Get Associated Access point address

[Chandrani ray chowdhury]

Does anybody help me to get the associated access point address of a wifi node in ns3

[Chandrani ray chowdhury]

below is my code, but it shows no association.

can somebody please help me.

void GetAssociatedAccessPointID(Ptr<Node> node1)

{

        uint32_t assoid;

Ptr<NetDevice> dev1 = node1->GetDevice(0);

Ptr<WifiNetDevice> wifi_dev1 = DynamicCast<WifiNetDevice>(dev1);

Mac48Address staAdrs = Mac48Address::ConvertFrom(wifi_dev1->GetAddress());

std::cout<<"mac address=====of station "<<staAdrs<<std::endl;

Ptr<WifiRemoteStationManager> wr = wifi_dev1->GetRemoteStationManager();

uint32_t i,j=0;

Mac48Address adrs;

Ptr<WifiNetDevice> wifi_apdev1;

for(i=0;i<numDAUs;i++)

{

wifi_apdev1= DynamicCast<WifiNetDevice>(m_DAUs.Get(i)->GetDevice(0));

Mac48Address adrs = Mac48Address::ConvertFrom(wifi_apdev1->GetAddress());

std::cout<<"mac address====="<<adrs<<std::endl;

if(wr->IsAssociated(adrs))

{

j=i;

break;

}

}

assoid=j;

std::cout<<"associated id==="<<assoid<<std::endl;

}

Can you also share the error message that you encountered while compiling or running the script ?

The code does not show any error, but always shows the association id is zero, while from  pcapTrace I found that will be 1 (Mac address: 00:00:00:00:00:02). 1 is the node id
