Research on Routing Control with Delay Constraint Based on Contact Plan for Integrated Satellite Terrestrial Network
Hao Zhang, Chunfeng Wang · 2020
Integrated satellite terrestrial network plays an increasingly important role in earth observation and space information warfare. Satellite network covers a wide range of areas and is the only means to provide Internet access and communication services in other areas. Routing research mostly focuses on the internal routing of satellite networks, without considering the integrated service requirements such as bandwidth and delay limited. This paper proposes a delay constraint routing algorithm based on contact plan(DCRM-CP). This algorithm establishes a contact plan topology map between satellite nodes, also known as contact plan list (CPL). Based on this CPL, a routing table can be established during routing search to meet the requirements of delay limitation service. Through simulation and analysis, compared with traditional routing algorithms, this algorithm improves the performance of satellite networks.
