The Handoff Study on Satellite Networks Based on Mobility Network
In order to provide the Internet access for the users in large mobile networks and achieve the IP routing in the satellite constellation network, a new design method based on mobile network is put forward for LEO satellite constellation networks which realizes the IP route selection function and reduces the dependence of satellite constellation communication network to the ground network. Then, a fast VMR-based handoff and authentication method is presented to realize the seamless connection between the user segment networks and correspondence nodes. At last, we test the validity of the proposed satellite constellation network architecture and compare the VMR-based handoff method with the basic handoff in MIPv6 through the NS2 simulation. The simulation results indicate that the proposed network architecture can meet the future satellite constellation development demand, and the time delay in the proposed handoff method is lower than the basic method in MIPv6.
