Compound Module Ieee80211RadioMedium

Package: inet.physicallayer.ieee80211.packetlevel
File: src/inet/physicallayer/ieee80211/packetlevel/Ieee80211RadioMedium.ned

This radio medium model is part of thee IEEE 802.11 physical layer model. It must be used in conjunction with the Ieee80211Radio model or other derived models.

This model provides sensible default values for the radio medium parameters to be used in IEEE 802.11 simulations.

Extends:

Name	Type	Description
RadioMedium	compound module	The medium model describes the shared physical medium where communication takes place. It keeps track of radios, noise sources, ongoing transmissions, background noise, and other ongoing noises. The medium computes when, where and how transmissions and noises arrive at receivers. It also efficiently provides the set of interfering transmissions and noises for the receivers.

Known subclasses:

Name	Type	Description
Ieee80211DimensionalRadioMedium	compound module	This radio medium model uses dimensional transmission power (that changes over time and/or frequency) in the analog representation. It must be used in conjunction with the Ieee80211DimensionalRadio model.
Ieee80211ScalarRadioMedium	compound module	This radio medium model uses scalar transmission power in the analog representation. It must be used in conjunction with the Ieee80211ScalarRadio model.

Parameters:

Name	Type	Default value	Description
physicalEnvironmentModule	string	"physicalEnvironment"	module path of the physical environment model
propagationType	string	"ConstantSpeedPropagation"	submodule type parameters
pathLossType	string	"FreeSpacePathLoss"	NED type of the path loss model
obstacleLossType	string	""	NED type of the obstacle loss model
analogModelType	string		NED type of the analog model
backgroundNoiseType	string	""	NED type of the background noise model
mediumLimitCacheType	string	"MediumLimitCache"	NED type of the medium limit cache model
neighborCacheType	string	""	NED type of the neighbor cache model
communicationCacheType	string	"VectorCommunicationCache"	NED type of the communication cache model
rangeFilter	string	""	filter parameters that control when radio frames are sent to receiver radios
radioModeFilter	bool	false	when enabled the radio medium doesn't send radio frames to a radio if it's neither in receiver nor in transceiver mode
listeningFilter	bool	false	when enabled the radio medium doesn't send radio frames to a radio if it listens on the channel in incompatible mode (e.g. different carrier frequency and bandwidth, different modulation)
macAddressFilter	bool	false	when enabled the radio medium doesn't send radio frames to a radio if it the destination mac address differs
recordCommunicationLog	bool	false	logging parameters
