The time slot assignment problem in clusters of SS/TDMA satellite systems interconnected through intersatellite links is studied. The authors show that the problem of finding an assignment which minimizes the total transmission time is NP-complete, i. e. , computationally intractable, even for quite restricted intersatellite link patterns and simplified system models. Successively, they focus attention on clusters of two satellites, proposing a branch-and-bound optimal algorithm and two fast heuristic algorithms. They investigate the performance of the proposed heuristic algorithms both by a theoretical worst case bound and by simulation trials showing that the produced solutions are close to the optimal on the average.

Abstract

The time slot assignment problem in clusters of SS/TDMA satellite systems interconnected through intersatellite links is studied. The authors show that the problem of finding an assignment which minimizes the total transmission time is NP-complete, i. e. , computationally intractable, even for quite restricted intersatellite link patterns and simplified system models. Successively, they focus attention on clusters of two satellites, proposing a branch-and-bound optimal algorithm and two fast heuristic algorithms. They investigate the performance of the proposed heuristic algorithms both by a theoretical worst case bound and by simulation trials showing that the produced solutions are close to the optimal on the average.
