Communications: Wireless in Developing Countries and Networks of the Future The present book contains the proceedings of two conferences held at the World Computer Congress 2010 in Brisbane, Australia (September 20–23) organized by the International Federation for Information Processing (IFIP): the Third IFIP TC 6 Int- national Conference on Wireless Communications and Information Technology for Developing Countries (WCITD 2010) and the IFIP TC 6 International Network of the Future Conference (NF 2010). The main objective of these two IFIP conferences on communications is to provide a platform for the exchange of recent and original c- tributions in wireless networks in developing countries and networks of the future. There are many exiting trends and developments in the communications industry, several of which are related to advances in wireless networks, and next-generation Internet. It is commonly believed in the communications industry that a new gene- tion should appear in the next ten years. Yet there are a number of issues that are being worked on in various industry research and development labs and universities towards enabling wireless high-speed networks, virtualization techniques, smart n- works, high-level security schemes, etc. We would like to thank the members of the Program Committees and the external reviewers and we hope these proceedings will be very useful to all researchers int- ested in the fields of wireless networks and future network technologies.

This book brings together conceptual and empirical insights to explore the interconnections between social networks based on Information and Communication Technologies (ICT) and travel behaviour in urban environments. Over the past decade, rapid development of ICT has led to extensive social impacts and influence on travel and mobility patterns within urban spaces. A new field of research of digital social networks and travel behaviour is now emerging. This book presents state-of-the-art knowledge, cutting-edge research and integrated analysis methods from the fields of social networks, travel behaviour and urban analysis. It explores the challenges related to the question of how we can synchronize among social networks activities, transport means, intelligent communication/information technologies and the urban form. This innovative book encourages multidisciplinary insights and fusion among three disciplines of social networks, travel behaviour and urban analysis. It offers new horizons for research and will be of interest to students and scholars studying mobilities, transport studies, urban geography, urban planning, the built environment and urban policy.

This collective volume explores the ways merchants managed to connect different spaces all over the globe in the early modern period by organizing the movement of goods, capital, information and cultural objects between different commercial maritime systems in the Mediterranean and Atlantic basin. Merchants and Trade Networks in the Atlantic and the Mediterranean, 1550-1800 consists of four thematic blocs: theoretical considerations, the social composition of networks, connected spaces, networks between formal and informal exchange, as well as possible failures of ties. This edited volume features eleven contributions who deal with theoretical concepts such as social network analysis, globalization, social capital and trust. In addition, several chapters analyze the coexistence of mono-cultural and transnational networks, deal with network failure and shifting network geographies, and assess the impact of kinship for building up international networks between the Mediterranean and the Atlantic. This work evaluates the use of specific network types for building up connections across the Mediterranean and the Atlantic Basin stretching out to Central Europe, the Northern Sea and the Pacific. This book is of interest to those who study history of economics and maritime economics, as well as historians and scholars from other disciplines working on maritime shipping, port studies, migration, foreign mercantile communities, trade policies and mercantilism.

This book is an introduction to maximum-entropy models of random graphs with given topological properties and their applications. Its original contribution is the reformulation of many seemingly different problems in the study of both real networks and graph theory within the unified framework of maximum entropy. Particular emphasis is put on the detection of structural patterns in real networks, on the reconstruction of the properties of networks from partial information, and on the enumeration and sampling of graphs with given properties. After a first introductory chapter explaining the motivation, focus, aim and message of the book, chapter 2 introduces the formal construction of maximum-entropy ensembles of graphs with local topological constraints. Chapter 3 focuses on the problem of pattern detection in real networks and provides a powerful way to disentangle nontrivial higher-order structural features from those that can be traced back to simpler local constraints. Chapter 4 focuses on the problem of network reconstruction and introduces various advanced techniques to reliably infer the topology of a network from partial local information. Chapter 5 is devoted to the reformulation of certain “hard” combinatorial operations, such as the enumeration and unbiased sampling of graphs with given constraints, within a “softened” maximum-entropy framework. A final chapter offers various overarching remarks and take-home messages.By requiring no prior knowledge of network theory, the book targets a broad audience ranging from PhD students approaching these topics for the first time to senior researchers interested in the application of advanced network techniques to their field.

This book provides an overview of the latest research and development of new technologies for cognitive radio, mobile communications, and wireless networks. The contributors discuss the research and requirement analysis and initial standardization work towards 5G cellular systems and the capacity problems it presents. They show how cognitive radio, with the capability to flexibly adapt its parameters, has been proposed as the enabling technology for unlicensed secondary users to dynamically access the licensed spectrum owned by legacy primary users on a negotiated or an opportunistic basis. They go on to show how cognitive radio is now perceived in a much broader paradigm that will contribute to solve the resource allocation problem that 5G requirements raise. The chapters represent hand-selected expanded papers from EAI sponsored and hosted conferences such as the 12th EAI International Conference on Mobile and Ubiquitous Systems, the 11th EAI International Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness, the 10th International Conference on Cognitive Radio Oriented Wireless Networks, the 8th International Conference on Mobile Multimedia Communications, and the EAI International Conference on Software Defined Wireless Networks and Cognitive Technologies for IoT.

Annotation. The most common complaints of today's cell phone users are poor reception, a lost signal that cuts off a call, and the inability to put a call through. Today's wireless providers struggle to ensure these problems do not occur. This book is an in-depth examination of two of the hottest research areas relating to these challenges: location management and mobile wireless routing.
