Abstract:	低地球軌道衛星 (LEO) 環繞地球運行。每次軌道週期包括日光週期和陰影週期。由於衛星電池在陰影週期無法充電，較長的陰影週期會導致較大的放電深度 (DoD)，從而減少電池壽命。為了延長衛星網絡的壽命，我們提出了一種節能的路由演算法 (Baee)。我們的方法降低處於陰影週期的衛星傳輸封包的機率。為了應對突發流量和擁塞，我們平衡網絡的負載。模擬結果表明，我們的方法不僅保持低的放電深度，並實現可接受的端到端延遲。 ;Low earth orbit satellite (LEO) orbits the earth. Each orbit cycle consists of the sunlight period and eclipse period. Since satellite battery can not be charged during eclipse, long eclipse period results in deep depth of discharge (DoD), and hence reduces battery lifetime. To prolong the satellite network lifetime, we propose an energy efficient routing algorithm. Our algorithm lower the probability of the satellites in eclipse to relay packets. To handle the burst traffic and congestion, we balance network loading. Simulation result showed our method maintains not only low DoD but also acceptable end-to-end delay.
