Abstract

Mobile IPv6 permits the Mobile Node (MN) to maintain the continuous connectivity to the Internet when it moves from one access router to another. Due to both link switching delay and IPv6 protocol operation during the handover process, packets destined to the MN can be delayed or lost. This paper proposes a solution to improve the Mobile IPv6 handover performance over wireless network by introducing a new entity - Extension Handover Control Function (E-HCF). E-HCF could send the decisive control message to MN to accelerate the handover process and manage the traffic belonging to MN to reduce the packet loss. With a comparison between Mobile IPv6 and our E-HCF solution, we show that our solution allows us providing low-latency and low packet loss for real-time services during the handover.
