Hi!

1) Mobility calculation is done by the C++ half of the
mobilenode class in "mobilenode.{h.cc}.
The speed parameter is also accessible from
TCL via the bound TCL variable "speed_"

2) As far as I know (please correct me if I'm wrong!)
there is no SIR measurement already implemented.
Packets are just missed, received successfully or collide
with other packets based on their signal strength.
The signals of several packets with a low signal strength
don't accumulate and increase the noise around a node, which
is currently receiving a packet.
If you want to implement SIR measurement, my suggestion is to 
put it into the mac-802.11 class, because the decision whether a
packet can be received successfully and the collision
detection is done there.

Bye

Felix
