Abstract: With the development of signal processing technologies, full-duplex wireless transmission has attracted attention as a promising method to increase network throughput. In this study, we discuss a new Medium Access Control (MAC) protocol designed to improve throughput by inducing parallel transmissions by neighbours of an initial full-duplex transmitter (initiator). In our proposed approach, an initiator informs candidate terminals of an opportunity for parallel transmissions to avoid interference between transmissions. The results of computer simulations show that our proposal achieves up to maximum about 30% higher throughput than the traditional full-duplex communication. We also present to demonstrate that our proposed method may be expected to improve throughput performance effectively even under the network conditions that also involve traditional terminals performing half-duplex wireless communication.
