Demand-Driven Dynamic Spectrum Allocation in Heterogeneous Cellular Networks
In this paper, we address the dynamic spectrum allocation problem in next generation cellular networks under the coordinated dynamic spectrum access (CDSA) model. Firstly, considering spectrum demands of base stations, we formulate spectrum allocation under physical interference models as a nonlinear optimization problem. Then, we propose a demand-driven dynamic spectrum allocation algorithm by...
متن کاملPerformance Analysis of Dynamic Spectrum Allocation in Heterogeneous Wireless Networks
© 2010 ETRI Journal, Volume 32, Number 2, April 2010 Increasing convergence among heterogeneous radio networks is expected to be a key feature of future ubiquitous services. The convergence of radio networks in combination with dynamic spectrum allocation (DSA) could be a beneficial means to solve the growing demand for radio spectrum. DSA might enhance the spectrum utilization of involved radi...
متن کاملTabu Search for Dynamic Spectrum Allocation (DSA) in Cellular Networks†
In this paper, we present and analyze a Tabu Search (TS) algorithm for Dynamic Spectrum Allocation (DSA) in cellular networks. We study a case where an operator is providing packet services to the endusers. The objective of the cellular operator is to maximize its reward while taking into account the trade-off between the spectrum cost and the revenues obtained from end-users. These revenues ar...
