Access Control Algorithm of Data Relay Satellite with Microwave and Laser Hybrid Links based on Jobs Type
According to oversubscribed requests problem of user satellite for data relay access, the types of job and the features of the multi-constraint of access control are studied. A constraint satisfaction model is established based on it. The link access flexibility and jobs′ conflict set are set according to the jobs type, valid time and priority setting. To maximize the number of priority weighted jobs, an access control algorithm of data relay satellite with microwave and laser hybrid links is introduced. The double-layer optimization hybrid links algorithm is based on the jobs type and adaptive small-window ant colony algorithm. The sequence of jobs access and the selection of relay satellite link are set as optimization objects. Simulation results show that the model can realize multi-type jobs access control efficiently. The proposed double-layer optimization algorithm is better than the single-layer optimization, and it is with a faster convergence speed and better global optimization ability. So the proposed algorithm can effectively solve the multi-type jobs with multiconstraint, multi-antenna and multiple relay satellites access control problem.
