Wireless Sensor Networks and Applications

Wireless sensor networks are being employed in a variety applications ra- ing from medical to military, and from home to industry. The principle aim of this book is to provide a reference tool for the increasing number of scientists who depend upon sensor networks in some way. The book is organized into several sections, each including chapters exploring a speci?c topic. Wireless sensor networks are attracting great attention and there are many research topics yet to be studied. In this book, the topics covered include n- work design and modelling, network management, data management, security and applications. The articles presented in the book are expository, but of a scholarly nature, including the appropriate history background, a review of the state-of-the-art thinking relative to the topic, as well as a discussion of unsolved problems that are of special interest. The target readers of this book include the researchers in computer s- ence, computer engineering, and applied mathematics, as well as students in these subjects. Specialists as well as general readers will ?nd the articles st- ulating and helpful. Book Organization The book is organized into ?ve sections. Section I introduces the design and modelling of sensor networks. Chapter 1, by Iyer, Kulkarni, Mhatre, and Rosenberg, presents a taxonomy of wireless sensor networks, based on their application level objectives, tra–c characteristics and data delivery requi- ments. Popa and Lewis in Chapter 2 describe some algorithms for systematic exploration of unknown environments using a mobile wireless sensor network.

Wireless sensor networks are currently being employed in a variety of applications ranging from medical to military, and from home to industry. Wireless Sensor Networks and Applications aims to provide a reference tool for the increasing number of scientists who depend upon reliable sensor networks.

The book is divided into five sections: design and modeling, network management, data management, security, and applications. The eighteen self-contained chapters are authored by experts in wireless networking. Each chapter is given expository but also scholarly treatment, covering the history of its specific topic, reviewing state-of-the-art thinking relative to the topic, and discussing currently unsolved problems of special interest.

Key Features:

*Explores different access control protocols and wake up strategies in wireless sensor networks;

*Discusses several time-synchronization techniques and challenges, i.e., directed diffusion, tiny aggression, greedy aggression on directed diffusion;

*Provides insights in network security, i.e., secure routing, and proper management;

*Elaborates on numerous wireless sensor network applications, i.e., the ExScal application and the XSM platform.

The topics covered within this book are intended for researchers, computer engineers, applied mathematicians, and graduate students interested in wireless sensor networks, but uninformed readers may also find this volume stimulating and helpful.
