How to achieve high throughputs?

[tagorepothuneedi]

Hello

I'm trying to simulate the 2.4Ghz,5Ghz mesh networks in modes a,n,ac. But I'm not able to get high throughputs like 200 or 300Mbps. I tried decreasing the distance between stations, increasing the txpower ,changing the propagation models etc . But nothing is seems to impact the speeds.I'm only seeing 20-30Mbps or less depending upon the mentioned parameters.

How can I simulate a high throughput wifi mesh network? any other parameters which I should look at? FYI the topology is very simple one in linear way using two or three stations.

Perhaps some changes are required in Wmediumd but I have a question: could you give me a pointer where nodes achieve such high throughputs? We know that they support 300, 450MBps, theorycally. However, I don't know of any work where the nodes achieve even 1/6 of the maximum theoretical throughput supported by IEEE 802.11s.

Yes I saw in the simulation itself once, the high throughputs of 360-430Mbps. But I'm not able recreate that scenario no matter what parameters I tune. The tx,rx bitrates and MCS are seen low all the time even if the signal strength is good.

Would you mind to share some work (e.g. research papers, real experiments) that show that it is possible to reach 300Mbits in 802.11s?

Hi , I was reading some online articles and found the using MIMO links higher throughputs can be achieved. Is there a way to incorporate that in Mininet-wifi? https://ieeexplore.ieee.org/abstract/document/4215856?casa_token=nMInHHpDNvsAAAAA:GYGbdx_WKZJBuoha0YIZpgVi2b8qBDtXhTtkVlUJ7ZpJJyuWsEUFTv7wHfYos66QpdnNB49iCg

Dear,

Can you be more specific? What is your definition for "high throughputs"? Based on which work and which values you are arguing that you should achieve higher throughputs in wireless mesh?? You're arguing that it should achieve 300Mbs but you didn't give any pointer that could support your claim.

Hi,By high throughput I mean high bandwidths/data rate.I know you had already mentioned that only 1/6 of bandwidth is practical in real time. Still I'm looking for any articles, papers which can show prove high bandwidth is achievable in mesh and I'm thinking to simulate in Mininet scenario if I can. Theoretically 802.11ac supports upto 1.3Gbps ,1/6 of 1.3 is ~200Mbps ,so practically I should see 200Mbps in a simulation and I'm not seeing the expected results.So I want to know what are the limitations in Mininet or the real world scenarios that are causing this loss even when signal strength,air quality , etc are good. Please let me know if I'm moving in wrong direction or help me with some information/articles/links that helps me set in the right way. Thanks
