Evaluating secondary transmission opportunities with full duplex radios

A basic property of wireless networks is the half duplex nature of their links. However, previous works have already shown, with real prototypes of full duplex radios, to be possible for a node to transmit and receive packets at the same time. Nevertheless, the gains that result from such techniques are not straightforward. In this work we analyze how frequently full duplex transmissions can occur in typical wireless network scenarios. Simulations were conducted in both infra-structured and multihop networks with several traffic patterns, and results show potential gains up to 99.96% and 36.93% in the infra-structured and multihop cases, respectively.
