[omnetpp] Help with umts simulation

[Labrini]

Hello everyone,

I am trying to make a simulation of a umts network with two servers and
some UEs. I want to make a network that will use WCDMA and the UEs will
use different services(either conversational either web services). I
use omnet 3.3 because I couldn't install INET.Is there any example of
UMTS that could help me? I have a big problem writing the source code.

Thanks in advance!!

Hi all
Let's suppose I want to create a customized channel such that it
performs some non standard tasks.

I checked on INET and I found a customized channel,
ThruputMeteringChannel, derived from the cBasicChannel class as it is
supposed to be (I think...)
Problem with that is the way the channel is indeed put to use. A
top-level simple module, ChannelInstaller, is created and its duty is to
run over the whole list of channels in the system and (eventually,
because some filtering could be applied) substitute the standard channel
definition with
ThruputMeteringChannel.
Provided that it works, and of course it does, and that I want to
substitute just a very small fraction of the channels, isn't there an
easier way to accomplish this? Any ways to specify the customized
channel in the ned file(s) as it is supposed to be?

Thanks a lot,
Regards,
Michele

That would be indeed the correct solution, and it has been implemented in
the upcoming 4.0 release. Until then, well, there're only
ChannelInstaller-like solutions...
