(. Its core is an energy-efficient non-uniform clustering algorithm for organizing network topology, in which candidate cluster heads construct clusters of different sizes by using non-uniform competition scheme. The scheme of the cluster close to the agglomeration point is smaller than that of the cluster farther from the agglomeration point, so the cluster head close to the agglomeration point can reserve energy for data forwarding between clusters. Simulation results show that the routing protocol effectively balances the energy consumption of cluster heads and extends significantly)
