We present the Concurrent Transmission or Reception Multiple Access (CTRMA) protocol as an example of embracing interference in wireless ad hoc networks, even when each node is endowed with a single half-duplex radio and a single antenna. CTRMA uses OFDMA to enable each node to either send or receive multiple concurrent transmissions over orthogonal subchannels (groupings of subcarriers). With CTRMA, a node transmits multiple transmissions at the same time by negotiating the subchannels over which transmissions take place by using information attained with a channel priority assignment algorithm. CTRMA supports dynamic bandwidth selection and enhances channel reuse. We prove the correctness of CTRMA and use simulation experiments to illustrate the major performance advantages of CTRMA over prior channel access protocols proposed for single-radio single-channel, single-radio multi-channel and multi-radio multi-channel wireless ad hoc networks.
