/*
 * In WAVE module, there is no net device class named like "Wifi80211pNetDevice",
 * instead, we need to use Wifi80211pHelper to create an object of
 * WifiNetDevice class.
 *
 * usage:
 *  NodeContainer nodes;
 *  NetDeviceContainer devices;
 *  nodes.Create (2);
 *  YansWifiPhyHelper wifiPhy;
 *  YansWifiChannelHelper wifiChannel = YansWifiChannelHelper::Default ();
 *  wifiPhy.SetChannel (wifiChannel.Create ());
 *  NqosWaveMacHelper wifi80211pMac = NqosWave80211pMacHelper::Default();
 *  Wifi80211pHelper wifi80211p = Wifi80211pHelper::Default ();
 *  devices = wifi80211p.Install (wifiPhy, wifi80211pMac, nodes);
 *
 * The reason of not providing a 802.11p class is that most of modeling
 * 802.11p standard has been done in wifi module, so we only need a high
 * MAC class that enables OCB mode.
