Case studies, based on direct experience of the authors applying wireless sensor networks, describe the design methodology and the type of measurement used, along with a sample of performance measurement is achieved. This book will enable you to answer important questions such as: * How long does my network still alive given the amount of sensing required it? * For how long do I have to set the sleep state of my motes? * How many sensors should I distribute to meet the expected requirements of the application? * What kind of throughput can I expect as a function of the number of nodes deployed and the radio interface chosen (whether it be Bluetooth or Zigbee)? * How is the Packet Error Rate of my Zigbee motes affected by the selection of adjacent frequency sub-band at 2.4GHz ISM band? * How precise localization depends on the number of nodes deployed in the hallway? Communications and signal processing engineers, researchers and graduate students working in wireless sensor networks will find this book an invaluable practical guide to this important technology. "This book provides the right balance between theory and application, which is the book for their R & D engineers who want to appreciate the why, how and where the domain Wireless Sensor Networks can be best applied." - Fabio Bellifemine, Telecom Italia "This book is a thorough explanation and can be accessed on a wireless sensor network with a good balance between theory and practice, but valuable for students and practicing engineers, and is an important addition to technical libraries." - Professor Moe Win, Associate Professor at the Laboratory for Information and Decision Systems (LIDS), Massachusetts Institute of Technology * The book is only to test the wireless network sensor technology and assess their performance capabilities against possible applications * Allows the engineer to select the technology that will give the best performance for the intended application * Case studies, based on direct experience of the authors of applying wireless sensor networks, describe the design methodology and the type of measurement used, along with a sample of performance measurement is achieved.
