Performance analysis of the mobile IP fast authentication protocol

ABSTRACT

Latency during handoffs affects the service quality of real-time applications. This paper describes the Mobile IP Fast Authentication protocol (MIFA) and introduces a simple analytical performance model to evaluate this protocol compared to Mobile IP (MIP) and Hierarchical Mobile IP (HMIP). Our performance study shows that the handoff latency of MIFA is independent of the distance between the current Foreign Agent (current FA) and the Home Agent (HA). Thus, MIFA highly reduces the handoff latency for most cases. MIFA clearly outperforms MIP with respect to the handoff latency and the number of packets dropped due to handoffs. In addition, MIFA performs similar to HMIP when the MN moves within a domain consisting of two hierarchy levels only and outperforms HMIP otherwise. Different from HMIP, MIFA does not require additional network elements as HMIP does. Thus, MIFA conforms to the standard MIP approach and the IP philosophy to confine host-specific processing to the end systems as much as possible.
