This book presents the latest research results in the area of secure localization for both wireless mobile ad hoc networks and wireless sensor networks. It is suitable as a text for computer science courses in wireless systems and security. It includes implementation studies with mica2 mote sensors. Due to the open spectrum nature of wireless communication, it is subject to attacks and intrusions. Hence the wireless network synchronization needs to be both robust and secure. Furthermore, issues such as energy constraints and mobility make the localization process even more challenging. The book will also interest developers of secure wireless systems.

In this book we examined the implications of design space of Time Synchronization in Wireless Sensor Network and found that existing techniques are not adequate to provide appropriately support to some important regions in the design space. We suggested a new approach to fill this gap, by extending the existing time synchronization methods and combined in new ways in order to provide services that can meet the need of applications. We suggested an algorithm to be used by each sensor node to efficiently flood the network to construct a logical hierarchical structure from a designated source point then proposed a Tree Structured Referencing Time Synchronization (TSRT) scheme to minimize the complexity of the synchronization, which works in two phases. The proposed TSRT scheme is further extended for multi-hop Time Synchronization. We described comparison study of proposed scheme with similar existing synchronization protocols. In this we presented a survey and analysis of existing clock synchronization protocols with the suggested features of TSRT for wireless sensor networks.

In this book, the authors describe the fundamental concepts and practical aspects of wireless sensor networks. The book provides a comprehensive view to this rapidly evolving field, including its many novel applications, ranging from protecting civil infrastructure to pervasive health monitoring. Using detailed examples and illustrations, this book provides an inside track on the current state of the technology. The book is divided into three parts. In Part I, several node architectures, applications and operating systems are discussed. In Part II, the basic architectural frameworks, including the key building blocks required for constructing large-scale, energy-efficient sensor networks are presented. In Part III, the challenges and approaches pertaining to local and global management strategies are presented – this includes topics on power management, sensor node localization, time synchronization, and security. At the end of each chapter, the authors provide practical exercises to help students strengthen their grip on the subject. There are more than 200 exercises altogether. Key Features: Offers a comprehensive introduction to the theoretical and practical concepts pertaining to wireless sensor networks Explains the constraints and challenges of wireless sensor network design; and discusses the most promising solutions Provides an in-depth treatment of the most critical technologies for sensor network communications, power management, security, and programming Reviews the latest research results in sensor network design, and demonstrates how the individual components fit together to build complex sensing systems for a variety of application scenarios Includes an accompanying website containing solutions to exercises (http://www.wiley.com/go/dargie_fundamentals) This book serves as an introductory text to the field of wireless sensor networks at both graduate and advanced undergraduate level, but it will also appeal to researchers and practitioners wishing to learn about sensor network technologies and their application areas, including environmental monitoring, protection of civil infrastructure, health care, precision agriculture, traffic control, and homeland security.

Adaptive techniques play a key role in modern wireless communication systems. The concept of adaptation is emphasized in the Adaptation in Wireless Communications Series through a unified framework across all layers of the wireless protocol stack ranging from the physical layer to the application layer, and from cellular systems to next-generation wireless networks. This specific volume, Adaptive Signal Processing in Wireless Communications is devoted to adaptation in the physical layer. It gives an in-depth survey of adaptive signal processing techniques used in current and future generations of wireless communication systems. Featuring the work of leading international experts, it covers adaptive channel modeling, identification and equalization, adaptive modulation and coding, adaptive multiple-input-multiple-output (MIMO) systems, and cooperative diversity. It also addresses other important aspects of adaptation in wireless communications such as hardware implementation, reconfigurable processing, and cognitive radio. A second volume in the series, Adaptation and Cross-layer Design in Wireless Networks(cat no.46039) is devoted to adaptation in the data link, network, and application layers.

This volume contains the proceedingsof EWSN 2009,the 6th European Conf- ence on Wireless Sensor Networks. The conference took place in Cork, Ireland during February11–13,2009. The aim ofthe conferencewasto discussthe latest research results and developments in the ?eld of wireless sensor networks. EWSN received a total of 145 full paper submissions of which 23 were - lectedfor publicationandpresentation,yielding anacceptancerateofjust under 16%. Paper submissions were received from 36 di?erent countries in all parts of the world. EWSN adopted a double-blind review process, where the identities of the paper authors were also withheld from the reviewers. The selection process involved well over 400 reviews with all papers being evaluated by at least three independent reviewers. In addition, the reviews were discussed by the Technical Program Committee after collecting all reviews and prior to making ?nal - cisions. The ?nal program covered a wide range of topics which were grouped into six sessions: performance and quality of service, routing, coordination and synchronization, data collection, security, evaluation and management. It - cluded theoretical and analytical approaches, together with empirical research and protocol/system design and implementation. The conference included a demo and poster session,co-chairedby Dirk Pesch andSajalDas,forwhichseparateproceedingsareavailable.
