How to add wall effect in 802.11n WLAN simulation

[sumon Debnath]

Hello Everyone
If there is a wall between an access- point and client then throughput will drop certain percent. How can i add this effect in 802.11n WLAN ns3 simulation. Can anyone please help me.

Hi,

You need to create/use the corresponding propagation loss model that takes into consideration the effect of the wall. 

There is the Buildings model (Hybrid or OH) https://www.nsnam.org/docs/doxygen/classns3_1_1_buildings_propagation_loss_model.html

that you can use for such scenarios.

Thank you very much. I am new user in ns3. How can I create the following scenario in ns3 simulation to reflect the effect of wall. Can you give me some ideas to model this scenario.

with best regards

Dear Konstantinos

thank you for yor valuable information. I have created Building propagation loss model. But I can not partition room of different size to model of simulation environment. Can you please help me? Is this building propagation loss model work with  constant rate manager (HtMcs5)?

Best Regards

Hello Konstantinos

Suppose that the link speed between an access point and its client is 120 Mbps at some distance between them. It there is a concrete wall between them then this link speed drops certain percent (Around 15% link speed drop per concrete wall is found by measurement). So how can I evaluate this effect in ns-3 simulation just considering wall loss. I tried with Hybrid Building Propagation loss mode but it does to give expected result.

Another question is it possible to create wireless link with specific speed between wifi Access point and its associated client in ns3?

Please help me if it can be possible.
