Andrea:
I would be tempted to use pppd commands (in the UML guests) with pty arguments that \
consisted of ssh commands into the host machine. The pppd commands would be used to \
setup the virtual network whose links had various arbitrary packet loss rates and \
time delays. I would use tun/tap devices between the host and guests to control \
things and allow the pppd/pty embedded ssh commands to work.
I have written some articles about setting up VPNs using pppd/pty/ssh here:
http://www.hopelesscase.com/linuxnotes/ppp
Then you'd have to write a process that ran on the host and implemented the \
arbitrary delays and packet loss rates (which the ssh commands would be connecting \
to).

Hi all,
I?d use UML to emulate wireless LAN and mesh scenarios. In particular,
I?m interested in emulating links with different SNR hidden nodes and
using iwconfig/iwlist tools on VMs to analyze network status.
First of all, I?ll work with fixed nodes only, then, the next step will
be mobile nodes.
Can you help me? Do you have any suggestion about tools or patches I can
use to emulate WLAN?
Thanks,
andrea
