Download or read book Clock Synchronization with Deterministic Accuracy Guarantee written by Ryo Sugihara and published by . This book was released on 2011 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Accuracy is one of the most important performance metrics in clock synchronization. While state-of-the-art synchronization protocols achieve 1.25 sec-order average accuracy, they usually do not focus on the worst case accuracy and do not have any deterministic guarantees. This lack of accuracy guarantee makes it hard for sensor networks to be incorporated into larger systems that require more reliability than e.g., typical environmental monitoring applications do. In this paper, we present a clock synchronization algorithm with deterministic accuracy guarantee. A key observation is that the variability of oscillation frequency is much smaller in a single crystal than between different crystals. Our algorithm leverages this to achieve much tighter accuracy guarantee compared to the interval-based synchronization methods mostly proposed in the literature of distributed systems. We designed an algorithm to solve a geometric problem involving tangents to convex polygons, and implemented that in TinyOS. Experimental results show the deterministic error bound less than 9.2 clock ticks (280 1.25 sec) on average at the first hop, which is close to the simulation results. Further, by a combination with previously proposed synchronization algorithms, it achieves the estimation error of 1.54 ticks at 10 hop distance, which is more than 40% better than FTSP, while giving deterministic error bounds.

Available in PDF, EPUB and Kindle. Book excerpt: Time-Triggered Communication helps readers build an understanding of the conceptual foundation, operation, and application of time-triggered communication, which is widely used for embedded systems in a diverse range of industries. This book assembles contributions from experts that examine the differences and commonalities of the most significant protocols including: TTP, FlexRay, TTEthernet, SAFEbus, TTCAN, and LIN. Covering the spectrum, from low-cost time-triggered fieldbus networks to ultra-reliable time-triggered networks used for safety-critical applications, the authors illustrate the inherent benefits of time-triggered communication in terms of predictability, complexity management, fault-tolerance, and analytical dependability modeling, which are key aspects of safety-critical systems.

Download or read book Real time Communication Protocols for Multi hop Ad hoc Networks written by Reinhard Gotzhein and published by Springer Nature. This book was released on 2020-01-01 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on core functionalities for wireless real-time multi-hop networking with TDMA (time-division multiple access) and their integration into a flexible, versatile, fully operational, self-contained communication system. The use of wireless real-time communication technologies for the flexible networking of sensors, actuators, and controllers is a crucial building block for future production and control systems. WirelessHART and ISA 100.11a, two technologies that have been developed predominantly for industrial use, are currently available. However, a closer analysis of these approaches reveals certain deficits. Current research on wireless real-time communication systems shows potential to remove these limitations, resulting in flexible, versatile, and robust solutions that can be implemented on today’s low-cost and resource-constrained hardware platforms. Unlike other books on wireless communication, this book presents protocols located on MAC layer and above, and build on the physical (PHY) layer of standard wireless communication technologies.

Download or read book Fault Tolerant Real Time Systems written by Stefan Poledna and published by Springer Science & Business Media. This book was released on 2007-11-23 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real-time computer systems are very often subject to dependability requirements because of their application areas. Fly-by-wire airplane control systems, control of power plants, industrial process control systems and others are required to continue their function despite faults. Fault-tolerance and real-time requirements thus constitute a kind of natural combination in process control applications. Systematic fault-tolerance is based on redundancy, which is used to mask failures of individual components. The problem of replica determinism is thereby to ensure that replicated components show consistent behavior in the absence of faults. It might seem trivial that, given an identical sequence of inputs, replicated computer systems will produce consistent outputs. Unfortunately, this is not the case. The problem of replica non-determinism and the presentation of its possible solutions is the subject of Fault-Tolerant Real-Time Systems: The Problem of Replica Determinism. The field of automotive electronics is an important application area of fault-tolerant real-time systems. Systems like anti-lock braking, engine control, active suspension or vehicle dynamics control have demanding real-time and fault-tolerance requirements. These requirements have to be met even in the presence of very limited resources since cost is extremely important. Because of its interesting properties Fault-Tolerant Real-Time Systems gives an introduction to the application area of automotive electronics. The requirements of automotive electronics are a topic of discussion in the remainder of this work and are used as a benchmark to evaluate solutions to the problem of replica determinism.
