The groundbreaking transformations triggered by the Industry 4.0 paradigm have
dramatically reshaped the requirements for control and communication systems within the …

Emerging Cyber-Physical Systems (CPS) such as connected vehicles and smart cities span
large geographical areas. These systems are increasingly distributed and interconnected …

Precision time synchronization is critical for distributed sensing, and coordinated actuation in
various low-range wireless applications in Internet of Things and Robotics. The state-of-the …

Accurate and energy-efficient clock synchronization is an enabler for many applications of
Wireless Sensor Networks. A fine-grained synchronization is beneficial both at the system …

Clock synchronization protocols have always been tested and compared in controlled
environments. The hardware variability of different platforms, and network variability in …

Abstract Cyber Physical System (CPS) involves the integration of the Cyber World and the
Physical World. Structured Cyber-Physical Systems such as Wireless Sensor Networks …

The Beaglebone Black single-board computer is well-suited for real-time embedded
applications because its system-on-a-chip contains two" Programmable Real-time …

Geo-distributed systems ranging from databases to cyber-physical applications increasingly
rely on a shared and precise notion of time to achieve coordination. This is especially true …

Cyber-physical systems are increasingly interconnected and distributed. Examples range
from factory-scale industrial robotics to regional-scale smart grids. Therefore, to enable …

In this paper, we consider ways of using secondary “Watchdog” mechanisms to protect
primary time synchronization protocols from single-source or single-channel errors. This …
