Abstract
Home Agent (HA) is an indispensable entity for binding connectivity to route packets between Mobile Node (MN) and Correspondent Node (CN). MIPv6 allows the deployment of redundant HAs to overcome HA failure. Different approaches resolve this issue to recuperate binding association information. This paper compares the effect of handoff latency in various methods and proposes a Reliable HA delivery (RHAD) mechanism to mitigate the Binding Update (BU) registration latency in HA at the time of active HA failure. We use BGP domain in network architecture and apply IBGP protocol to transmit packets between Edge Router (ER) and HA. Both the theoretical evaluation and simulation results reveal that RHAD effectively reduces BU re-registration handoff latency and increases packet delivery ratio.
