A Networking Transmission Method in the Case of Limited Satellite Transceiver

Abstract

AbstractDue to the cost and hardware limitations of the satellite, it is difficult for a single satellite to establish multiple data communication links at the same time. When the satellite network carries a large amount of data transmission, efficient network transmission in this resource-constrained network has become a challenge. Considering the constraints of a single transceiver, we propose a topology planning method based on connectivity fairness, and formulate the rules for satellite transceiver rotation; on this basis, we design a low-delay routing method under resource constraints, which is characterized by time-varying graphs, and uses traffic to calculate single or multiple paths that meet transmision requirements, which not only ensures equal connectivity opportunities, but also reduces the delay of end-to-end paths. Finally, relying on the iridium constellation, under the connectivity fairness topology configuration method, we simulate and analyze the algorithm, and prove that the network transmission has a lower path delay than the satellite over-the-top transmission.KeywordsResource constraintsConnectivity fairnessLow-delay routingNetworking transmission
