MacProtocolBase

simple module

Module base for different MAC protocols.

Inheritance diagram

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

Known subclasses

Name	Type	Description
AckingMac	compound module	Implements a trivial MAC protocol for use in ~AckingWirelessInterface.
BMac	compound module	Implementation of B-MAC (also called 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.
EthernetCsmaMac	simple module	Implements the Ethernet CSMA/CD MAC protocol. It supports building both Ethernet CSMA/CD and Ethernet PLCA network interfaces.
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.
LMac	compound module	Implementation of L-MAC (Lightweight Medium Access Protocol for Wireless Sensor Networks).
ShortcutMac	simple 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.
