The impact of spectrum policies on the secondary spectrum market: A system dynamics approach

There has been a growing significance for Dynamic Spectrum Access (DSA) technology as a method to relieve the spectrum shortage problem and improve the efficiency of spectrum usage. For DSA technology to provide social and economic benefits, however, the dynamics of the secondary spectrum market must also co-evolve with the technology. Using the system dynamics (SD) methodology, we developed a secondary spectrum market model. The objective of this model is to integrate the SD approach, scenario and simulation analysis into a holistic dynamic consideration of the secondary spectrum market. Drawing on the model, we examined how the secondary spectrum market could evolve in the future and investigated how spectrum policies could influence spectrum utilization in the secondary spectrum market.
