As the structure of contemporary communication networks grows more complex, practical networked distributed systems become prone to component failures. Fault-tolerant consensus in message-passing systems allows participants in the system to agree on a common value despite the malfunction or misbehavior of some components. It is a task of fundamental importance for distributed computing, due to its numerous applications. We summarize studies on the topological conditions that determine the feasibility of consensus, mainly focusing on directed networks and the case of restricted topology knowledge at each participant. Recently, significant efforts have been devoted to fully characterize the underlying communication networks in which variations of fault-tolerant consensus can be achieved. Although the deduction of analogous topological conditions for undirected networks of known topology had shortly followed the introduction of the problem, their extension to the directed network case has been proven a highly non-trivial task. Moreover, global knowledge restrictions, inherent in modern large-scale networks, require more elaborate arguments concerning the locality of distributed computations. In this work, we present the techniques and ideas used to resolve these issues. Recent studies indicate a number of parameters that affect the topological conditions under which consensus can be achieved, namely, the fault model, the degree of system synchrony (synchronous vs. asynchronous), the type of agreement (exact vs. approximate), the level of topology knowledge, and the algorithm class used (general vs. iterative). We outline the feasibility and impossibility results for various combinations of the above parameters, extensively illustrating the relation between network topology and consensus.

This book explores the critical role of wireless consensus protocols in modern wireless networks. Building upon over two decades of research, it offers a comprehensive exploration of the fundamental principles, historical evolution, and unique challenges associated with wireless consensus. Beyond the theoretical underpinnings, the book delves into practical solutions for ensuring fault tolerance and resilience against malicious attacks, introducing cutting-edge techniques like fault-tolerant wireless consensus and Byzantine fault-tolerant wireless consensus. Recognizing the transformative potential of blockchain technology, the book also explores its integration with wireless networks, highlighting the emergence of wireless blockchain. Through in-depth analysis, real-world case studies, and forward-thinking insights, this book empowers readers to understand, design, and implement robust wireless consensus systems. Overall, wireless consensus protocols are essential for enabling reliable decision-making and coordination in wireless networks, particularly in challenging environments with unreliable communication and no central authority. These protocols empower devices to reach agreement on a common state or course of action, ensuring network consistency and security. Additionally, efficient consensus algorithms are crucial for resource-constrained wireless settings, optimizing bandwidth and energy usage to facilitate scalability and broad adoption. With applications spanning IoT, mobile computing, and distributed robotics, wireless consensus underpins critical operations like coordination and data fusion. This book serves as a valuable resource for both academics and industry professionals. Advanced-level computer science students will find it a suitable supplementary text, while researchers and practitioners seeking a deep understanding of wireless consensus protocols will benefit from its comprehensive coverage. By blending theoretical foundations with practical applications in contemporary wireless networks, this book offers a robust guide for navigating the complexities of the field.

Asynchronous On-Chip Networks and Fault-Tolerant Techniques is the first comprehensive study of fault-tolerance and fault-caused deadlock effects in asynchronous on-chip networks, aiming to overcome these drawbacks and ensure greater reliability of applications. As a promising alternative to the widely used synchronous on-chip networks for multicore processors, asynchronous on-chip networks can be vulnerable to faults even if they can deliver the same performance with much lower energy and area compared with their synchronous counterparts – faults can not only corrupt data transmission but also cause a unique type of deadlock. By adopting a new redundant code along with a dynamic fault detection and recovery scheme, the authors demonstrate that asynchronous on-chip networks can be efficiently hardened to tolerate both transient and permanent faults and overcome fault-caused deadlocks. This book will serve as an essential guide for researchers and students studying interconnection networks, fault-tolerant computing, asynchronous system design, circuit design and on-chip networking, as well as for professionals interested in designing fault-tolerant and high-throughput asynchronous circuits.

The major objective of this book is to introduce advanced design and (online) optimization methods for fault diagnosis and fault-tolerant control from different aspects. Under the aspect of system types, fault diagnosis and fault-tolerant issues are dealt with for linear time-invariant and time-varying systems as well as for nonlinear and distributed (including networked) systems. From the methodological point of view, both model-based and data-driven schemes are investigated.To allow for a self-contained study and enable an easy implementation in real applications, the necessary knowledge as well as tools in mathematics and control theory are included in this book. The main results with the fault diagnosis and fault-tolerant schemes are presented in form of algorithms and demonstrated by means of benchmark case studies. The intended audience of this book are process and control engineers, engineering students and researchers with control engineering background.
