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.

Medium Access Control (MAC) in Specification, LTE, MAC. MAC protocol layer exists in UE & eNodeb, It is part of LTE air interface control and user planes. MAC layer (Media Access Control layer) The part of the data link protocol that controls access to the physical transmission medium in local networks (see 802.3).The common MAC layer technologies are CSMA/CD for Ethernet and CSMA/CA for Wi-Fi. Medium Access Contro In most networks, multiple nodes share a communication medium for transmitting their data packets! The medium access control (MAC) protocol is primarily responsible for regulating access to the shared medium! The choice of MAC protocol has a direct bearing on the reliability and Media access control operates at layer 2 of the OSI model while Internet Protocol operates at layer 3. This allows MAC addressing to support networks other than TCP / IP. Manages the conversion between IP and Media Access Control addresses using the IP Network Address Resolution Protocol (ARP).
