BaseMacLayer (simple module)

Base module for every mac layer module

Used in compound modules:

If a module type shows up more than once, that means it has been defined in more than one NED file.

NicLMAC (compound module)

This module implements a LMAC network interface card using the "LMacLayer" MAC layer module

Parameters:

Name	Type	Default value	Description
notAffectedByHostState	bool	false
coreDebug	bool		debug switch
headerLength	double		length of the MAC packet header (in bits)
debug	bool	false	enable per module debug
slotDuration	double	100ms	how long is a slot?
queueLength	double	10	length of MAC header
defaultChannel	double	0	default channel
bitrate	double	19200bps	bit rate
reservedMobileSlots	int	2
numSlots	int	64
txPower	double	50

Properties:

Name	Value	Description
class	LMacLayer

Gates:

Name	Direction	Description
upperGateIn	input	from upper layer
upperGateOut	output	to uppe layer
upperControlIn	input	control from upper layer
upperControlOut	output	control to upper layer
lowerGateIn	input	from lower layer
lowerGateOut	output	to lower layer
lowerControlIn	input	control from lower layer
