BaseLayer (simple module)

Base module for all layer modules. Defines the in and out gates

Known subclasses:

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.
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		debug switch
headerLength	double		length of the MAC packet header (in bits)

Properties:

Name	Value	Description
class	BaseMacLayer

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
lowerControlOut	output	control to lower layer
