A Novel Bargaining Based Dynamic Spectrum Management Scheme in Reconfigurable Systems

B3G wireless networks are expected to be characterized by the pouring of diversified services supported by different operators. In parallel with this, how to efficiently utilize the limited radio spectrum and guarantee the operator¿s profits has become a joint economical and technical problem. As a possible solution, in this paper, we set forth a novel bargaining approach for dynamic spectrum management (DSM) based on alternating-offer bargaining games in microeconomics. In the context of distributed reconfigurable networks in the charge of different operators, bargaining based dynamic spectrum management (BDSM) scheme introduces trading agent (TA), changing bargaining ability as well as revenue-sharing mechanism to facilitate the spectrum trading. Related technologies, bargaining games and proposed algorithm are also described in details. Simulation results show that with imperfect load predicting, BDSM is effective in improving the utilization of spectrum, expanding the individual operator¿s profits and enhancing the fairness among different RANs (radio access networks).
