A Spectrum Pooling-based Algorithm in Spectrum Aggregation and Allocation

摘要：

　　Most of existing spectrum allocation algorithms for cognitive radio network are based on continuous spectrum assignment and the user demands are not considered.For this reason,many small spectrum fragments that are smaller than the user demands are generated and these spectrum fragments cant be fully utilized which make a wasteful use of spectrum resources.A new spectrum aggregation and allocation algorithm based on spectrum pooling is proposed in this paper.The discontinuous small spectrum fragments could be aggregated to meet the user demands as much as possible to enhance the spectrum efficiency by using the new algorithm.
