A Mutual Network Synchronization Method for Wireless Ad Hoc and Sensor Networks
Mutual network synchronization is a distributed method in which geographically separated clocks align their times to one another without the need of reference or master clocks. Mut...

Robust Clock Tree Routing in the Presence of Process Variations
Abstract--Advances in very large-scale integration technology make clock skew more susceptible to process variations. Notwithstanding efficient exact zero-skew algorithms, clock sk...

Combination of clock-state and clock-rate correction in fault-tolerant distributed systems
This paper proposes the integration of internal and external clock synchronization by a combination of a fault-tolerant distributed algorithm for clock state correction with a cent...

On the Feasibility of Time Estimation under Isolation Conditions in Wireless Sensor Networks
We study the problem of providing a sensor with an accurate estimate of the time, from a novel perspective which is complementary to the well-studied clock synchronization problem....

CAR: Clock with Adaptive Replacement
CLOCK is a classical cache replacement policy dating back to 1968 that was proposed as a low-complexity approximation to LRU. On every cache hit, the policy LRU needs to move the a...

Distributed Timed Automata with Independently Evolving Clocks
Abstract. We propose a model of distributed timed systems where each component is a timed automaton with a set of local clocks that evolve at a rate independent of the clocks of th...

Minimizing peak current via opposite-phase clock tree
Although a lot of research efforts have been made in the minimization of the total power consumption caused by the clock tree, no attention has been paid to the minimization of th...

An Improved Clock-skew Measurement Technique for Revealing Hidden Services
The Tor anonymisation network allows services, such as web servers, to be operated under a pseudonym. In previous work Murdoch described a novel attack to reveal such hidden servi...
