To solve the problem appearing in distributed clustering routing multi-hop communication,this paper proposes an energy balanced forwarding algorithm(EBFA) based on distributed clustering routing proto-cols. EBFA adopts the uneven clustering techniques and multi-hop inter-cluster strategy. During the multi-hop for-warding,the social welfare function is introduced to pre-assess the extent of energy balance between nodes in the da-ta forwarding path,and the node with a better energy balance is chosen as the forwarding node. Simulation resultsshow that:Compared to LEACH and EEUC,EBFA prolongs the lifetime of the network and balances the energy con-sumption among sensor nodes,which solves the hot zone problem in the multi-hop routing.
