Both authors have taught the course of "Distributed Systems" for many years in the respective schools. During the teaching, we feel strongly that "Distributed systems" have evolved from traditional "LAN" based distributed systems towards "Internet based" systems. Although there exist many excellent textbooks on this topic, because of the fast development of distributed systems and network programming/protocols, we have difficulty in finding an appropriate textbook for the course of "distributed systems" with orientation to the requirement of the undergraduate level study for today's distributed technology. Specifically, from - to-date concepts, algorithms, and models to implementations for both distributed system designs and application programming. Thus the philosophy behind this book is to integrate the concepts, algorithm designs and implementations of distributed systems based on network programming. After using several materials of other textbooks and research books, we found that many texts treat the distributed systems with separation of concepts, algorithm design and network programming and it is very difficult for students to map the concepts of distributed systems to the algorithm design, prototyping and implementations. This book intends to enable readers, especially postgraduates and senior undergraduate level, to study up-to-date concepts, algorithms and network programming skills for building modern distributed systems. It enables students not only to master the concepts of distributed network system but also to readily use the material introduced into implementation practices.

Small and medium-sized enterprises (SMEs) are recognized as the backbone of today's world economy. However, SMEs are well known for having limitations and acceptance barriers in adopting new technology even though the internet and communications channel's revolution has changed the way people conduct business today. Further, the COVID-19 pandemic has disturbed the operations of SMEs and increased the burden on social media application globally. It is essential that SMEs utilize social media to strengthen their performance. Strengthening SME Performance Through Social Media Adoption and Usage explores experiences in different technological, managerial, organizational, and entrepreneurial environmental issues. It focuses on different conceptions of factors and consequences influencing social media usage and SME performance. Covering topics such as corporate social responsibility, marketing frameworks, and social media adoption, this premier reference source is a valuable resource for entrepreneurs, business leaders and managers, human resource managers, marketers, consultants, students and educators of higher education, librarians, researchers, and academicians.

"The book provides an introduction to optimization theory and its applications. It is written for senior under-graduate students and first-year graduate students of telecommunication and related fields. Most applications pertain to communication and network problems. Optimization theory involves a great deal of mathematics. The book has practical examples to accompany rigorous discussion so that the reader may develop intuitive understanding on relevant concepts. The materials have been developed from course notes. By attempting to cover convex, linear, and integer optimization for a one-semester course, the author focuses on fundamental concepts and techniques rather than trying to be comprehensive. Infact, the book is written with the main intention to serve as a bridge for students with no prior background in optimization to be able to access more advanced books on the subject later on. "--

Teleservice is a common concept for distributed application services related to the use of telecommunication equipment, PCs, workstations and mainframes. Teleservices represent a diversity of applications related to various user and vendor cultures such as traditional telecommunications services, E-mail services, cooperative work, applications, multimedia applications, mobile services and intelligent network services. The complexity and diversity of teleservices are increasing, but of greater importance is the change in the way in which teleservices are designed, delivered and maintained. Information Network and Data Communications captures the cultural as well as the technical variety of teleservice.

The breathtaking success of the WDM technology in backbone networks also pushes the development and implementation of optical packet-switched WDM local and metropolitan area networks. Local and metropolitan area optical WDM networks are emerging as viable and cost-effective solutions for many telecommunication operators and service providers who have to face an extremely growing bandwidth demand and expensive additional fiber installation costs. Thus, the strong need for the development of novel high-speed architectures and protocols for such networks arises. In Optical Packet Access Protocols for WDM Networks, different basic and novel medium access control (MAC) protocols for WDM-based LANs/MANs, typically belonging to the group of single-hop networks, are proposed and analyzed. Thereby, solutions for the direct and efficient support of distinct Quality-of-Service (QoS) classes over the WDM transmission layer are provided. Besides a comprehensive overview on the state-of-the-art photonic metro networks, highly dynamic reservation-based access protocols relying on the passive-star and the ring topology are presented while assuming the deployment of wavelength-tunable transceivers at the network nodes. Optical Packet Access Protocols for WDM Networks provides both a comprehensive survey on existing WDM local and metro lightwave systems and the design of novel highly efficient medium access control protocols with QoS support for such systems. Accordingly, this work is appropriate for communication and network engineers from both the academic and industrial world working in the field of optical communication networks, computer science, and communication engineering.

This book outlines the consequences of digitization for peer-reviewed research articles published in electronic journals. It has often been argued that digitization will revolutionize scientific communication. However, this study shows that this is not the case as far as scientific journals are concerned. Authors make little or no use of the possibilities offered by the digital medium, new procedures for electronic peer review have not replaced traditional peer review, and users do not seem to accept new forms of interaction offered by some electronic journals. The main innovations are to be found at the level of the infrastructures developed by publishers. Scientists themselves appear to be reluctant to change their established patterns of behaviour in formal scientific communication.
