+WAVE is a system architecture for wireless-based vehicular communications,

+within |ns3|.  The focus is on the MAC layer and MAC extension layer
+defined by [ieee80211p]_.

+
+Model Description
+*****************
+
+WAVE is an overall system architecture for vehicular communications.
+The standards for specifying WAVE include a set of extensions to the IEEE
+802.11 standard, found in IEEE Std 802.11p-2010 [ieee80211p]_, and
+the IEEE 1609 standard set, consisting of four documents:  
+resource manager:  IEEE 1609.1 [ieee1609dot1]_,
+security services:  IEEE 1609.2 [ieee1609dot2]_,
+network and transport layer services:  IEEE 1609.3 [ieee1609dot3]_,
+and multi-channel coordination:  IEEE 1609.4 [ieee1609dot4]_.
+
+In |ns3|, the focus of the ``wave`` module is on the MAC layer.
+The key design aspect of WAVE-compilant MACs is that they allow
+communications outside the context of a basic service set (BSS).
+The literature uses the acronym OCB to denote "outside the context
+of a BSS", and the class ``ns3::OcbWifiMac`` models this in |ns3|. 
+Many management frames will not be used, but when used, the BSSID field 
+needs to be set to a wildcard BSSID value. 
+Management information is transmitted by what is called a vendor specific 
+action frame. 
+
+With these changes, the packet transmissions (for a moving vehicle) can
+be fast with small delay.  At the physical layer, the biggest difference is 
+to use the 5.9 GHz band with a channel bandwidth of 10 MHz.  These physical
+layer changes can make the wireless signal relatively more stable,
+without degrading throughput too much (ranging from 3 Mbps to 27 Mbps), 
+although 20 MHz channel bandwidth is still supported.
+
+The source code for the WAVE MAC models lives in the directory
+``src/wave``.
+
+The current code represents an interim capability to realize an
+802.11p-compliant device, but without the WAVE extensions (which
+are planned for a later patch).  In vehicular communications using
+WAVE, radios have the capability of switching between control and
+service channels, or using multiple radios.  These aspects are not
+yet modelled.  The WaveNetDevice modelled herein enforces that
+a WAVE-compliant physical layer (at 5.9 GHz) is selected, and 
+does not require any association between devices (similar to an 
+adhoc WiFi MAC), but is otherwise similar (at this time) to a
+WifiNetDevice.
+
+Design
+======
+
+In |ns3|, support for 802.11p involves the MAC and PHY layers.
+To use an 802.11p NetDevice, ``ns3::Wifi80211pHelper`` is suggested.
+
+MAC layer
+#########
+
+The classes used to model the MAC layer are ``ns3::OrganizationIdentifier``,
+``ns3::VendorSpecificActionHeader``, ``ns3::HigherDataTxVectorTag``,
+``ns3::WaveMacLow``, and ``ns3::OcbWifiMac``.
+
+The OrganizationIdentifier and VendorSpecificActionHeader are used to support 
+the sending of a Vendor Specific Action frame. The HigherDataTxVectorTag 
+and WaveMacLow are used to support higher control transmission parameters. 
+These classes are all used in OcbWifiMac.
+
+OcbWifiMac is very similar to AdhocWifiMac, with some modifications. 
+(|ns3| AdhocWifiMac class is implemented very close to the 802.11p OCB 
+mode rather than a real 802.11 ad-hoc mode. The AdhocWifiMac has no BSS 
+context that is defined in 802.11 standard, so it will not take time to 
+send beacon and authenticate.)
+
+1. SetBssid, GetBssid, SetSsid, GetSsid
+   these methods are related to 802.11 BSS context which is unused in OCB context.
+2. SetLinkUpCallback, SetLinkDownCallback
+   WAVE device can send packets directly, so the WiFi link is never down.
+3. SendVsc, AddReceiveVscCallback
+   WAVE management information shall be sent by vendor specific action frame, 
+   and it will be called by upper layer 1609.4 standard to send WSA
+   (WAVE Service Advertisement) packets or other vendor specific information.
