Abstract

This paper introduces a novel joint channel-aware and queuing-aware OFDMA scheduler for delay sensitive traffic based on a Hopfield Neural Network scheme. It allows providing an optimum OFDMA performance by solving a complex combinational problem. Some illustrative results on the dropping rate and delay have been obtained for a delay- sensitive service modelled as www traffic. These results, shown for comparison purposes, outperform significantly those obtained for a conventional heuristic scheduling.
