Wireless Sensor Networks

This comprehensive book introduces readers step-by-step to all aspects of wireless sensor networks (WSNs). Each chapter is followed by a list of references, making reading consistent and continuous. Exercises and practical setups are included as necessary. The first chapters lay out the book structure and introduce WSNs and their applications before discussing the necessary middleware. Chapter IV addresses the energy concerns and illustrates the available energy models and the concept of energy harvesting, while Chapter V deals with the tricky area of the management of security, defining threats and attacks and how to prevent them. Cryptography and key management are also addressed, with a focus on secure routing and secure location and secure data aggregation. The following two chapters show how placement should be performed to achieve acceptable coverage and present routing algorithms from a WSN's perspective, typically, secure routing, geographic routing, energy aware routing and quality-of service (QoS)-based routing. Chapter VIII offers insights into WSN protocols. QoS is a must for networks, Chapter IX reveals QoS metrics for WSNs as compared to other networks. The final chapters discuss research topics and several simulation tools used in studying and analyzing WSN environments. The book is rounded out by two appendices listing the must-know WSN manufacturers and datasheets. This book is intended for a wide readership, encompassing senior students, as well as those in industry.
