MIPv6 protocol based on distance detection in LEO satellite network

Abstract

In order to address the frequent handover problem due to the satellite high-speed movement in LEO (Low Earth Orbit) satellite network, a MIPv6 (Mobile IPv6) satellite selection scheme based on distance detection is proposed to reduce the handover frequency significantly by selecting the access satellite with the maximum coverage time. Moreover, the handover latency and packet loss rate formula of MIPv6 with the different communication elevation angles and handover criterions are deduced in detail. Finally, simulations are carried out according to the settings of Iridium system. The simulation results show that the proposed satellite selection criterion can effectively reduce the handover latency and packet loss rate. This work also has some guiding significances for the setting of a communication elevation angle in satellite constellation design.
