Detailed Description

The Wifi MAC high model for a non-AP STA in a BSS.

The state machine is as follows:

---------       --------------                                         -----------
| Start |       | Associated | <-------------------------        ----> | Refused |
---------       --------------                           |      /      -----------
   |              |   /------------------------------\   |     /
   \              v   v                              |   v    /
    \    ----------------     ---------------     -----------------------------
     \-> | Unassociated | --> | Wait Beacon | --> | Wait Association Response |
         ----------------     ---------------     -----------------------------
               \                  ^     ^ |              ^    ^ |
                \                 |     | |              |    | |
                 \                v      -               /     -
                  \    -----------------------          /
                   \-> | Wait Probe Response | --------/
                       -----------------------
                               ^ |
                               | |
                                -

Notes:

The state 'Start' is not included in MacState and only used for illustration purpose.
The Unassociated state is a transient state before STA starts the scanning procedure which moves it into either Wait Beacon or Wait Probe Response, based on whether passive or active scanning is selected.
In Wait Beacon and Wait Probe Response, STA is gathering beacon or probe response packets from APs, resulted in a list of candidate AP. After the respective timeout, it then tries to associate to the best AP (i.e., best SNR). STA will switch between the two states and restart the scanning procedure if SetActiveProbing() called.
In the case when AP responded to STA's association request with a refusal, STA will try to associate to the next best AP until the list of candidate AP is exhausted which sends STA to Refused state.
- Note that this behavior is not currently tested since ns-3 does not implement association refusal at present.
The transition from Wait Association Response to Unassociated occurs if an association request fails without explicit refusal (i.e., the AP fails to respond).
The transition from Associated to Wait Association Response occurs when STA's PHY capabilities changed. In this state, STA tries to reassociate with the previously associated AP.
The transition from Associated to Unassociated occurs if the number of missed beacons exceeds the threshold.

MacTx: A packet has been received from higher layers and is being processed in preparation for queueing for transmission.
Callback signature: ns3::Packet::TracedCallback
MacTxDrop: A packet has been dropped in the MAC layer before being queued for transmission. This trace source is fired, e.g., when an AP's MAC receives from the upper layer a packet destined to a station that is not associated with the AP or a STA's MAC receives a packet from the upper layer while it is not associated with any AP.
Callback signature: ns3::Packet::TracedCallback
MacPromiscRx: A packet has been received by this device, has been passed up from the physical layer and is being forwarded up the local protocol stack. This is a promiscuous trace.
Callback signature: ns3::Packet::TracedCallback
MacRx: A packet has been received by this device, has been passed up from the physical layer and is being forwarded up the local protocol stack. This is a non-promiscuous trace.

Initialize() implementation.

This method is called only once by Initialize(). If the user calls Initialize() multiple times, DoInitialize() is called only the first time.

Subclasses are expected to override this method and chain up to their parent's implementation once they are done. It is safe to call GetObject() and AggregateObject() from within this method.
