Contents I. Introduction
With the rapid development of the fifth generation of mobile and satellite communication technology, satellite networks have become an essential part of the global communication system. Low-orbit satellite networks can provide global coverage. The LEO satellite network can provide communication services between remote areas inaccessible to terrestrial networks, and the LEO satellite network can alleviate the communication pressure on terrestrial networks to a certain extent. [1], [2]. However, in the real LEO satellite networking scenarios, due to the situation's complexity in outer space, hardware damage, electromagnetic interference, military sabotage, distance changes, limited energy carrying, etc., are likely to lead to satellite node damage or failure. All of which will significantly impact the communication of the satellite network. Low-Earth-orbit satellites generally run in space orbit, the cost of its repair is very high, and the repair is time-consuming. As the actual environment of satellite operation is too harsh, there are various kinds of satellite failures, which makes it more challenging to overcome the satellite failures caused by the satellite working environment.
