Spectrum aggregation based spectrum allocation for cognitive radio networks
2014 IEEE Wireless Communications and Networking Conference (WCNC), 2014In cognitive radio networks, the available spectrum holes are usually discontinuous. Hence, it is hard to exploit these spectrum holes because the bandwidth of an individual one may not be able to satisfy the wide bandwidth requirement imposed by secondary users (SUs).

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 ...

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.

Ensuring Minimum Spectrum Requirement in Matching-Based Spectrum Allocation
IEEE Transactions on Mobile Computing, 2018To enable dynamic spectrum access, service providers with spare spectrum (sellers) trade with those who are in need of additional spectrum (buyers). In a spectrum market, the transaction result is essentially a matching between sellers and buyers. Though it is tempting to optimize the matching over certain utility functions, a stable matching is more ...

Allocation of licensed and unlicensed spectrum in heterogeneous networks
2016 Australian Communications Theory Workshop (AusCTW), 2016In order to support fast growing mobile data traffic, wireless operators have started to use multiple radio access technologies (RATs) over multiple licensed and unlicensed frequency bands. A widely used method is WiFi off-loading of cellular network traffic. A recent proposal is side-by-side deployment of Long Term Evolution (LTE) in licensed spectrum

Link capacity allocation by input power spectrum
Telecommunication Systems, 1994Consider a multimedia input traffic stream, described by a stationary random process. Our previous study indicates that second-order input statistics, which are described by a power spectrum in the frequency domain, play a dominant role in queueing performance as compared with higher-order input statistics. In this paper, we show the significant effect
