Information processing in sensor networks is a rapidly emerging area of computer science and electrical engineering research. Because of advances in micro-sensors, wireless networking and embedded processing, ad hoc networks of sensor are becoming increasingly available for commercial, military, and homeland security applications. Examples include monitoring (e.g., traffic, habitat, security), industrail sensing and diagnostics (e.g., factory, appliances), infrastructures (i.e., power grid, water distribution, waste disposal) and battle awareness (e.g., multi-target tracking). This book introduces practitioners to the fundamental issues and technology constraints concerning various aspects of sensor networks such as information organization, querying, routing, and self-organization using concrete examples and does so by using concrete examples from current research and implementation efforts.

Key Features

·Written for practitioners, researchers, and students and relevant to all application areas, including environmental monitoring, industrial sensing and diagnostics, automotive and transportation, security and surveillance, military and battlefield uses, and large-scale infrastructural maintenance. ·Skillfully integrates the many disciplines at work in wireless sensor network design: signal processing and estimation, communication theory and protocols, distributed algorithms and databases, probabilistic reasoning, energy-aware computing, design methodologies, evaluation metrics, and more. ·Demonstrates how querying, data routing, and network self-organization can support high-level information-processing tasks.


Sensor networking and embedded systems professionals including development engineers, research scientists, system architects, etc., in a wide variety of companies from the defense industry to the home computing and electronics industry.

Wireless sensor and actuator nets, also known as motes and smart dust, are an emerging computer class based on a new platform, networking structure, and interface that enable novel, low cost, high volume, applications. This text and reference is a critical link to create this new class by covering the field of study for both practitioners and researchers. Unlike earlier computer classes that have been mostly evolutionary, motes require the “tall, thin man” that Carver Mead used to describe custom VLSI design. Motes system research and development require, deep knowledge of radio links, networks, operating systems, each application, and their interaction. Zhao and Guibas provide an excellent foundation for embarking on understanding and building these new systems. --Gordon Bell, Senior Researcher, Microsoft Corporation This book provides both an insightful overview of the emerging field of wireless sensor networks, and an in depth treatment of algorithmic signal and information processing issues. An excellent text for both professionals and students! --Deborah Estrin, Center for Embedded Networked Sensing, UCLA
