|Abstract:Inter-satellite laser communication has the advantages of high data rate, long transmission distance and low probability of detection/intercept. It has become an important trend in satellite networking technology. The inter-satellite point-to-point laser links have high movability, and narrow beam width, which bring challenges to the PAT processes. Due to high computational complexity and large network delay, the existing FSO topology control strategies cannot be directly applied to the inter-satellite laser communication networks. In this article, an algebraic connectivity based network dynamic topology control scheme is proposed. With distributed network construction and network 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 satellite laser communication network dynamic topology control well, and will contribute to building ORS satellite networks.
