Example Improvements of Dynamic Spectrum Management ( 089 )
This information-only contribution defines some potential dynamic spectrum-management methods and provides examples of potential improvements in their use. This contribution is not meant to provide sample text or methods for dynamic spectrum management, but rather to motivate study. This contribution investigates two types of spectrum management: static and dynamic. Dynamic spectrum management ...
متن کاملA Survey on Dynamic Spectrum Access via Cognitive Radio: Taxonomy, Requirements, and Benefits
Conventionally, interference protection among radio spectrum users is guaranteed through a policy of spectrum licensing that provides exclusive access to licensed users. However, as it is becoming extremely difficult to satisfy the growing demand for radio spectrum with this conventional policy, a flexible policy that can improve radio spectrum access and utilization without causing interferenc...
متن کاملPaper Title (use style: paper title)
This paper presents a new approach for dynamic spectrum management for heterogeneous wireless devices. Local congestion degrades the reliability of wireless applications in the License Exempt bands. This leads to the research questions: (1) how to realize equal spectrum sharing between dissimilar systems, and (2) how to improve the collective spectrum efficiency. A solution is in dynamic distri...
متن کاملDynamic Spectrum Management Methodology for WCDMA Systems Based on Inter-Cell Interaction Approach
Classical spectrum planning exercise is based on some expected spatial traffic distributions and corresponding load levels. Nevertheless, practical network deployments show that the dynamism in mobile scenarios and unpredictable changes in traffic distribution make traffic estimation severely frail. Hence, new approaches should be developed to detect the relevant changes in traffic distribution...
متن کاملPotential Game for Dynamic Spectrum Management in Cognitive Radio Networks
Dynamic spectrum management is one of the key technologies in cognitive radio networks, and more and more researchers have been paying much attention to algorithms and models for Spectrum sharing. In this paper, we present a dynamic spectrum management application model based on potential game. Firstly, the mapping relationship is constructed for sections in cognitive radio network and game the...
متن کاملAuction-driven Market Mechanisms for Dynamic Spectrum Management
There is nowadays unanimous agreement that spectrum should be allocated in a dynamic fashion so as to match the stochastic supply and demand by responding to spatiotemporal variations of spectrum availability and request. The imminent liberalization of the spectrum markets is expected to provide more control mechanisms for spectrum exploitation in that respect. Wireless network entities will be...
