       In this paper, we propose a novel, cluster-based energy balancing scheme.
       We assume the existence of a fraction of ``strong'' nodes in terms of
       abundant storage, computing and communication abilities as well as
       energy. With the transformation of the flat network infrastructure into a
       hierarchical one, we obtained significant improvements in energy
       balancing leading to a longer connected time of the network. The
       improvement is quantified by mathematical analysis and extensive
       numerical simulations.
