HSWA-TCP: A New Traffc Control Algorithm for High-speed Satellite Communication Networks

High speed satellite communication networks are emerging as a part of the future global wirelesscommunication systems. However, existing transmissioncontrol protocols for satellite communication networks donot provide satisfactory performance over high speed satellite links due to their ineffcient congestion avoidance algorithms. This paper identifies the reason for low throughputof a widely used protocol - Space communications protocol specification (SCPS) - in such networks, and proposes anew congestion avoidance algorithm to overcome the drawback of the congestion avoidance algorithm used in SCPS.Simulation results show that, compared with its legacycounterpart, the proposed new algorithm can achieve significant improvement in throughput performance with avariety of link BER ranges in high speed satellite communication networks.
