This volume is a collection of 16 articles contributed by influential experts in the field of Steiner tree applications. The articles are designed to explore the impact on industries of the long-term theoretical development of Steiner tree problems. The authors address various Steiner tree problems originating from and applied to industry fields, such as the design of electronic circuits, telecommunication networks, computer networks, and computer biology. This book should be a good reference tool for scientists who depend on Steiner tree problems in some way.

This comprehensive volume offers a collection of 28 state-of-the-art articles contributed by experts of pattern recognition, string matching, or both. It contains fundamental concepts and notations, as well as reports on contemporary research with respect to both methodology and applications. In particular, it includes string matching related techniques for structural pattern recognition. It also explores many applications of pattern recognition strategies to image segmentation, intrusion detection, handwriting recognition and others.

Wireless networking enables two or more computers to communicate using standard network protocols without network cables. Since their emergence in the 1970s, wireless networks have become increasingly pop­ ular in the computing industry. In the past decade, wireless networks have enabled true mobility. There are currently two versions of mobile wireless networks. An infrastructure network contains a wired backbone with the last hop being wireless. The cellular phone system is an exam­ ple of an infrastructure network. A multihop ad hoc wireless network has no infrastructure and is thus entirely wireless. A wireless sensor network is an example of a multihop ad hoc wireless network. Ad hoc wireless networking is a technique to support robust and ef­ ficient operation in mobile wireless networks by incorporating routing functionality into mobile hosts. This technique will be used to realize the dream of "anywhere and anytime computing", which is termed mo­ bile computing. Mobile computing is a new paradigm of computing in which users carrying portable devices have access to shared infrastruc­ ture in any location at any time. Mobile computing is a very challenging topic for scientists in computer science and electrical engineering. The representative system for ad hoc wireless networking is called MANET, an acronym for "Mobile Ad hoc NETworks". MANET is an autonomous system consisting of mobile hosts connected by wireless links which can be quickly deployed.

The research and development of pattern recognition have proven to be of importance in science, technology, and human activity. Many useful concepts and tools from different disciplines have been employed in pattern recognition. Among them is string matching, which receives much theoretical and practical attention. String matching is also an important topic in combinatorial optimization. This book is devoted to recent advances in pattern recognition and string matching. It consists of twenty eight chapters written by different authors, addressing a broad range of topics such as those from classifica­ tion, matching, mining, feature selection, and applications. Each chapter is self-contained, and presents either novel methodological approaches or applications of existing theories and techniques. The aim, intent, and motivation for publishing this book is to pro­ vide a reference tool for the increasing number of readers who depend upon pattern recognition or string matching in some way. This includes students and professionals in computer science, mathematics, statistics, and electrical engineering. We wish to thank all the authors for their valuable efforts, which made this book a reality. Thanks also go to all reviewers who gave generously of their time and expertise.

This book explores the critical role of wireless consensus protocols in modern wireless networks.

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.
