802_11a low data rate

[Víctor Sánchez Agüero]

Hello,

I am connecting two LXC containers as explained in ns3-LinuxContainers using an ns3 simulated ad-hoc wireless network. 

I am simply reusing the example code "tap-wifi-virtual-machine.cc" 

Introducir código aquí...//

// We're going to use 802.11 A so set up a wifi helper to reflect that.

//

WifiHelper wifi;

wifi.SetStandard (WIFI_PHY_STANDARD_80211a);

wifi.SetRemoteStationManager ("ns3::ConstantRateWifiManager", "DataMode", StringValue ("OfdmRate54Mbps"));

//

// No reason for pesky access points, so we'll use an ad-hoc network.

//

WifiMacHelper wifiMac;

wifiMac.SetType ("ns3::AdhocWifiMac");

//

// Configure the physcial layer.

//

YansWifiChannelHelper wifiChannel = YansWifiChannelHelper::Default ();

YansWifiPhyHelper wifiPhy = YansWifiPhyHelper::Default ();

wifiPhy.SetChannel (wifiChannel.Create ());

//

// Install the wireless devices onto our ghost nodes.

//

NetDeviceContainer devices = wifi.Install (wifiPhy, wifiMac, nodes);

By using iperf, the maximum bandwidth I have is around 980 Kbps, quite far from what I expected. Do you find any configuration issues, or can you give an advice to improve this results?

Thanks in advance

Hello, everybody.

I have continued to look for the solution to this issue. Searching in the ns3 google group I found several users who face similar problems but there is no conclusive solution.

Supposedly, in real-time emulation, several components are involved and a wrong configuration may affect the performance. Please, could you share any script in which the TapBridge or RealTimeScheduler modules are used with Wireless technology?

Thanks in advance

Hi, I have faced the same problem. I got similar data with you. Have you found the solution finally?  🙏
