Description: Cognitive radios sense spectrum activity and apply
spectrum policies in order to make decisions on when and in what
bands they may communicate. These activities go beyond what is
done when traditional radios communicate. This paper examines
the denial of service vulnerabilities that are opened by these
additional activities and explores potential protection remedies
that can be applied. An analysis of how vulnerable are victim
cognitive radios to potential denial of service attacks is presented
along different axis, namely the network architecture employed,
the spectrum access technique used and the spectrum awareness
model. The goal is to assist cognitive radio designers to incorporate
effective security measures now in the early stages of cognitive
radio developmen. Platform: |

Description: 文章讲述了现在韩国的频谱政策和动态频谱接入技术。过去韩国的频谱管理政策需要特权，并且只有一小部分频谱可以公用。随着无线技术的发展，现在，韩国政府，使用了机遇动态频谱接入的新型频谱策略，例如LBT技术用于REID，UWB和FACS等。MIC还考虑如何在DTV过渡完成后，重新分配频谱。新型的无线电技术如认知无线电和SDR将在UHF边带中应用新的服务。MIC试图用一用有效地方式开放频谱并接受新技术用于频谱策略中。-In this paper, we introduce spectrum policies and
dynamic spectrum access technologies in Korea. In the past,
Korea spectrum management was the command and control with
exclusive usage rights and small portions of spectrum commons
bands. With the development of the radio technologies, Recently,
Korea government, MIC(ministry of information and com-
munication), has been adopting new spectrum policies based on
dynamic spectrum access technology such as LBT(Listen Before
Talk) for RFID, UWB, and FACS(Flexible Access Common
Spectrum) etc. MIC is also considering spectrum reallocation of
digital dividend bands after DTV transition. New radio
techniques such as cognitive radio and SDR will be applied to
new services in this UHF band. MIC is trying to open the radio
spectrum in an efficient way and adopt new technology into
spectrum policy. Thus MIC is extending the open spectrum such
as spectrum commons and spectrum liberalization bands. Platform: |

Description: 认知无线电中频谱共享的方法。是基于动态频谱租用的，运用了博弈论的原理。-Hierarchical dynamic spectrum access (DSA) has
received the most attention in recent years as the solution for
better spectrum utilization. In this paper, on the other hand,
we develop a framework for dynamic spectrum leasing (DSL).
Power control in hierarchical DSA networks only involves that of
controlling secondary user transmissions. Thus, in game theoretic
formulations of power control in cognitive DSA networks only
secondary users are considered as players of the game. In
proposed dynamic spectrum leasing, on the other hand, the
primary users are rewarded for allowing secondary users to
operate in their licensed spectrum. Thus, in the proposed DSL
networks the primary users have an incentive to allow secondary
users to access the spectrum whenever possible to the maximum
extent. We develop a game theoretic framework for such dynamic
spectrum leasing in which primary users actively participate in
a non-cooperative game with secondary users by selecting an
interfere Platform: |

Description: 经典的频谱共享的EI检索算法，运用动态频谱租用来提高频谱利用率。-Dynamic Spectrum Leasing (DSL) is a new
paradigm for efficient spectrum sharing in cognitive radio
networks that was recently proposed in [1]–[3]. Unlike in a
hierarchical dynamic spectrum access (DSA) network, DSL
allows active participation of both the primary and the secondary
users in the spectrum sharing process. In this paper we further
generalize the DSL game introduced in [2] by allowing for linear
multiuser detectors, in particular the matched filter (MF) and
linear minimum mean squared error (LMMSE) receivers, at the
secondary base stations. We establish the conditions so that the
DSL game has desired equilibrium properties. Performance of
the proposed system at the equilibrium is compared through
simulations Platform: |
