隨著網絡流量需求的上升，具有較低延遲特性的LEO衛星網絡的研究越來越受到關注。衛星軌道的周期可分為兩個：日光週期和日蝕週期。在日蝕週期期間，衛星僅由電池供電。過度使用電池會導致放電深度變深，造成電池壽命變短。在本論文中，我們提出了一種負載均衡最短路徑路由法。每顆衛星根據能量狀態、衛星間鏈路的不穩定性、擁塞程度和路由長度選擇下一跳。並且基於歷史流量分佈，仿真結果表明我們的方法可以成功地延長衛星電池的壽命，降低擁塞程度和最大鍊路利用率。;With the rise of network traffic demand, low-latency LEO satellite networks have become more popular. The period of the satellite orbit can be divided into two: the sunlight period and the eclipse period. In the eclipse period, the satellite is only powered by its battery. Overusing a battery will lead to a high depth of discharge and a short lifetime of the battery. In this thesis, we proposed a load balance shortest-path routing algorithm. Each satellite chooses the next hop according to energy status, instability of inter-satellite link, congestion level, and route length. And based on the historic traffic distribution, the simulation results showed our method can successfully prolong the lifetime of the satellite battery, reduce the congestion level and the maximal link utilization.
