An OFDMA-based Hybrid MAC Protocol for IEEE 802.11ax [PDF]
Infocommunications journal, 2019 Two types of MAC mechanisms i.e., random access and reservation could be adopted for OFDMA-based wireless LANs. Reservation-based MAC is more appropriate than random access MAC for connection-oriented applications as connectionoriented applications provide strict requirements of traffic demands. On the other hand, random access mechanism is a preferred
