IEEE 802.11abg Model

Features

The IEEE 802.11abg radio model provides the following set of features:

Supports flow control.
Supports the following waveform modes and data rates with the appropriate timing:
802.11b (DSS rates: 1, 2, 5.5 and 11 Mbps)
802.11a/g (OFDM rates: 6, 9, 12, 18, 24, 36, 48 and 54 Mbps)
802.11b/g (DSS and OFDM rates)
Supports only the DCF channel access function. PCF and beacon transmissions are not supported.
Supports both unicast and broadcast transmissions. Unicast transmissions include the ability to emulate control message (RTS/CTS) behavior as well as retries without actually transmitting the control messages or the re-transmission of the data message. The emulation of unicast does not replicate exponential growth of the contention window as a result of detected failures.
Supports Wi-Fi multimedia (WMM) capabilities. The initial implementation supports the ability to classify four different traffic classes (Background, Best Effort, Video and Voice) where the higher priority classes (voice and video) are serviced first.
Supports user defined Packet Completion Rate curves as a function of SINR.
Default curves are provided for each of the supported 802.11 modulation and data rate combinations. Default curves are based on theoretical equations for determining Bit Error Rate (BER) in an Additive White Gaussian Noise (AWGN) channel.
The IEEE 802.11abg radio model does adjust the interference on a per packet basis based on detected collisions and as such supports negative SINR values as can be seen in the default curves

Packet Completion Rate

The IEEE 802.11abg Packet Completion Rate is specified as curves defined via XML. The curve definitions are comprised of a series SINR values along with their corresponding probability of reception. A curve definition must contain a minimum of two points with one SINR representing POR = 0 and one SINR representing POR = 100. Linear interpolation is preformed when an exact SINR match is not found.

Specifying a packet size (<table> attribute pktsize) in the curve file will adjust the POR based on received packet size. Specifying a pktsize of 0 disregards received packet size when computing the POR.

The POR is obtained using the following calculation when a non-zero pktsize is specified:

POR = POR0^(S1/S0)

Where,

POR0 is the POR value determined from the PCR curve for the given SINR value
S0 is the packet size specified in the curve file (pktsize)
S1 is the received packet size

The emulator provides the following default PCR curve definition.

The below statistics can be accessed using emanesh.

Name	Type	Clearable	Description
avgDownstreamProcessingDelay0	float	yes	Average downstream processing delay
avgDownstreamProcessingDelay1	float	yes	Average downstream processing delay
avgDownstreamProcessingDelay2	float	yes	Average downstream processing delay
avgDownstreamProcessingDelay3	float	yes	Average downstream processing delay
avgProcessAPIQueueDepth	double	yes	Average API queue depth for a processUpstreamPacket, processUpstreamControl, processDownstreamPacket, processDownstreamControl, processEvent and processTimedEvent.
avgProcessAPIQueueWait	double	yes	Average API queue wait for a processUpstreamPacket, processUpstreamControl, processDownstreamPacket, processDownstreamControl, processEvent and processTimedEvent in microseconds.
avgTimedEventLatency	double	yes
avgTimedEventLatencyRatio	double	yes	Average ratio of the delta between the scheduled timer expiration and the actual firing over the requested duration. An average ratio approaching 1 indicates that timer latencies are large in comparison to the requested durations.
avgUpstreamProcessingDelay0	float	yes	Average upstream processing delay
avgUpstreamProcessingDelay1	float	yes	Average upstream processing delay
avgUpstreamProcessingDelay2	float	yes	Average upstream processing delay
avgUpstreamProcessingDelay3	float	yes	Average upstream processing delay
