Abstract

With the development of satellite communication, in order to solve the problems of shortage of on-board resources and refinement of delay requirements to improve the communication performance of satellite optical networks, this paper proposes a bee colony optimization algorithm for routing and wavelength assignment based on directional guidance (D-BCO-RWA) in satellite optical networks. In D-BCO-RWA, directional guidance based on relative position and link load is defined, and then the link cost function in the path search stage is established based on the directional guidance factor. Finally, feasible solutions are expanded in the global optimization stage. The wavelength utilization, communication success probability, blocking rate, communication hops and convergence characteristic are simulated. The results show that the performance of the proposed algorithm is improved compared with existing algorithms.
