16.5.3.2.1 Media Access Control. This sublayer, which depends on a physical layer, is a procedure controlled by the sender, in which several devices (on multidrop or bus networks) compete to gain access to the medium for data transfer. This sublayer decides, among competing devices, on who should gain the access to the media and send data.

It use MAC protocols to provides unique addressing identification and channel access control mechanism for network nodes to communicate with other nodes across a shared channel. 2012-07-06 1999-11-10 Medium Access Control Protocols Schedule-based: Establish transmission schedules statically or dynamically oTDMA oFDMA oCDMA Contention-based: oLet the stations contend for the channel oRandom access protocols Reservation-based: oReservations made during a contention phase oSize of packet in contention phase much smaller than a data packet What is Media Access Control (MAC) Layer? The MAC Layer is one of the two sublayers into which the data-link layer (layer 2) of the Open Systems Interconnection (OSI) reference model is subdivided based on the specifications of IEEE Project 802. The other sublayer is the logical link control (LLC) layer. 1997-10-15 Media Access Control security (MACsec) provides point-to-point security on Ethernet links.

Media Access Control layer (MAC layer): In the Open Systems Interconnection ( OSI ) model of communication, the Media Access Control layer is one of two sublayers of the Data Link Control layer and is concerned with sharing the physical connection to the network among several computers. Each computer has its own unique MAC address . Ethernet Media Access Control. Chapter 6. Ad Hoc and Sensor Networks – Roger Wattenhofer whether the medium is free terminals must not send if the medium is busy terminals can access the medium as soon as the busy tone stops the base station signals collisions and successful transmissions via the busy tone and acknowledgements, respectively (media access is not coordinated within this approach) Example: for CDPD Alternative Media Access Control Strategies Suppose you send a message to all the other 49 users saying, ‘I need the whole channel for about 1sec, do not use it, please’ As long as the overhead incurred in sending the message is less than 39 sec. the user will get better performance.
