The sensors used for monitoring and capturing data related to the physical conditions of the environment are known as wireless sensors. These sensors are spatially dispersed to monitor environmental and physical conditions like pollution, sound and temperature. A major use of wireless sensor networks is found in environmental and earth sensing which includes forest fire detection, water quality monitoring, air pollution monitoring, natural disaster prevention, etc. Some other areas of application include health care monitoring and industrial monitoring. This book strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within the field of wireless sensor networks. The topics included in it are of utmost significance and bound to provide incredible insights to readers. Students, researchers, experts and all associated with wireless sensor networks will benefit alike from the book.
