| Abstract |
This study focuses on addressing the communication protocols of the medium access control layer, known as MAC. Among the best-known protocols are the ALOHA protocols, in their pure and slotted version (S-ALOHA) and the carrier-sensing media access protocols known as CSMA (Carrier Sense Multiple Access) in its different versions; which have been the basis for the development of different communication standards. Currently, there are multiple versions of the classic protocols of this layer that have achieved and demonstrated an improvement to the performance presented in the base protocols, and new strategies are continuously proposed according to the technologies that emerge each year. In addition, its use continues to be valid for certain applications, being even necessary for the request of bandwidth channel resources for sending a high volume of information, as is the case of control channels and random access from cellular systems. © 2023 IEEE. |
