A dynamic routing mechanism based on Drosophila optimization algorithm is proposed to improve the energy efficiency of data center network.Firstly, the data center network energy efficiency model is deduced. Then, the energy-saving routing mechanism based on Drosophila optimization algorithm is designed, Simulating the foraging process of flies, we constantly adjust and optimize the direction and location of the foraging strategy, and propose to decide the heuristic of the next node, and finally obtain the best energy-saving route. On this basis, we propose an energy-efficient routing algorithm based on fruit fly optimization Finally, the effectiveness of the algorithm is verified through simulation experiments. Experiments show that the proposed algorithm is superior to the existing algorithms in improving energy efficiency.
