Routing and Spectrum Allocation for Multi-Layer Satellite Ad Hoc Networks
Jinxi Qian, Chendi Feng, Mai Yang and Qingyuan Liu

With the popularization of broadband services and the rapid development of the Internet, the demand for bandwidth is growing explosively, and ad hoc network with no center, self-organization and dynamic topology has become the future development trend. As a complex and large-scale ad hoc network, the multi-layer satellite network has higher requirements for the robustness of the network and the ability to manage distributed resources. In addition, routing and spectrum allocation problem is the key to realize large capacity and highly efficient data transmission in multi-layer satellite network, therefore an adaptive routing and spectrum allocation scheme based on business needs is proposed. Combined with the dual constraint conditions of spectrum continuity and spectrum adjacency, it realizes the optimal route and resource allocation for different business under light and heavy load. Simulation results show the effectiveness of the proposed scheme and the application of different methods.

Keywords: multi-layer satellite networks, routing, spectrum allocation, ant colony algorithm, network architecture
