[ns] How to Simulate Wireless Links (error characteristics of)

[Gaurav Navlakha <navlakha@students.uiuc.edu>]

Hi,

I'm using NS v2.1b8a.

I have a basic question. How do I simulate a wireless link (with
wireless link characteristics such as interference errors, errors due to
background noise, etc..)?

I don't want mobility-induced errors. I just want a wired +
one-hop-wireless network connected by some Base Station.

Will the links between the Base station (BS(0))
and the 'mobile' nodes show some error characteristics that are
different from the link characteristics of the wired links (between W(0)
and BS(0)), if I just remove all the "setdest" statements from the
mobility scenario file (../mobility/scene/scen-3-test)?

In other words, will (random) transmission errors be introduced, and
cause packet loss over the 'wireless' links even when there is no
movement of nodes?

If yes, then where have these inbuilt error characteristics of wireless
link been implemented? How can these be changed?

Alternatively, is it possible to use the "ErrorModel" class to introduce
error characteristics on a wired link so as to simulate a wireless link?

Any help will be truly appreciated.

Thanks,
Gaurav.
