Routing and Wavelength Assignment Algorithm for LEO Satellite Based on Path Weight
Routing and wavelength assignment algorithms for Low Earth Orbit (LEO) satellite communication are studied in this paper. Based on intersatellite hops and wavelength utilization, the calculation model of path weight is established. In order to achieve the optimal allocation of routing and wavelength resources in Software Defined Network (SDN) network architecture, path selection and wavelength allocation are completed from the perspective of path weight. Finally, the proposed algorithm is compared with the existing algorithms. The simulation results show that the proposed algorithm can reduce the blocking rate and improve the wavelength utilization.
