Unbalanced energy consumption is an inherent problem in gradient sinking sensor networks. This uneven energy dissipation can lead to the existence of energy holes, and significantly reduce network lifetime. In this paper, our study is based on corona-based network division. We investigate the unbalanced energy consumption among nodes both within the same coronas and within different coronas. We take advantage of mixed-routing strategy to achieve balanced energy consumption among nodes both within the same coronas and within different coronas. Besides, once the mixed-routing strategy can not balance energy consumption in local areas, the strategy of nonuniform energy distribution is used in these areas. Finally, we give algorithms to compute the optimal data distribution ratio and the initial energy of nodes. Simulation results show that our strategy can reduce the energy consumption, avoid energy holes and prolong the network lifetime dramatically.
