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, the paper proposes a new handoff protocol where it attributes a high priority to registration request datagrams. As a result, each router prioritizes this datagram whenever received, which reduces the round-trip delay of the registration request. Using a queuing model, the paper presents an analytical model for handoff latency for both mobile IP protocol and the new scheme. Then, it conducts several simulations to compare and contrast the two handoff protocols.
