Abstract
In this article, the routing in massive low earth orbit (LEO) satellite
networks is studied. When the satellite-to-satellite communication
distance is limited, we choose different relay satellites to minimize
the latency in a constellation at a constant altitude. First, the global
optimum solution is obtained in the ideal scenario when there are
available satellites at all the ideal locations. Next, we propose a nearest
neighbor search algorithm for realistic (nonideal) scenarios with a
limited number of satellites. The proposed algorithm can approach
the global optimum solution under an ideal scenario through a finite
number of iterations and a tiny range of searches. Compared with
other routing strategies, the proposed algorithm shows significant
advantages in terms of latency. Furthermore, we provide two approximation techniques that can give tight lower and upper bounds for the
latency of the proposed algorithm, respectively. Finally, the relationships between latency and constellation height, satellites’ number, and
communication distance are investigated.
