Real-time systems rely on a distributed global time base. As any physical clock device suffers from noise, it is necessary to provide some kind of clock synchronization to establish such a global time base. Different clock synchronization methods have been invented for individual application domains. The Precision Time Protocol (PTP), which is specified in IEEE 1588, is another interesting option. It targets local networks, where it is acceptable to assume small amounts of hardware support, and…

A Simulation Model of IEEE 802.1AS gPTP for Clock Synchronization in OMNeT++
TLDR
A new simulation model of the gPTP protocol for time synchronization in OMNeT++ using the INET library is developed, compared it to results from the state-of-the-art, and would like to share it with the OM NeT++ community.

TLDR
An extension of Precision Time Protocol to enable energy-efficient clock synchronization between the nodes within Wireless Sensor Network (WSN) to reduce clock convergence time and energy needed by considering out-degree of clocks without sacrificing synchronization accuracy is proposed.
Simulation and Analysis of Time Synchronization System for Seafloor Observatory Network Using OMNeT++
TLDR
The basic architecture of the time synchronization system for the seafloor observatory network is introduced and deployment suggestions are proved to be rational and effective according to the performance of the asymmetric delay of the PTP clock port in simulation and evaluation.
An Extension to the Precision Time Protocol (PTP) to Enable the Detection of Cyber Attacks
TLDR
This article proposes to close the PTP loop through an extension that introduces new functionality and messages and demonstrates that the approach preserves PTP functionality, while successfully detecting cyber attacks against PTP components in a timely manner.
Detection and Mitigation of Cyber Attacks on Time Synchronization Protocols for the Smart Grid
TLDR
This thesis focuses on the substation, a basic block of the smart grid system, along with its recommended time synchronization mechanism - the Precision Time Protocol (PTP) - in order to address threats associated with PTP, and proposes practical and efficient detection, prevention, mitigation techniques and methodologies that will harden and enhance the security and usability of PTP in a substation.

Simulation of Time-synchronized Networks using IEEE 1588-2008
TLDR
The goal of this thesis was to develop a simulation framework for PTP, which helps system designers carrying out Design Space Exploration (DSE) and to reach this goal, this thesis presents two software projects: LibPLN: a portable, efficient software library to generate realistic oscillator noise and LibPTP: a simulationframework for P TP devices.
IEEE 1588 standard for a precision clock synchronization protocol for networked measurement and control systems
TLDR
This paper discusses the major features and design objectives of the IEEE-1588 standard, designed to serve the clock synchronization needs of industrial systems, and recent performance results of prototype implementations of this standard in an Ethernet environment are presented.
Measurement, Control, and Communication Using IEEE 1588
A common sense of time among the elements of a distributed measurement and control system allows the use of new techniques in solving problems with complex synchronization requirements or arising
Achieving a Realistic Notion of Time in Discrete Event Simulation
TLDR
The results show that the behaviour of distributed sensor systems, resulting from imperfect timebases, can be accurately simulated, and a model that was optimised for use in DES is presented.
DISCRETE SIMULATION OF POWER LAW NOISE
TLDR
A new algorithm and computer code is presented for simulating power law noises with arbitrary a and it is shown to provide improvements, particularly because it results in non-stationary noise sequences that are also scale- invariant and causal and have the proper autospectral densities and Allan variances.
