subject to unbounded random communication delays and can achieve clock synchronization precisions superior to those attainable by previously published clock synchronization algorithms.Abstract:
A probabilistic method is proposed for reading remote clocks in distributed systems subject to unbounded random communication delays. The method can achieve clock synchronization precisions superior to those attainable by previously published clock synchronization algorithms. Its use is illustrated by presenting a time service which maintains externally (and hence, internally) synchronized clocks in the presence of process, communication and clock failures.read more

Optimistische Replikation in mobilen ad-hoc Netzen
TL;DR: An optimistic replication approach for mobile ad-hoc networks is presented and it is demonstrated that it is suitable for use in small to medium-sized MANET scenarios with up to 40 participants and a small number of transaction aborts.

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.

Optimal clock synchronization
T. K. Srikanth,Sam Toueg +1 more
TL;DR: This is the first known solution that achieves optimal accuracy—the accuracy of synchronized clocks (with respect to real time) is as good as that specified for the underlying hardware clocks.

A new fault-tolerant algorithm for clock synchronization
Jennifer Lundelius,Nancy Lynch +1 more
TL;DR: A new fault-tolerant algorithm for solving a variant of Lamport's clock synchronization problem for a system of distributed processes that communicate by sending messages, which solves the problem of maintaining closely synchronized local times, assuming that processes' local times are closely synchronized initially.

A new fault-tolerant algorithm for clock synchronization
Jennifer L. Welch,Nancy Lynch +1 more
TL;DR: A new fault-tolerant algorithm for solving a variant of Lamport's clock synchronization problem for a system of distributed processes that communicate by sending messages that maintains synchronization to within a small constant, whose magnitude depends upon the rate of clock drift, the message delivery time and its uncertainty.
