Extends:

Name	Type	Description
BaseLayer	simple module	Base module for all layer modules. Defines the in and out gates

Known subclasses:

Name	Type	Description
BMacLayer	simple module	Implementation of B-MAC (called also Berkeley MAC, Low Power Listening or LPL). See C++ documentation for details.
csma	simple module	Generic CSMA protocol supporting Mac-ACKs as well as constant, linear or exponential backoff times.
CSMAMacLayer	simple module	CSMA MAC protocol
LMacLayer	simple module	Implementation of L-MAC (Lightweight Medium Access Protocol for Wireless Sensor Networks)
Mac80211	simple module	Implementation of the 802.11b MAC protocol. This module is intended to be used in combination with the Decider80211 as decider for the physical layer.
SimpleMacLayer	simple module	(no description)
UWBIRMac	simple module	This class provides helper function for MAC modules that use the UWB-IR IEEE 802.15.4A model. Just before sending down a packet to the UWBIRPhyLayer, call prepareData(UWBIRMacPkt* packet). Just after receiving a packet from the UWBIRPhyLayer, call validatePacket(UWBIRMacPkt* packet) and check the returned bool value to know if the packet could be decoded successfully.

Parameters:

Name	Type	Default value	Description
notAffectedByHostState	bool	false
coreDebug	bool	false	debug switch
headerLength	int		length of the MAC packet header (in bits)
address	string	"auto"	MAC address as hex string (12 hex digits), or "auto". "auto" values will be replaced by a generated MAC address in init stage 1.

Properties:

Name	Value	Description
class	BaseMacLayer

Gates:

Name	Direction	Description
upperLayerIn	input	from upper layer
upperLayerOut	output	to uppe layer
upperControlIn	input	control from upper layer
upperControlOut	output	control to upper layer
lowerLayerIn	input	from lower layer
lowerLayerOut	output	to lower layer
lowerControlIn	input	control from lower layer
lowerControlOut	output	control to lower layer
