Design on the Simulation Platform for Mobility Management in LEO Satellite Network Based on OPNET
Mobility management is one of the key technologies in low earth orbit(LEO) satellite network. In this paper, an OPNET based simulation platform of mobility management for LEO satellite network is proposed to take advantage of OPNET in the simulation of satellite network. The performance simulation of mobility management on the platform is actualized. The location update rates of different schemes and different handoff rates are gained. This simulation platform provides a foundation for improving the performance of mobility management for LEO satellite constellation system.
