Future Research Directions

Abstract

While there is still need for better spectrum auction mechanisms that can efficiently increase spectrum utilization and maintain nice economic properties, researchers start to pay attention other problems in auction, such as collusion. Although the collusion problem has been studied for homogeneous static spectrum auction, it is not sure whether dynamic spectrum auction and spectrum heterogeneity will raise new challenges, and how to deal with such challenges remains an open issue. In this chapter, we will discuss some possible research directions in the future.
