| Abstract | ||
| Using Software Defined Network (SDN) in space systems gains more focus nowadays. SDN can increase the reliability in satellite communication. Many researchers concluded that using SDN in satellite communication for both ground segment and space segment, improve space system reliability. The satellite ground station network has been always the backbone of the Space System. From this point of view, the reliability and performance guarantee of this network is mandatory. With the introduction of SDN in the field of satellite communications, greater capabilities have been expected to be achieved, in addition to the big reduction of operational and capital expenses in deploying and management of satellite ground network equipment. In this paper, the advantages of using SDN for handover between satellite ground stations (Site Diversity) to ensure higher reliability for the system and to increase its performance and throughput are discussed. Some scenarios have been implemented and shown in this paper to demonstrate the great potential of using SDN in ground stations handover and to help make decisions in case of link anomalies. | ||
