About the handover failure in the A2A4 and A3 algorithms and Tracing

[zzy 0_0]

Hello,

I have been modeling cellular networks using modeling of Petri Net, but recently my professor asked me to verify the model in simulations, so I have started studying NS3.

I am using the tutorial lena-x2-handover-measures to study.

The original lena-x2-handover-measures is a simulation that one User can perform a handover between two cells, but I don't think there was a handover failure tracing in this one, so I put in the tracing of the handover failure of ns-3 and ran it because I want to know how many out of for example 10 people have experienced a handover failure in the handover process by A2-A4 or A3 handover. However, even though there were no error in execution, but the result of the tracing I wrote was not seen.

I am not sure if the numbers of sample of the UE  for the handover is the cause or if the tracing I wrote not working is the cause. I will upload my simple code file in this page and , the part of added code is enclosed in a dotted line.

If you have any comments or advise, I would like to know about it and appreciate for that.
