A network-based handover scheme in HIP-based mobile networks

In the Host Identity Protocol (HIP), the existing host-based handover scheme tends to induce large handover delaysand packet loss rates. To deal with this problem, we are proposinga network-based handover scheme for HIP in the mobile networks, in which the access routers of the mobile node will establish a handover tunnel andwillperform the route optimization for data transmission. We also discuss how to extend the HIP Update message to use the proposed handover scheme. From ns-2 simulations, we can seethat the proposed handover scheme can significantly reduce the handover delay and packet losses during handover, as compared to the existing handover schemes.
