Abstract: Systems and methods are described for point-to-point and point-to-multipoint full duplex networking. In some embodiments, physical, medium access control (MAC), and routing protocols are integrated. In some embodiments, cross-layer optimization by the use of a full duplex capability table in performing routing and messaging is used to increase the channel utilization of full duplex networks, thereby making it possible for multiple nodes to communicate simultaneously over the same channel. In some embodiments, such full duplex capability is provided using Wi-Fi or Wi-Fi-like wireless protocols in a mesh network.
