57 * In WAVE module, there is no net device class named like "Wifi80211pNetDevice",
58 * instead, we need to use Wifi80211pHelper to create an object of
59 * WifiNetDevice class.
60 *
61 * usage:
62 * NodeContainer nodes;
63 * NetDeviceContainer devices;
64 * nodes.Create (2);
65 * YansWifiPhyHelper wifiPhy;
66 * YansWifiChannelHelper wifiChannel = YansWifiChannelHelper::Default ();
67 * wifiPhy.SetChannel (wifiChannel.Create ());
68 * NqosWaveMacHelper wifi80211pMac = NqosWave80211pMacHelper::Default();
69 * Wifi80211pHelper wifi80211p = Wifi80211pHelper::Default ();
70 * devices = wifi80211p.Install (wifiPhy, wifi80211pMac, nodes);
71 *
72 * The reason of not providing a 802.11p class is that most of modeling
73 * 802.11p standard has been done in wifi module, so we only need a high
74 * MAC class that enables OCB mode.
