not all sources work !

[N.omar]

Hello All 

I am using  Omnet4.3 with inetmanet 2.0 

I build a scenario of adhoc network with total number hosts 50 .  and i assign 16 of them to be sources and exchange data between each other using TCPsession application.

also I have used seed-set to get differenet topologies each time , my aim is to get result about throughput and I have used throughMeter for this . 

First : when i run my scenario with some seed the simulation end quickly . and the results are being ZERO .

secound : for another seeds the scenario work fine (even it is slow ) until simulation time limit reach , But the data exchange only be between 2 or 4 or 6 of the sources , not all the  (16 .sources ) sources send the data  

 the pictures  explain the results  of first and second 

 . Also i will attach my .ned and ini files 

 

How I can solve the problem by make all the sources  work ! and does their behavior is normal ?!

Thank you
