This paper presents NDPR

a scheme of low-latency mobile IPv6 handoff for IEEE 802.11 wireless LANs.Without using L2 triggers

NDPR employs Nonuniform Detection Model to reduce the latency and the cost of L2 handoff detection.Furthermore

NDPR reduces the latency of mobility detection by making the map between IP address and MAC address

and reduces the latency of Care-of Address (CoA) configuration using CoA pre-registering mechanism.The simulation indicates that NDPR can lower the MIPv6 handoff latency efficiently and outperforms its counterparts.
