Abstract:Inter-satellite laser links have the advantages of high data rate, long transmission distance and low probability of detection/intercept. It has become an important trend in satellite technology. The inter-satellite point-to-point laser links are high mobility, and have narrow beam width, which bring challenges to the PAT processes. Due to their high computational complexity and large delay, the existing FSO topology control strategies cannot be directly applied to satellite networks. In this article, an algebraic connectivity based network dynamic topology control scheme is proposed. With distributed construction and enhancement process, the network dynamic reconfiguration is accomplished. A modified edge perturbation method is developed, and proved to have lower computational complexity than existing methods. The scheme is distributed, self-organized and near real-time, it meets the requirements of dynamic topology control well and will contribute to building ORS satellite networks.
