| Abstract: | An enhanced correspondent agent is introduced to collaborate with the home agent and the foreign agent to support a route optimization approach in mobile IP over WLAN: bi-directional direct tunnel,which supports subnet-based optimization and binding optimization.The proposed approach can improve the routing efficiency for mobile IP and reduce the handoff latency for mobile nodes.In addition,the paper also analyses the influences brought by ingress-filtering routers and gives the corresponding solution. |
