Wireless Sensor Network (WSN) technology has been in fact selected to be among the 21 most dominant technologies for the 21st century. Due to the inherent characteristics of WSN, much research is being undertaken to prolong the network lifetime and building energy efficient nodes. Clustering is one such proposed and widely exploited technique to make sensor network scalable and efficient. The chapters in this book stack up to give the reader a solid understanding of the workings of WSN and then move on to the intricacies of clustering concepts as used in WSN. This makes it a good choice for...
