Packet Reordering Analysis for LEO Satellite Networks

In this paper we study the influences of packet reordering on the throughput and link utilization in Low Earth Orbit (LEO) satellite networks. In the absence of any packet reordering, the throughput and link utilization remain high. Our results indicate that packet reordering combined with packet error can severely deteriorate the performance of transmission in LEO satellite networks, especially at very high levels of packet reordering. Meanwhile different reordering patterns have different influences on LEO satellite networks.
