I am trying to simulate the effect of margin of handover (hysteresis) and time to trigger in LTE in NetSim. Does anyone know good research papers using simulators in this area? Thanks
If NetSim support LTE Lena module, then you can simulate LTE X2 handover easily. LTE Lena module is available in NS3. You can find LTE Lena module in NS3 website. There are many research papers regarding LTE Lena module. You can find in the Internet.
Yes, you can easily simulate LTE X2 handover in NetSim.
In NetSim the handover procedure is event-triggered. Each UE evaluates the RSRP/SNR measured from a neighbouring cell and checks if it ever becomes better than the RSRP/SNR measured from the serving cell.
The amount by which the neighbouring cell SNR is higher than the server cell SNR is known as Margin of Handover.
You can implement this in NetSim by measuring the SNR from every cell and then comparing with the serving cell SNR and initiate the handover procedure only when the difference is greater than the margin of handover.
I think currently in NetSim this value is zero, but it can be changed to say 3dB.
Hello Sai, thank you for your answer. I can get the SNR in the LTE_Calculate_Received_Power() in LTE-PHY.c. Can you please tell me where should I change the code for the handover modeling?
To continue, can we generate mobility through an external source (say MATLAB or another simulator) and use that mobility file in NetSim? I am thinking of doing this for LTE Handover optimization project.
