Design and implementation of distributed dynamic spectrum allocation protocol
2014 IEEE International Conference on Communications Workshops (ICC), 2014In this paper, we design, implement, and evaluate a resource allocation protocol for distributed dynamic spectrum access (DSA). This protocol, based on learning techniques, enables users to locate and exploit unused spectrum opportunities effectively.

Spatio-Temporal Dynamic Spectrum Allocation with Interference Handling
2007 IEEE International Conference on Communications, 2007As for today, radio spectrum resource is rigidly partitioned for dedicated purposes. The exclusive license of fixed size spectrum blocks separated by guard bands easily solves the interference problems; however, the rigid allocation of spectrum is clearly inadequate for providing optimal spectrum efficiency for spatially and temporarily varying loads ...

Service provider competition and pricing for dynamic spectrum allocation
2009 International Conference on Game Theory for Networks, 2009We consider dynamic spectrum allocation in the downlink between multiple service providers and users, and develop a model that is applicable for many future scenarios. The service providers set prices for spectrum and transmit data to users, who purchase their spectrum.

Dynamic spectrum allocation in Femto based LTE network
2013 Fifth International Conference on Communication Systems and Networks (COMSNETS), 20133GPP has introduced LTE Femto cells to handle the traffic for indoor users and to reduce the load on the Macro cells. However, the current LTE Femto based system is not able to utilize the spectrum efficiently. Hence, we propose a new spectrum allocation method which dynamically allocates the spectrum between Macro and Femto cells and dynamically ...

Efficiency-Revenue Optimality Tradeoffs in Dynamic Spectrum Allocation
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010This paper proposes an auction mechanism for dynamic spectrum allocation that balances between two conflicting objectives: revenue and efficiency. The spectrum resources are allocated by FCC (i.e., the auctioneer) with the objective of maximizing revenue while also increasing efficiency or social welfare. Unfortunately, revenue and efficiency are often

Dynamic Spectrum Allocation Based on Interference Threshold Modeling
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010Dynamic transmission power based dynamic spectrum allocation (DSA) schemes are extensively adopted in cognitive ratio (CR) networks due to their flexible spectrum access strategies to improve spectrum utility. However such DSAs suffer from high sensitivity to the environment change.

Dynamic Spectrum Allocation in Mobile Communication
2015Das Spektrum eines Mobilfunkbetreibers wird derzeit statisch zugewiesen wobei hierfür die Regulierungsbehörde eine Auktion durchführt. Durch eine dynamische Allokation des Spektrums, wie beispielsweise in Cogentive Radio vorgeschlagen, kann der Datendurchsatz für Benutzer erhöht werden. In dieser Magisterarbeit wird eine neuartige Gleichung hergeleitet,

Profit Maximizing Pricing Strategies for Dynamic Spectrum Allocation
2007 41st Annual Conference on Information Sciences and Systems, 2007We consider a system where one service provider (SP) allocates spectrum to users subscribed to his network. The SP charges a two part tariff from the users comprising of a fixed subscription price and price per unit spectrum used. We formulate the spectrum allocation problem from the SP profit maximization framework and calculate the resulting ...

Dynamic Spectrum Allocation Strategies for Mobile Broadband Efficiency
Journal of Wireless Mobile Networks, Ubiquitous Computing, and Dependable ApplicationsSmartphones, tablets, and the endless appetite for video have stretched our wireless wave bands to their breaking point. Experts keep telling us we need a better way to squeeze those waves so everyone stays connected. Enter Dynamic Spectrum Allocation, or DSA-a glue-y term for letting devices grab empty channels on the fly instead of waiting in line ...
