Handover in Wifi Networks

[Ayub Afridi]

Hello Everyone!! I have a specific question related to the WIFI network in Ns-3.

"Do any of you have any knowledge of WIFI modules in NS-3? 

is it possible to do the handover or shifting of AP's connections between Users? just like in real-time we face when we move from one AP range to another?

Please Help and share some examples or documents etc.

Hello, 

I work with a WIFI module in NS-3, I have never done it before, but if I was to do that, here is what I would suggest:
1. You have to implement mobility model, where STAs move across the network and APs have constant mobility (STA and AP in the same network)

2. There is a way that you can measure RSS (Received Signal Strenght) in Dbm in WIFI Model, you can calculate the signal strength you are receiving from multiple AP.

3. Decide to issue an association request to the AP with the strongest signal strength (since there is no authentication as far as I know for WIFI module in NS-3)

Check this example .

Thank you very much for the immediate Reply @ Geovany Teca.

Yes, I am doing the same thing which you mentioned. I have already done point 1 and it's more complex.

point 2 and 3 i will check with the example code you provided and then i will come back to you.

I also looking for some solution in this case. Could you able to solve this issue?

I think it's the best and most simple way to make a handover with RSS value.
