A framework for multiple access protocols supporting the admission and sustenance of concurrent transmissions in Gaussian interference channels (G-IC) encountered in opportunistic unstructured networks or unused spectral bands under quasistatic fading is proposed. Each node is assumed to be equipped with successive decoding capabilities and seeks admission to the network by requesting a minimum rate, stipulating its maximum tolerable probability of information-theoretic outage, and specifying its energy budget. Admission rules are proposed for both the high and low signal to interference-plus-noise ratio (SINR) regimes. These decision rules are based on the ability of the existing nodes in the network to maintain their performance levels and satisfy their own constraints subsequent to potentially admitting the new transmit-receive node pair. Significant increases in admission rates are observed over conventional multiple access strategies across the range of SINRs encountered in practice.
