Optimization of Mobile IPv6 Handover Performance Using E-HCF Method

Abstract

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.

Improving Mobile IPv6 handover and authentication in wireless network with E‐HCF

“…The link layer handover includes a discovery phase (scanning the channels to discover an available AP), an authentication phase and a reassociation phase, whereas the network layer handover is composed of a router discovery phase, a DAD phase, a binding update phase and a binding acknowledgement phase, respectively. As displayed in Figure 1, the standard MIPv6 handover latency has been estimated to a maximum value of 1290 ms [4]. This long latency is not acceptable for real-time applications such as video and audio.…”

“…HMIPv6 introduces a mobility anchor point (MAP), which acts rather like a local home agent (HA) for the visiting mobile node (MN). The concept of MAP can limit the amount of signaling required outside the MAP's domain [3,4]. FHMIPv6 [5] can reduce packet loss by providing fast IP connectivity as soon as a new link at the link layer is established.…”
