By using multi-hop communication mode

wireless sensor networks（WSNs） routing protocol

to a certain extent

solves the problem of premature disability of cluster head nodes at single-hop mode

enhances the stability of network communication

and improves energy efficiency of the network.However

by the multi-hop mode

cluster head nodes close to base station work on a lot of data forwarding

leading to their premature death

network empty

shortening the life cycle.Aiming at this problem

proposes optimized clustering routing strategy based on quantum evolutionary algorithm（QEA）

through diversities of QEA

rapid convergence

global search ability

and so on

so as to optimizes inter-cluster routing

further more balances effectively the energy consumption among cluster head nodes.Simulation results show that compared with classic LEACH and EEUC protocol

optimized clustering routing strategy based on QEA can balance the cluster head node energy consumption and prolong the network lifetime effectively.
