Abstract
Significant problems in basic mobile IPv6
occur due to its inability to support micro-mobility
because of long delay and high packet loss during
handover. Hierarchical mobile IPv6 (HMIPv6) as an
extension of basic Mobile IPv6 solves the problem by
separating the handover management to macromobility
and micro-mobility. HMIPv6 introduced a
new protocol element called Mobility Anchor Point
(MAP) to manage the mobility. HMIPv6 can reduce
the delay and the amount of signaling during
handover. However the protocol still cannot meet the
requirement for traffic that is delay sensitive such as
voice especially in macro mobility management.
Duplicate address detection and the transmission time
for the handover operation could cause high handover
delay
