Energy Efficient Clustering and Localization in Wireless Sensor Networks

Energy of the sensor nodes is valuable and scarce in Wireless sensor Networks (WSNs) therefore it is vital to reduce energy consumption in order to improve lifetime of WSN. An excellent way to do so is to divide sensor network into groups of cluster and sink node, where cluster head acts as leader of the cluster. For WSNs with a large number of such sensors, it is very important to use a method which automatically arranges the sensors in clusters such that minimum energy is used to communicate information from all nodes to the respective base station.
