Abstract

This paper introduces a novel algorithm modification for the conventional game theory-based time slot assignment method applied to the Digital Video Broadcast Return Channel via Satellite (DVB-RCS) system. The procedure considers the spectral efficiency as a weighting parameter for the resulting convex optimization problem of the Nash Bargaining Solution. This approach guarantees the fulfillment of Quality of Service (QoS) constraints while maintaining a higher fairness measure; results show a 5% improvement in fairness, with a 73% decrease in the standard deviation between frames, also managing to reach a 12.5% increase in individual terminal capacity distribution satisfaction.