+4. SendTimingAdvertisement (not implemented)
+   Although Timing Advertisement is very important and specifically defined in 
+   802.11p standard, it is not useful in a simulation environment. 
+   Every node in |ns3| vehicular simulation is assumed to be already time 
+   synchronized (perhaps by GPS).
+5. ConfigureEdca
+   This method will allow the user to set EDCA parameters of WAVE channeles 
+   including CCH ans SCHs. And the OcbWifiMac itself also uses this method 
+   to configure default 802.11p EDCA parameters.
+6. WILDCARD BSSID
+   The WILDCARD BSSID is set to "ff:ff:ff:ff:ff:ff".
+   As defined in 802.11-2007, a wildcard BSSID shall not be used in the
+   BSSID field except for management frames of subtype probe request. But Adhoc 
+   mode of |ns3| simplifies this mechanism:  when stations receive packets, 
+   packets regardless of BSSID will be forwarded up to the higher layer. 
+   This process is very close 
+   to OCB mode as defined in 802.11p-2010, in which stations use the wildcard 
+   BSSID to allow the higher layer of other stations to hear directly.
+7. Enqueue, Receive
+   The most important methods are send and receive methods. According to the 
+   standard, we should filter the frames that are not permitted. However here we 
+   just identify the frames we care about; the other frames will be discarded.
+
+PHY layer
+#########
+Actually, no modification or extension happens in the |ns3| PHY layer
+corresponding to this model.
+In the 802.11p standard, the PHY layer wireless technology is still 80211a OFDM with 10MHz channel width,
+so Wifi80211pHelper will only allow the user to set the standard 
+to WIFI_PHY_STANDARD_80211_10MHZ or WIFI_PHY_STANDARD_80211_20MHZ
+(WIFI_PHY_STANDARD_80211a with 20MHz is supported, but not recommended.)
+The maximum station transmit power and maximum permitted EIRP defined in 
+802.11p is larger 
+than that of WiFi, so transmit range can normally become longer than 
+usual WiFi.  However, this feature will 
+not be implemented. Users who want to obtain longer range should configure 
+attributes "TxPowerStart", 
+"TxPowerEnd" and "TxPowerLevels" of the YansWifiPhy class.
+
+Scope and Limitations
+=====================
+
+1. Does the model involve vehicular mobility of some sort?
+
+Vehicular networks involve not only communication protocols, but also 
+a communication environment 
+including vehicular mobility and propagation models. Because of specific 
+features of the latter, the protocols need to change. The MAC layer model 
+in this 
+project just adapts MAC changes to vehicular environment. However this model 
+does not involve any
+vehicular mobility with time limit. Users can use any mobility model in |ns3|, 
+but should understand that vehicular mobility is out of scope for the
+current WAVE module.
+
+2. Is this model going to use different propagation models?
+
+Referring to the first issue, some more realistic propagation models 
+for vehicualr environment
+are suggested and welcome. And some existing propagation models in |ns3| are 
+also suitable. 
+Normally, users can use Friis, Two-Ray Ground, and Nakagami models. 
+
+3. Are there any vehicular application models to drive the code?
+
+About vehicular application models, SAE J2375 depends on WAVE architecture and
+is an application message set in US; CAM and DENM in Europe between network 
+and application layer, but is very close to application model. The BSM in 
+J2375 and CAM send alert messages that every 
+vehicle node will sent periodicity about its status information to 
+cooperate with others. 
+Fow now, a vehicular application model is not within scope.

+
+Helpers
+=======
+The helpers include ``ns3::NqosWaveMacHelper``, ``ns3::QosWaveMacHelper``, 
+``ns3::Wifi80211pHelper`` and ``ns3::WaveHelper``. Wifi80211pHelper is used 
+to create 
+802.11p devices that follow the 802.11p-2010 standard. WaveHelper is 
+used to create WAVE devices that follow the 802.11p-2010 and 1609.4-2010 
+standards which are the MAC and PHY layers of the WAVE architecture. 
