An Efficient Tabu Search DSA Algorithm for Heterogeneous Traffic in Cellular Networks
In this paper, the authors propose and analyze a TS (Tabu Search) algorithm for DSA (Dynamic Spectrum Access) in cellular networks. They consider a scenario where cellular operators share a common access band, and they focus on the strategy of one operator providing packet services to the end-users. The authors consider a soft interference requirement for the algorithm's design that suits the packet traffic context. The operator's objective is to maximize its reward while taking into account the trade-off between the spectrum cost and the revenues obtained from end-users.
