Clustering is a key routing technique used to reduce contenergy consumption. Clustering sensors into groups, so that sensors communicate information only to cluster heads and then the cluster-heads communicate the aggregated information to the base station, saves energy and thus prolonging network lifetime. In this paper the authors propose an energy efficient cluster-heads selection algorithm through thresholding. Threshold based stable-LEACH model is extension of LEACH's algorithm. TS-LEACH concentrates on cluster-heads selection by applying the threshold.
