An Enhanced Fast Handover Using Hierarchical Setup for Mobile IP

Mobile IP protocol has been designed to handle global and seamless user's mobility on the Internet. However, Mobile IP suffers from handoff latency due to slow handoff discovery and binding association notification. To reduce this latency, we propose a new handoff protocol where we attribute a high priority in using hierarchical setup with fast handoff scheme. We study the influence of various system parameters on the performance of the two handoff protocols. We present an analytical model for handoff latency for both existing and our new scheme and conduct several simulations to compare and contrast the two handoff protocols. Our analytical study and simulation results provide a significant decrease of handoff latency and there by improvises the smoothness of handoffs.
