IMacProtocol

module interface

This interface provides an abstraction for different MAC protocols.

Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Implemented by

Name	Type	Description
AckingMac	compound module	This module implements a trivial MAC protocol for use in AckingWirelessInterface.
BMac	compound module	Implementation of B-MAC (called also Berkeley MAC, Low Power Listening or LPL). See C++ documentation for details.
CsmaCaMac	compound module	Implements an imaginary CSMA/CA-based MAC protocol with optional acknowledgements and a retry mechanism. With the appropriate settings, it can approximate basic 802.11b ad-hoc mode operation.
Ieee80211Mac	compound module	Implementation of the 802.11 MAC protocol. This module is intended to be used in combination with the Ieee80211Radio module as the physical layer.
Ieee802154Mac	compound module	Generic CSMA protocol supporting Mac-ACKs as well as constant, linear or exponential backoff times.
Ieee802154NarrowbandMac	compound module	(no description)
LMac	compound module	Implementation of L-MAC (Lightweight Medium Access Protocol for Wireless Sensor Networks).
ShortcutMac	simple module	This module implements a simple shortcut to peer MAC protocol that completely bypasses the physical layer. Packets received from the upper layer protocols are never lost. The MAC protocol directly sends packets to the destination MAC protocol without any physical layer processing. Physical layer overhead is simply simulated by overhead bits, overhead transmission duration and a propagation delay.
XMac	compound module	Implementation of X-MAC. See C++ documentation for details.

Used in compound modules

Name	Type	Description
WirelessInterface	compound module	This module implements a generic wireless network interface.

Known subclasses

Name	Type	Description
IIeee80211Mac	module interface	Module interface for the IEEE 802.11 MAC module type.
