Abstract

With the increasing number of satellites, the problem of satellite networking becomes more and more important. However, due to the limited link resources of satellite nodes, it is difficult to comprehensively consider the limited number of satellite node connections in the existing network. In this paper, we define the degree of satellite as the number of link connections for satellite nodes. In the softwaredefined satellite network, we put forward the node model and link model under degree constraints. Besides, we propose a heuristic algorithm for satellite network topology generation based on link weight based on the software-defined satellite network under the constraint of degree. Simulation results show that the heuristic algorithm has better average link bandwidth, average link rate and average link delay than the traditional degree-constrained shortest path algorithm.
