摘要：

This　paper　considers　maximizing　the　total　downloaded　data　from　a　CubeSats　swarm　to　ground　stations.　The　key　challenges　include　intermittent　contact　time　and　duration　with　ground　stations,　and　limited　resources.　It　aims　to　study　the　benefits　of　transferring　data　over　Inter-Satellite　Links　(ISLs).　It　presents　four　satellite-to-ground　(sog)　pairing　rules;　namely,　Pair　Transmit　Most　Data　(PTMD),　Random　Pair　(RP),　Shortest　Contact　Duration　(SCD),　and　Round　Robin　(RR).　The　results　indicate　that　ISLs　help　CubeSats　ensure　they　have　more　data　to　download　to　ground　stations.　Moreover,　the　use　of　ISLs　simplifies　sog　pairing　because　any　of　the　aforementioned　rules　can　be　used　to　yield　similar　amounts　of　downloaded　data.　©　2019　IEEE.
