Abstract

In this paper, we analyze several issues involved in developing effective routing schemes for the LEO satellite network. It is observed that the relative movement of the satellites in the constellation has a significant impact on the ISL connectivity. Motivated by this observation, we develop a new effective algorithm called handover aware topology-slice (HATS) routing algorithm for LEO the satellite network. The algorithm focuses on reducing the delay jitter induced by changes of the ISL connectivity. It is shown that the proposed algorithm results in providing better performance in terms of the delay jitter when compared with the previously proposed routing algorithm.
