BasicMsduAggregationPolicy¶

Package: inet.linklayer.ieee80211.mac.aggregation

simple module BasicMsduAggregationPolicy

Implements a basic MSDU aggregation policy, controlled by parameters such as the minimum number of subframes needed to compose an A-MSDU, the minimum length for the aggregated payload, the maximum A-MSDU size, etc.

Inheritance diagram¶

Used in compound modules¶

Name	Type	Description
OriginatorQosMacDataService	compound module	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.

Extends¶

Name	Type	Description
SimpleModule	simple module	Base module for all INET simple 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
subframeNumThreshold	int	-1	Minimum number of subframes needed to compose an A-MSDU. (-1 means it won’t be checked)
aggregationLengthThreshold	int	-1	The minimum length for an aggregated payload necessary to create an A-MSDU (-1 means it won’t be checked).
maxAMsduSize	int	4065	-1 means infinity
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).
