Abstract
In optical satellite network, the possible optical inter-satellite links (OISLs) candidate for each satellite are usually more than laser communication terminals (LCTs) equipped. This poses the link assignment problem (LAP) of how to assign LCTs of each satellite to establish OISLs with the others. In order to make full use of huge bandwidth provided by LCT, the problem of assigning all satellite LCTs to establish OISLs is modeled as a perfect matching problem in the perfect match model, where a perfect matching is searched over a mixed complete bipartite graph. The regular, random greedy and perfect match model based link assignment schemes are considered. Simulation results show that the average node-to-node distance and LCT utilization of perfect match model based link assignment scheme are better than the regular and random greedy link assignment schemes.
