Dynamic Spectrum Allocation for Uplink Users With Heterogeneous Utilities
IEEE Transactions on Wireless Communications, 2009Dynamic allocation of spectrum prior to transmission is an important feature for next generation wireless networks. In this work, we develop and analyze a model for dynamic spectrum allocation, that is applicable for a broad class of practical systems.

A Highly Available Spectrum Allocation Service Model in Dynamic Spectrum Market
Future Generation Computer Systems, 2012Dynamic spectrum access and adaptive spectrum allocation can significantly improve the resource utilization in dynamic spectrum market. To achieve this, it is important to stimulate the primary license holders to open up their under-utilized spectrum for sharing and adaptive allocation so as to maximize the secondary user's transmission reliability ...

Dynamic Spectrum Allocation in Composite Reconfigurable Wireless Networks
IEEE Communications Magazine, 2004Future wireless systems are expected to be characterized by increasing convergence between networks and further development of reconfigurable radio systems. In parallel with this, demand for radio spectrum from these systems will increase, as users take advantage of high quality multimedia services.

Tabu Search for Dynamic Spectrum Allocation in Cellular Networks
Transactions on Emerging Telecommunications Technologies, 2012ABSTRACTIn this paper, we present and analyse a Tabu Search algorithm for Dynamic Spectrum Allocation in cellular networks. We study a case where an operator is providing packet services to the end users. The objective of the cellular operator is to maximise its reward while taking into account the trade‐off between the spectrum cost and the revenues ...

Primary-Prioritized Markov Approach for Dynamic Spectrum Allocation
IEEE Transactions on Wireless Communications, 2009Dynamic spectrum access has become a promising approach to fully utilize the scarce spectrum resources. In a dynamically changing spectrum environment, it is very important to consider the statistics of different users' spectrum access so as to achieve more efficient spectrum allocation.

An Optimal Spectrum Allocation Strategy for Dynamic Spectrum Markets
2019 International Conference on Wireless and Mobile Computing, Networking and Communications (WiMob), 2019Dynamic spectrum markets for future wireless network devices will involve complex spectrum transactions. The spatio-temporal spectrum availability and the existence in the market of many diverse players with different power limit and channel bandwidth requirements, calls for new ways of allocating the spectrum [1].

Dynamic Spectrum Allocation by 5G Base Station
2020 International Wireless Communications and Mobile Computing (IWCMC), 2020In 5G era, the base stations are capable of providing multiple services in various scenarios (e.g. vehicle network, Internet of Things), which provides fine opportunity to enhance spectrum efficiency. Base stations can flexibly utilize the idle frequency band for spatiotemporal low-demand services and guarantee services with high priority (e.g.

Dynamic Spectrum Allocation Scheme for Heterogeneous Network
Wireless Personal Communications, 2016Recently, femtocells (HeNBs) are deployed in heterogeneous network (HetNets) attributable to the addition of coverage, capacity and impeccable spectrum efficiency in private buildings/office complexes surroundings. This unplanned placement of HeNBs creates co-channel interference (CCI) in orthogonal frequency division multiple access (OFDMA).
