The explosive growth of Internet-based applications and the proliferation of networking technologies have transformed not only the computer science and engineering fields but also has affected the areas of computational science and commercial Internet applications. This has provided researchers with an opportunity to explore new Internet-oriented software technologies designed to expand research and application opportunities in multimedia, commerce, and the scientific and high-performance computing applications community. Two emerging technologies - agents and active networks - provide increased programmability to bring new services to Internet-based applications. The chapters in this volume are based on presentations at the Second Annual Workshop on Active Middleware Services. The volume draws on research results in active networks, mobile and intelligent agents, software tools for high-performance distributed computing, network operating systems, and application programming models and environments.The text should be appropriate for engineers and researchers in the areas of network centric computing and distributed information systems, as well as for application and tool developers and users of information systems.

Wireless Sensor Networks presents a comprehensive and tightly organized compilation of chapters that surveys many of the exciting research developments taking place in this field. Chapters are written by several of the leading researchers exclusively for this book. Authors address many of the key challenges faced in the design, analysis and deployment of wireless sensor networks. Included is coverage of low-cost sensor devices equipped with wireless interfaces, sensor network protocols for large scale sensor networks, data storage and compression techniques, security architectures and mechanisms, and many practical applications that relate to use in environmental, military, medical, industrial and home networks. The book is organized into six parts starting with basic concepts and energy efficient hardware design principles. The second part addresses networking protocols for sensor networks and describes medium access control, routing and transport protocols. In addition to networking, data management is an important challenge given the high volumes of data that are generated by sensor nodes.Part III is on data storage and manipulation in sensor networks, and part IV deals with security protocols and mechanisms for wireless sensor networks. Sensor network localization systems and network management techniques are covered in Part V. The final part focuses on target detection and habitat monitoring applications of sensor networks. This book is intended for researchers starting work in the field and for practitioners seeking a comprehensive overview of the various aspects of building a sensor network. It is also an invaluable reference resource for all wireless network professionals.

The papers in this volume were presented at the Second Annual Work­ shop on Active Middleware Services and were selected for inclusion here by the Editors. The AMS workshop was organized with support from both the National Science Foundation and the CAT center at the Uni­ versity of Arizona, and was held in Pittsburgh, Pennsylvania, on August 1, 2000, in conjunction with the 9th IEEE International Symposium on High Performance Distributed Computing (HPDC-9). The explosive growth of Internet-based applications and the prolifer­ ation of networking technologies has been transforming most areas of computer science and engineering as well as computational science and commercial application areas. This opens an outstanding opportunity to explore new, Internet-oriented software technologies that will open new research and application opportunities not only for the multimedia and commercial world, but also for the scientific and high-performance computing applications community. Two emerging technologies - agents and active networks - allow increased programmability to enable bring­ ing new services to Internet based applications. The AMS workshop presented research results and working papers in the areas of active net­ works, mobile and intelligent agents, software tools for high performance distributed computing, network operating systems, and application pro­ gramming models and environments. The success of an endeavor such as this depends on the contributions of many individuals. We would like to thank Dr. Frederica Darema and the NSF for sponsoring the workshop.
