This book which covers various insights on the Wireless sensor networks its working topology and nature with the aspects of clustering in concentric.Nowadays wireless sensor networks plays a crucial role in sensing and transmitting some important data that to be processed and crucial decisions were made for some specific applications.Clustering is one of the important technique which helps for various research domains like image processing, machine learning and network processing.Clustering approach is followed for the aggregation of nodes and group them into various groups, so that sensor nodes could be filtered and monitored easily. All the four chapters deals with the focus on increasing the lifetime of the sensor node of a wireless sensor network and various clustering methodology followed with some clustering algorithm is been described effectively with more number of references.This book is been organized in a way that pose the reader to ask themselves about Why? What ? How? Clustering technique is used to aggregation of the sensor nodes and data transmission between the clusters to the base station, as the base station is the location for processing data, reaching base station in short time.As a final note the researchers could use this book as a major research note for performing the research process of Wireless sensor networks with respect to lifetime of the sensor node using clustering technique.