+The relation of them is described as below:

+      Wifi80211pHelper     QosWaveMacHelper  NqosWaveHelper
+
+Although Wifi80211Helper can use any subclasses inheriting from 
+WifiMacHelper, we force users to use subclasses inheriting from 
+QosWaveMacHelper or NqosWaveHelper.
+
+Although the functions of WiFi 802.11p device can be achieved by 
+WaveNetDevice's ContinuousAccess assignment, Wifi80211pHelper is recommeneded
+if there is no need for multiple channel operation.
+Usage is as follows:
+
+::
+
+    NodeContainer nodes;
+    NetDeviceContainer devices;
+    nodes.Create (2);
+    YansWifiPhyHelper wifiPhy = YansWifiPhyHelper::Default ();
+    YansWifiChannelHelper wifiChannel = YansWifiChannelHelper::Default ();
+    wifiPhy.SetChannel (wifiChannel.Create ());
+    NqosWave80211pMacHelper wifi80211pMac = NqosWaveMacHelper::Default();
+    Wifi80211pHelper 80211pHelper = Wifi80211pHelper::Default ();
+    devices = 80211pHelper.Install (wifiPhy, wifi80211pMac, nodes);
+
+APIs
+====
+
+The 802.11p device can allow the upper layer to send different information
+over Vendor Specific Action management frames by using different
+OrganizationIdentifier fields to identify differences.
+
+1. already create a Node object and WifiNetDevice object
+2. define an OrganizationIdentifier
+
+::
+
+   uint8_t oi_bytes[5] = {0x00, 0x50, 0xC2, 0x4A, 0x40};
+   OrganizationIdentifier oi(oi_bytes,5);
+
+3. define a Callback for the defined OrganizationIdentifier
+
+::
+
+   VscCallback vsccall = MakeCallback (&VsaExample::GetWsaAndOi, this);
+
+4. OcbWifiMac of 802.11p device registers this identifier and function
+
+::
+
+      Ptr<WifiNetDevice> device1 = DynamicCast<WifiNetDevice>(nodes.Get (i)->GetDevice (0));
+      Ptr<OcbWifiMac> ocb1 = DynamicCast<OcbWifiMac>(device->GetMac ());
+      ocb1->AddReceiveVscCallback (oi, vsccall);
+
+5. now one can send management packets over VSA frames
+
+::
+
+      Ptr<Packet> vsc = Create<Packet> ();
+      ocb2->SendVsc (vsc, Mac48Address::GetBroadcast (), m_16093oi);
+
+6. then registered callbacks in other devices will be called.
+
+Attributes
+==========
+
+The current classes do not provide any additional attributes beyond those
+in the WiFi module.
+
+Output
+======
+
+The current classes provide output of the same type as WiFi devices;
+namely, ASCII and pcap traces, and logging output.  The WAVE logging
+components can be enabled globally via the call to
+
+::
+  
+  Wifi80211pHelper::EnableLogComponents ();
+
+
+Advanced Usage
+==============
+
+To be defined.
+
+Examples
+========
+
+A basic example exists called ``wave-simple-80211p.cc``.
+This example shows basic construction of an 802.11p node.  Two nodes
+are constructed with 802.11p devices, and by default, one node sends a single
+packet to another node (the number of packets and interval between
+them can be configured by command-line arguments).  The example shows
+typical usage of the helper classes for this mode of WiFi.
+
+Troubleshooting
+===============
+
+To be defined.
+
+Validation
+**********
+
+A single test suite named ``wifi-80211p-ocb`` is defined.  This test
+case consists of a stationary node and a mobile node.  The mobile
+node moves towards the stationary mode, and time points are checked
+at which time the physical layer starts to receive packets (and
+whether the MAC becomes associated, if applicable).  The same physical
+experiment is repeated for normal WiFi NetDevices in AP/STA mode, in
+Adhoc mode, and the new OCB mode.
