ORBIT-USER: Where can I find documentation about mobility emulation through spatial switching?

[Arinto Murdopo]

Yup, Kishore is right, madwifi in the virtual mobility using
iwpriv<http://www.orbit-lab.org/wiki/HowTo/virtualMobility>and madwifi
in spatial
switching implementation<http://www.orbit-lab.org/wiki/HowTo/virtualMobilitySS>are
different. Even the kernel versions are also different. In this case,
like what Kishore stated below, the iwpriv patch will not apply to the
madwifi in spatial switching implementation.

Is there any tools that can achieve similar effect as iwpriv (controlling
the rate of packet received or RSSI between 2 nodes) under this madwifi
driver under Click framework?

Thank you,

Arinto
