Video Data in HWMP

[A G]

Hi, 

When I transmit video frames in Layer-3 Routing (AODV,OLSR,etc) over 802.11ac network packet loss is around 7% using onoffApplication. However When I use the same over HWMP mesh layer2 routing protocol packet loss is 99%. What is wrong here? Do I have to set something in HWMP (reactive) for video/multimedia traffic data?

Following reference : I used for video data paramters

Campo Muñoz, Wilmar Yesid & Astaiza Hoyos, Evelio & Muñoz-Sanabria, Luis. (2017). Traffic modelling of the video-on-demand service through NS-3. DYNA. 84. 55-64. 10.15446/dyna.v84n202.61650.

Sample code : simtime=180 sec

1 Distance between wifi nodes 250 meters grid size=4x4 16 nodes

2. Tx power 30dbm

3. Tx Gain 9.0 dbi

4. Sink code:

uint16_t port = 9;

std::string dataRate = "331776kbps"; 

  uint32_t packetSize = m_packetSize; //1500

      //1 Sink

       PacketSinkHelper sink0 ("ns3::UdpSocketFactory", InetSocketAddress (Ipv4Address::GetAny (), port));

       ApplicationContainer serverApp0 = sink0.Install (nodes.Get (0));

      serverApp0.Start (Seconds (1.0));

      serverApp0.Stop (Seconds (180));

5.//Source code:

OnOffHelper onoff ("ns3::UdpSocketFactory", Address (InetSocketAddress (interfaces.GetAddress (0), port)));

     onoff.SetConstantRate(dataRate, (uint32_t)packetSize);

    onoff.SetAttribute("OffTime",StringValue("ns3::LogNormalRandomVariable[Mu=0.4026|Sigma=0.0352]"));

   onoff.SetAttribute("OnTime",StringValue("ns3::WeibullRandomVariable[Shape=10.2063|Scale=57480.9]"));

    onoff.SetAttribute("MaxBytes",UintegerValue(10989173));

    onoff.SetAttribute ("StartTime", TimeValue (Seconds (1.000000)));

      ApplicationContainer apps = onoff.Install (nodes.Get (15));

      apps.Start (Seconds (2.0));

      apps.Stop (Seconds (180));

Thanks
