- Abstract
This article discusses the need for smooth hand offs between Internet attachment points in mobile IPv6 networks. This wireless access challenge is resulted from the increasing number of Wi-Fi-compatible mobile devices. To confirm address uniqueness in a new domain, mobile nodes must run duplicate address detection (DAD), which is a time-consuming process. The Proactive DAD approach uses topology information and layer-2 signals to predict the network domains prior to or in parallel with layer-3 hand offs. Experimental results show that P-DAD can significantly reduce both hand-off latency and packet loss.
