Recent advances in the physical layer technologies such as MU-MIMO, CDMA, OFDMA, allows simultaneous reception of multiple packets by a node. This promising technology is called the Multi-Packet Reception (MPR). The medium access control (MAC) protocol for the next generation wireless networks have to leverage the MPR capability offered by the Physical layer, else they will underperform and will bring down the overall performance of the wireless networks. In this talk we will concentrate on the design and performance evaluation of the MAC protocols for supporting the MPR. Starting from Aloha, CSMA, DFSA, etc,we will show MPR MAC protocols can be designed all the way leading to the adaptation of IEEE 802.11 standard MAC protocols including the latest IEEE 802.11ax.
