Multiple Access with Collision Avoidance for Wireless (MACAW) [1] is a slotted medium access control (MAC) protocol widely used in ad hoc networks. [2] Furthermore, it is the foundation of many other MAC protocols used in wireless sensor networks (WSN). [2] The IEEE 802.11 RTS/CTS mechanism is adopted from this protocol.
Multiple access with collision avoidance (MACA) is a slotted media access control protocol used in wireless LAN data transmission to avoid collisions caused by the hidden station problem and to simplify exposed station problem.
Waitzman described an improvement of his protocol in RFC 2549, IP over Avian Carriers with Quality of Service (1 April 1999). Later, in RFC 6214 —released on 1 April 2011, and 13 years after the introduction of IPv6 — Brian Carpenter and Robert Hinden published Adaptation of RFC 1149 for IPv6 .

A channel access method may also be a part of the multiple access protocol and control mechanism, also known as medium access control (MAC). Medium access control deals with issues such as addressing, assigning multiplex channels to different users and avoiding collisions.
Macaws also mimic sounds, and while they don't talk as much as some parrots do, they can learn words and phrases. But there is something that all parrots love, and that's music.

The air interface of a cellular network is at layers 1 and 2 of the OSI model; at layer 2, it is divided into multiple protocol layers. In UMTS and LTE, those protocols are the Packet Data Convergence Protocol (PDCP), the Radio Link Control (RLC) protocol, and the MAC protocol. The base station has absolute control over the air interface and ...
