Aiming at cluster header selection and transmission problem of wireless sensor networks（ WSNs）

a new type network routing protocol CRP-FOAGA is proposed based on greedy algorithm and the improved fruit fly optimization algorithm. In this protocol

the fitness function is presented by the node location and remaining energy

the optimal solution of the fitness function is solved with the improved fruit fly optimization algorithm

and multi hop transmission of cluster head node is realized using the greedy algorithm. Simulation results show that the algorithm makes a reasonable planing of the distribution of cluster head node

reduce energy consumption of the network

improve lifetime of the network

and has better performance.
