Starting with MiXiM: A step-by-step guide

[Marcos Fagundes Caetano]

Hi,

It is my first time trying to work with OMNETpp simulator.

I'm very frustrated, because I can't make the first example works in my computer.

I'm trying to do the first tutorial example named: Starting with MiXiM: A step-by-step guide

http://sourceforge.net/apps/trac/mixim/wiki/StepByStep

I was able to compiled the OMNET source code (4.3) and also the mixim (from git). All mixim and OMNET examples are working perfectly.

When I try to run my project, the eclipse shows the following message:

Error in module (cCompoundModule) MeuProjeto.node[0] (id=4) during network setup: Submodule mobility: no module type named `BaseMobility' found that implements module interface inet.mobility.IMobility (not in the loaded NED files?), at ../minix/src/modules/node/WirelessNode.ned:32.

Someone could tell me what is going on? I just want to create a simple topology in order to evaluate the IEEE 802.11 implementation. I would like to make some changes and run some different simulations scenarios.

Best regards.

Caetano.

Hi Caetano!

I'm not a user of MiXiM but, apparently, they have modeled interfaces for mobility (IMobility) just as INETMANET does. This is a recent change and, probably, the tutorial you are following is outdated.
What you have to do is to go to your network NED file and replace "BaseMobility" with some implementation of the IMobility interface that, I guess, are located at $MIXIM/src/modules/mobility. StationaryMobility should give a basic mobility model (i.e., static nodes).

Hope it helps!
Arliones.

Marcos,

   could you send the code in order I can test here?

Hi, Arliones,

Thank you very much for the reply. I'm very happy to know that you are participating in this community!

Your advice was correct. When I created the scenario using the wizard tutorial, the default code generated for mobility was:

**.node[*].mobilityType = "BaseMobility"
**.node[*].mobility.debug = false
**.node[*].mobility.updateInterval = 0.1s
**.node[0].mobility.initialX = 150m
...

I just changed to:

**.node[*].mobilityType = "StationaryMobility"
**.node[*].mobility.debug = false
**.node[*].mobility.initFromDisplayString = false

Now, everything is working perfectly.

Best regards.

Caetano.

Hi, Ivo.

Thank you for your reply.

I already solved the problem. I changed the default mobility code parameters to the code below.

**.node[*].mobilityType = "StationaryMobility"
**.node[*].mobility.debug = false
**.node[*].mobility.initFromDisplayString = false

Thank you for your interest in helping me.

Best regards.

Caetano.
