Wireless sensor networks: an information processing approach


Wireless sensor networks have recently come into prominence because they hold the potential to revolutionize many segments of our economy and life, from environmental monitoring and conservation, to manufacturing and business asset management, to automation in the transportation and health-care industries. The design, implementation, and operation of a sensor network requires the confluence of many disciplines, including signal processing, networking and protocols, embedded systems, information management, and distributed algorithms. Such networks are often deployed in resource-constrained environments, for instance with battery operated nodes running untethered. These constraints dictate that sensor network problems are best approached in a holistic manner, by jointly considering the physical, networking, and application layers and making major design trade-offs across the layers. Consequently, for an emerging field such as sensor networks that involves a variety of different technologies, a student or practitioner often has to be versed in several disparate research areas before he or she can start to make contributions. This book aims to provide a succinct introduction to the field of wireless sensor networks by synthesizing the diverse literature on key elements of sensor network design, such as sensor information organization, querying, and routing. The unifying theme throughout is the high-level information processing tasks that these networks are tasked to perform. It is our hope that this book will educate readers about the fundamental design principles and technology constraints of sensor networks, expose them to the many exciting and open research problems still present, and prepare them for research in this nascent area.
