Experimental evaluation of IEEE 802.11b and mobile IPv6 hand-off times

This paper reviews the use of MIPv6 to support mobility between independent 802.11b-attached IPv6 subnets, and uses a wireless testbed to experimentally measure how long an end-to-end IP path is disrupted when a MIPv6 node shifts from one subnetwork to another (handoff latency). We also measure 802.11b handoff independent of MIPv6. Using out results, we evaluate the likely performance impact of MIPv6 handoff on a common webcam application and bulk TCP data transfers.
