Abstract
B3G wireless networks are expected to be characterized by the pouring of different radio access technologies (RAT) and diversified service requirements. In parallel with this, the irreconcilable conflicts between the great demand for radio spectrum and its scarcity bring the issues of dynamic spectrum management (DSM) and efficiency in spectrum utilization into our sight. This article aims to investigate the possibilities of a novel DSM scheme with the help of game theory in microeconomics. In the context of distributed reconfigurable networks in the charge of one operator, we propose market competition based dynamic spectrum management (MCDSM) schemes based on multi-agent models. The competition mechanism, related technologies and proposed algorithm are also described in details. The study reveals that MCDSM scheme utilizes the spectrum efficiently, enhances the fairness among different radio access networks (RAN) and maximizes the operator's profits.
