快速响应激光卫星通信网络的鲁棒动态拓扑控制
Robust dynamic topology control for ORS satellite laser communication networks
摘要
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 pro-cesses. Due to their high computational complexity and large delay,the existing free space networks(FSO)topol-ogy 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 pro-cess,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-orga-nized and near real-time,it which meets the requirements of dynamic topology control well and will contribute to building operationally responsive space(ORS)satellite networks.关键词
