We propose details of a novel clustering scheme which combines distributed clustering considering local node density and centralized clustering considering residual energy of sensor nodes. Our scheme dynamically adjusts to a recommended numbers of clusters and cluster size. Differing to existing clustering schemes, our scheme deploys a base station that selects proper cluster heads based on their residual energy. Our scheme greatly extends network lifetime as compare to existing schemes.
