Book Description
Networks naturally appear in many high-impact domains, ranging from social network analysis to disease dissemination studies to infrastructure system design. Within network studies, network connectivity plays an important role in a myriad of applications. The diversity of application areas has spurred numerous connectivity measures, each designed for some specific tasks. Depending on the complexity of connectivity measures, the computational cost of calculating the connectivity score can vary significantly. Moreover, the complexity of the connectivity would predominantly affect the hardness of connectivity optimization, which is a fundamental problem for network connectivity studies. This book presents a thorough study in network connectivity, including its concepts, computation, and optimization. Specifically, a unified connectivity measure model will be introduced to unveil the commonality among existing connectivity measures. For the connectivity computation aspect, the authors introduce the connectivity tracking problems and present several effective connectivity inference frameworks under different network settings. Taking the connectivity optimization perspective, the book analyzes the problem theoretically and introduces an approximation framework to effectively optimize the network connectivity. Lastly, the book discusses the new research frontiers and directions to explore for network connectivity studies. This book is an accessible introduction to the study of connectivity in complex networks. It is essential reading for advanced undergraduates, Ph.D. students, as well as researchers and practitioners who are interested in graph mining, data mining, and machine learning.

Book Description
This book introduces a number of recent developments on connectivity of communication networks, ranging from connectivity of large static networks and connectivity of highly dynamic networks to connectivity of small to medium sized networks. This book also introduces some applications of connectivity studies in network optimization, in network localization, and in estimating distances between nodes. The book starts with an overview of the fundamental concepts, models, tools, and methodologies used for connectivity studies. The rest of the chapters are divided into four parts: connectivity of large static networks, connectivity of highly dynamic networks, connectivity of small to medium sized networks, and applications of connectivity studies.

Book Description
Handbook of Networking & Connectivity focuses on connectivity standards in use, including hardware and software options. The book serves as a guide for solving specific problems that arise in designing and maintaining organizational networks. The selection first tackles open systems interconnection, guide to digital communications, and implementing TCP/IP in an SNA environment. Discussions focus on elimination of the SNA backbone, routing SNA over internets, connectionless versus connection-oriented networks, internet concepts, application program interfaces, basic principles of layering, protocols and services, application layer, and conformance testing. The book then takes a look at integrated services digital network, an overview of the synchronous optical network, and X.25 and worldwide networking. The publication ponders on Metropolitan Area Networks (MAN), an overview of the switched multimegabit data service, and Ethernet/802.3 and Token Ring/802.5. Topics include Ethernet versus token ring, Ethernet/802.3, customer network management, MAN conception and technology, and SMDS specifications and sources and interface protocol.

Book Description
Inhaltsangabe:Abstract: The current wave of globalisation the trend towards worldwide integration of markets is spurred by the development of ICTs, including the Internet (Miria Pigato, 2001). But there exists founded concern whether this development reaches Less Developed Countries (LDCs). Technological transformations, such as Information Communication Technology (ICT), open new possibilities in various areas. With a rapid technological development the world faces the challenge to match the pace of technological innovation with national and global policy innovation. This paper will analyse the following hypotheses: 1. Internet connectivity has potential to promote economic growth and support sustainable development for LDCs. 2. The application of the Internet technology carries risks for LDCs. 3. Successful application of Internet technology requires appropriate sustainable policies and strategies. The analysis is based upon literature review of economic and development theories, literature about ICT in development with particular focus on the Internet, country and development related information, and statistical data focussing in particular on South Africa and Uganda.

Book Description
For millennia, the Mediterranean has been one of the most active trading areas, supported by a transport network connecting riparian cities and beyond to their hinterland. The Mediterranean has complex trade patterns and routes--but with key differences from the past. It is no longer an isolated world economy: it is both a trading area and a transit area linking Europe and North Africa with the rest of the world through the hub-and-spoke structure of maritime networks. Understanding how trade connectivity works in the Mediterranean, and elsewhere, is important to policy makers, especially those in developing countries in the Mediterranean, concerned with the economic benefits of large investment in infrastructure. Better connectivity is expected to increase trade with distant markets and stimulate activities in the hinterland. This book is a practical exploration of the three interdependent dimensions of trade connectivity: maritime networks, port efficiency, and hinterland connectivity. Because of the complexity and richness of maritime and trade patterns in the Mediterranean, the research book combines both a regional focus and globally scalable lessons. This book is intended for a wide readership of policy makers in maritime affairs, trade, or industry; professionals from the world of finance or development institutions; and academics. It combines empirical analysis of microeconomic shipping and port data with three case studies of choice of port (focusing on Spain, Egypt, and Morocco) and five case studies on hinterland development (Barcelona; Malta; Marseilles; Port Said East, Egypt; and Tanger Med, Morocco).
