- All-IP networks become increasingly visible. The various communication networks are aimed to be connected with each other through a common IP core, so that the user will stay always online, anytime and anywhere. We believe that these networks will be the popular network in the future. However a lot of challenges remain unsolved until today. One of the major challenges is how to achieve a seamless and fast handoff while moving from one point of attachment to another.
Mobile IP Fast Authentication Protocol (MIFA) is proposed to avoid the problems of MIP and to match the real-time requirements without introducing intermediate nodes and without making any restriction on the network topology.
In this paper we evaluate the performance of MIFA compared to Mobile IP (MIP) and Handoff-Aware Wireless Access Internet Infrastructure (HAWAII). The evaluation is performed by means of network simulator 2 (ns-2). The three protocols are evaluated deploying the same topology.
Our simulation results have shown that MIFA outperforms the other two protocols with respect to handoff latency and the number of dropped packets for uplink and downlink traffic. This is because MIFA needs only to register with the new Foreign agent (FA) to be able to resume sending of packets, while MIP needs to register with the HA and HAWAII requires updating the new location at the old FA. For downlink traffic HAWAII and MIFA perform comparable to each other.
