How to set up iperf for roaming test???

[wahaha]

Halo,

I have installed a network measurement tool, which is called iperf:
http://dast.nlanr.net/Projects/Iperf/

Currently, I am trying to do a roaming test among 2 laptops and one desktop by using called Dynamic Mobile IP and as well as a OLSR routing protocol.

I have plan to do a handoff throughput measurement (for UDP) among the 3 nodes as one laptop from move from one subnet to another subnet.

I have refer to the documentation of iperf, as below:
http://dast.nlanr.net/Projects/Iperf...docs_1.7.0.php

But i am still not sure how to set up for the handoff measurement. Can someone guide me how to setup it up?

Is it same like the example "Multicast" as from the above documentation link???

If you know it please drop your message here. Your helps are much needed.

Thank you.
