Abstract
Providing high-speed Internet service using satellite network has attracted researchers from both academia and industry mainly due to the characteristics of Low Earth Orbit (LEO) satellite networks such as global coverage, scalability, and lower transmission delay. With the recent advancements in the Software-Defined Network (SDN), implementation of SDN in Non-Terrestrial Networks (NTN) can help to achieve the set goals for 5G and beyond networks. Since satellite networks have a distinct architecture, some of the traditional protocols no longer remain useful. Therefore, to satisfy the diverse Quality of Service (QoS) requirements for a variety of applications, we propose a novel and centralized QoS-aware routing algorithm, called fybrrLink in which the global view of the network in SDN is utilized. We implement a modified Bresenham's algorithm and Dijkstra's algorithm to find the…
