For decades, a new type of terrorism has been quietly gathering ranks in the world. America's ability to remain oblivious to these new movements ended on September 11, 2001. The Islamist fanatics in the global Salafi jihad (the violent, revivalist social movement of which al Qaeda is a part) target the West, but their operations mercilessly slaughter thousands of people of all races and religions throughout the world. Marc Sageman challenges conventional wisdom about terrorism, observing that the key to mounting an effective defense against future attacks is a thorough understanding of the networks that allow these new terrorists to proliferate. Based on intensive study of biographical data on 172 participants in the jihad, Understanding Terror Networks gives us the first social explanation of the global wave of activity. Sageman traces its roots in Egypt, gestation in Afghanistan during the Soviet-Afghan war, exile in the Sudan, and growth of branches worldwide, including detailed accounts of life within the Hamburg and Montreal cells that planned attacks on the United States. U.S. government strategies to combat the jihad are based on the traditional reasons an individual was thought to turn to terrorism: poverty, trauma, madness, and ignorance. Sageman refutes all these notions, showing that, for the vast majority of the mujahedin, social bonds predated ideological commitment, and it was these social networks that inspired alienated young Muslims to join the jihad. These men, isolated from the rest of society, were transformed into fanatics yearning for martyrdom and eager to kill. The tight bonds of family and friendship, paradoxically enhanced by the tenuous links between the cell groups (making it difficult for authorities to trace connections), contributed to the jihad movement's flexibility and longevity. And although Sageman's systematic analysis highlights the crucial role the networks played in the terrorists' success, he states unequivocally that the level of commitment and choice to embrace violence were entirely their own. Understanding Terror Networks combines Sageman's scrutiny of sources, personal acquaintance with Islamic fundamentalists, deep appreciation of history, and effective application of network theory, modeling, and forensic psychology. Sageman's unique research allows him to go beyond available academic studies, which are light on facts, and journalistic narratives, which are devoid of theory. The result is a profound contribution to our understanding of the perpetrators of 9/11 that has practical implications for the war on terror.

Supplying comprehensive coverage of WSNs, this book covers the latest advances in WSN technologies. It considers some of theoretical problems in WSN, including issues with monitoring, routing, and power control, and details methodologies that can provide solutions to these problems. It examines applications of WSN across a range of fields, including health, defense military, transportation, and mining. Addressing the main challenges in applying WSNs across all phases of our life, it explains how WSNs can assist in community development.

In network design, the gap between theory and practice is woefully broad. This book narrows it, comprehensively and critically examining current network design models and methods. You will learn where mathematical modeling and algorithmic optimization have been under-utilized. At the opposite extreme, you will learn where they tend to fail to contribute to the twin goals of network efficiency and cost-savings. Most of all, you will learn precisely how to tailor theoretical models to make them as useful as possible in practice.Throughout, the authors focus on the traffic demands encountered in the real world of network design. Their generic approach, however, allows problem formulations and solutions to be applied across the board to virtually any type of backbone communication or computer network. For beginners, this book is an excellent introduction. For seasoned professionals, it provides immediate solutions and a strong foundation for further advances in the use of mathematical modeling for network design. - Written by leading researchers with a combined 40 years of industrial and academic network design experience. - Considers the development of design models for different technologies, including TCP/IP, IDN, MPLS, ATM, SONET/SDH, and WDM. - Discusses recent topics such as shortest path routing and fair bandwidth assignment in IP/MPLS networks. - Addresses proper multi-layer modeling across network layers using different technologies—for example, IP over ATM over SONET, IP over WDM, and IDN over SONET. - Covers restoration-oriented design methods that allow recovery from failures of large-capacity transport links and transit nodes. - Presents, at the end of each chapter, exercises useful to both students and practitioners.

This book constitutes the thoroughly refereed post-conference proceedings of the 5th International ICST Conference, SecureComm 2009, held in September 2009 in Athens, Greece. The 19 revised full papers and 7 revised short papers were carefully reviewed and selected from 76 submissions. The papers cover various topics such as wireless network security, network intrusion detection, security and privacy for the general internet, malware and misbehavior, sensor networks, key management, credentials and authentications, as well as secure multicast and emerging technologies.

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.
