MPTCP Performance Simulation in Multiple LEO Satellite Environment

Interest in satellite communication with multiple Low Earth Orbit (LEO) satellites have been growing recently. This technology offers a higher bandwidth and improved reliability since users can connect to multiple satellites simultaneously. In this environment, satellites are in constant motion; links may be added or dropped dynamically, which could have an adverse effect on TCP. Multipath TCP (MPTCP) is ideal for this environment. To confirm the utility of MPTCP in a multiple LEO satellite environment, we studied the performance of MPTCP with various configurations using Mininet simulation. We simulated the connectivity of three satellites and measured the throughput while dynamically adding or dropping the links. The results show that MPTCP performs well by utilizing all available links at any moment.
