This book investigates the intersection of terrorism, digital technologies and cyberspace. The evolving field of cyber-terrorism research is dominated by single-perspective, technological, political, or sociological texts. In contrast, Terrorism Online uses a multi-disciplinary framework to provide a broader introduction to debates and developments that have largely been conducted in isolation. Drawing together key academics from a range of disciplinary fields, including Computer Science, Engineering, Social Psychology, International Relations, Law and Politics, the volume focuses on three broad themes: 1) how – and why – do terrorists engage with the Internet, digital technologies and cyberspace?; 2) what threat do these various activities pose, and to whom?; 3) how might these activities be prevented, deterred or addressed? Exploring these themes, the book engages with a range of contemporary case studies and different forms of terrorism: from lone-actor terrorists and protest activities associated with ‘hacktivist’ groups to state-based terrorism. Through the book’s engagement with questions of law, politics, technology and beyond, the volume offers a holistic approach to cyberterrorism which provides a unique and invaluable contribution to this subject matter. This book will be of great interest to students of cybersecurity, security studies, terrorism and International Relations.

Multimedia service provisioning is believed to be one of the prerequisites to guarantee the success of next-generation wireless networks. Examining the role of multimedia in state-of-the-art wireless systems and networks, Broadband Mobile Multimedia: Techniques and Applications presents a collection of introductory concepts, fundamental techniques, the latest advances, and open issues in this important area.Divided into four sections, the volume begins with an introduction to various broadband wireless multimedia systems. Using video as an application example, it then focuses on the routing and cross-layer design issue of multimedia communication over multihop wireless ad hoc and sensor networks. The next section discusses issues related to multimedia communications over WLANs—a dominant part of today’s broadband wireless access networks. The book concludes with recent developments in quality-of-service (QoS) provisioning mechanisms and other enabling technologies, including middleware, mobility management, scheduling, and power control. With numerous illustrative figures and extensive references, this useful technical guide gives in-depth treatments of basic topics, a solid overview of cutting-edge advances, and a representative sampling of important research outcomes.

Cyberterrorism

This is the first book to present a multidisciplinary approach to cyberterrorism. It traces the threat posed by cyberterrorism today, with chapters discussing possible technological vulnerabilities, potential motivations to engage in cyberterrorism, and the challenges of distinguishing this from other cyber threats. The book also addresses the range of potential responses to this threat by exploring policy and legislative frameworks as well as a diversity of techniques for deterring or countering terrorism in cyber environments. The case studies throughout the book are global in scope and include the United States, United Kingdom, Australia, New Zealand and Canada.With contributions from distinguished experts with backgrounds including international relations, law, engineering, computer science, public policy and politics, Cyberterrorism: Understanding, Assessment and Response offers a cutting edge analysis of contemporary debate on, and issues surrounding, cyberterrorism. This global scope and diversity of perspectives ensure it is of great interest to academics, students, practitioners, policymakers and other stakeholders with an interest in cyber security.

This book covers the design, construction, and implementation of algebraic-geometric codes from Hermitian curves. Matlab simulations of algebraic-geometric codes and Reed-Solomon codes compare their bit error rate using different modulation schemes over additive white Gaussian noise channel model. Simulation results of Algebraic-geometric codes bit error rate performance using quadrature amplitude modulation (16QAM and 64QAM) are presented for the first time and shown to outperform Reed-Solomon codes at various code rates and channel models. The book proposes algebraic-geometric block turbo codes. It also presents simulation results that show an improved bit error rate performance at the cost of high system complexity due to using algebraic-geometric codes and Chase-Pyndiah’s algorithm simultaneously. The book proposes algebraic-geometric irregular block turbo codes (AG-IBTC) to reduce system complexity. Simulation results for AG-IBTCs are presented for the first time.
