Dynamic Spectrum Allocation by Hierarchical Resource Trading
VTC Spring 2008 - IEEE Vehicular Technology Conference, 2008Dynamic spectrum allocation is a key technique to face spectrum scarcity and inefficient pre-allocation of resources in an environment of rapidly growing demands for mobile communications. By allowing operators to adaptively exchange transmission resources of their communication systems with each other by way of trading, short-term traffic variations ...

DSASim: A Simulation Framework for Dynamic Spectrum Allocation
2007 IEEE Wireless Communications and Networking Conference, 2007The current methodology for distributing the frequency spectrum among users is in need of revamping. This is necessary in order to increase the number of users able to access the communication channels; to better manage usage in metropolitan areas, where the usage of wireless communication is still rapidly increasing; and to ensure adequate frequency ...

Spectrum allocation and scheduling in dynamic spectrum access wireless networks
The Fourth International Conference on Heterogeneous Networking for Quality, Reliability, Security and Robustness & Workshops, 2007In this paper, we study the joint spectrum allocation and scheduling problems with the objectives of maximizing through-put and achieving certain fairness in Dynamic Spectrum Access (DSA) wireless networks. A novel Multi-Channel Contention Graph (MCCG) is proposed to characterize the impact of interference under the protocol interference model.

Joint Dynamics of Spectrum Allocation and User Behavior in Spectrum Markets
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009Adaptive radio resource management policy aware of the demand for wireless services is termed dynamic spectrum access (DSA). In order to evaluate the effectiveness of DSA, dynamics of the demand should be considered. In the present paper, dynamics of the spectrum market, which is a way to realize DSA, are evaluated from the economic perspective ...

Dynamic Spectrum Allocation Algorithms
2000Abstract : In our previous funding, we reported the following. The standard online scheduling method to avoid fragmentation is called First Fit, which roughly speaking tries to schedule every task as early in time and as low in the spectrum as possible.

Dynamic spectrum allocation based on GA
2008 International Workshop on Metamaterials, 2008According to some specific spectrum rules, this paper represents two kinds of bandwidth scale: relative scale and absolute scale. Genetic algorithm with decimal encoding is applied to analyze and estimate the feasibility of dynamic spectrum allocation.

A metaheuristic based fair dynamic spectrum allocation policy
2011 Fifth IEEE International Conference on Advanced Telecommunication Systems and Networks (ANTS), 2011This work proposes a novel dynamic and adaptive yet fair spectrum allocation policy to be adopted by a service provider (SP). Here, we consider a scenario where a single SP owns multiple access networks (ANs) of different (not necessarily competing) technologies.

Dynamic spectrum allocation for heterogeneous cognitive radio network
2016 IEEE Wireless Communications and Networking Conference, 2016One important issue associated with spectrum management in heterogeneous cognitive radio network is: how to appropriately allocate the spectrum to the secondary senderdestination (S-D) pair for sensing and utilization. In this work, the authors investigate the spectrum allocation problem under a more practical scenario, taking the heterogeneous ...

Dynamic spectrum allocation in cognitive radio: Throughput calculations
2016 IEEE International Black Sea Conference on Communications and Networking (BlackSeaCom), 2016In this paper, we use queuing theory (egalitarian process sharing) to derive throughput expressions for dynamic spectrum allocation in cognitive radio systems. In particular, we consider different priority groups, for example, secondary users who can access the channel only if no primary user is active.

General distributed economic framework for dynamic spectrum allocation
Computer Communications, 2009The emergence of novel radio techniques enables the application of advantageous revolutionary spectrum policies. An important body of research has appeared about possible frequency management schemes, but none of them proposes solutions that meet every related criteria.
