OriginatorQosMacDataService¶

Package: inet.linklayer.ieee80211.mac.originator

compound module OriginatorQosMacDataService

Implements the MAC data service for the originator (sender) side in IEEE 802.11 QoS networks. Extends the basic MAC data service with QoS capabilities including MSDU aggregation (A-MSDU) and MPDU aggregation (A-MPDU). Processes outgoing frames by assigning sequence numbers, performing aggregation, and fragmentation based on configured policies. Follows the MAC data plane architecture described in IEEE 802.11 standard.

Used in compound modules¶

Name	Type	Description
Hcf	compound module	Implements the HCF (Hybrid Coordination Function) for IEEE 802.11.

Extends¶

Name	Type	Description
Module	compound module	Base module for all INET compound modules.

Parameters¶

Name	Type	Default value	Description
displayStringTextFormat	string	“”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information

Properties¶

Name	Value	Description
class	OriginatorQosMacDataService
display	i=block/fork

Signals¶

Name	Type	Unit	Description
packetAggregated	inet::Packet
packetFragmented	inet::Packet

Statistics¶

Name	Title	Source	Record	Unit	Interpolation Mode	Description
packetAggregated	packets aggregated		count
packetFragmented	packets fragmented		count

Unassigned submodule parameters¶

Name	Type	Default value	Description
msduAggregationPolicy.displayStringTextFormat	string	“”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
msduAggregationPolicy.subframeNumThreshold	int	-1	Minimum number of subframes needed to compose an A-MSDU. (-1 means it won’t be checked)
msduAggregationPolicy.aggregationLengthThreshold	int	-1	The minimum length for an aggregated payload necessary to create an A-MSDU (-1 means it won’t be checked).
msduAggregationPolicy.maxAMsduSize	int	4065	-1 means infinity
msduAggregationPolicy.qOsCheck	bool	true	Turns on/off the check of the presence of the QoS flag (false means off – this is needed for aggregation in DCF mode).
mpduAggregationPolicy.displayStringTextFormat	string	“”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
fragmentationPolicy.displayStringTextFormat	string	“”	Determines the text that is written on top of the submodule, supports displaying pars, watches, and module-specific information
fragmentationPolicy.fragmentationThreshold	int	1500B
