Potential Cognitive Radio Denial-of-Service Vulnerabilities and Protection Countermeasures: A Multi-Dimensional Analysis and Assessment
White Paper Cognitive radios sense spectrum activity and apply spectrum policies in order to make decisions on when and in what bands they may communicate. An analysis of how vulnerable are victim... [20 Jun 2009]
Potential Cognitive Radio Denial of Service Attacks and Remedies
White Paper Cognitive radios sense spectrum activity and apply spectrum policies in order to make decisions on when and in what bands they may communicate. The goal is to assist... [20 Jun 2009]
Peter Cochrane's Blog: We have plenty of radio spectrum
Comment But in the back of my mind I have the recollection of being on the periphery of a spectrum study of Chicago by the Illinois Institute of Technology some 15 or so years ago that revealed a total spectrum... [09 Jun 2009]
A Framework for Cognitive WiMAX With Frequency Agility
White Paper Cognitive radios have the ability to sense the radio spectrum environment and to switch dynamically to available frequency ranges. In the proposed cognitive WiMAX architecture, base... [22 Apr 2009]
Ultra Wide Bandwidth Communications Towards Cognitive Radio
White Paper Cognitive Radio (CR) is an emerging approach for a more flexible usage of the precious radio spectrum resources. Finally, it shows the great potential of the UWB technology in adapting the transmitted... [11 Jul 2008]
Coexistence Issues in Cognitive Radios Based on Ultra-Wide Bandwidth Systems
White Paper Then, based on this methodology the paper shows the great potential of the UWB technology in adapting the transmitted spectrum to counteract NB interference and at the same time to guarantee low spectral emissions over... [11 Jul 2008]
Distributed Load Balancing Algorithm for Adaptive Channel Allocation for Cognitive Radios
White Paper The growing interest in the cognitive radio technology and its capability to offer more efficient spectrum usage brought this problem back as one of the most popular research topics nowadays. This paper... [10 Jul 2008]
Peter Cochrane's Blog: Wireless jelly
Comment The good news is that it can only all get better as we migrate further up the spectrum from 2.4GHz and 5GHz toward 60GHz and higher. But I suspect that future cognitive radios will almost single-handedly... [13 Jun 2008]
Game-Theoretic Distributed Spectrum Sharing for Wireless Cognitive Networks With Heterogeneous QoS
White Paper Ubiquitous wireless networking calls for efficient Dynamic Spectrum Allocation (DSA) among heterogeneous users with diverse transmission types and bandwidth demands. To meet user-specific Quality-of-Service (QoS)... [23 Aug 2007]
Spectrum Shaping for Interference Management in Cognitive Radio Networks
White Paper Most dynamic spectrum access research centers on determining the set of frequencies being used by spectrum license holders, taking its converse, and from what remains selecting the optimal subset of... [13 Apr 2007]
Adaptive OFDM System Design for Cognitive Radio
White Paper Recently, Cognitive Radio has been proposed as a promising technology to improve spectrum utilization. A highly flexible OFDM system is considered to be a good candidate for the... [11 Apr 2007]
Wideband Spectrum Probe for Distributed Measurements in Cellular Band
White Paper This paper presents the architecture of a sensing probe for wideband measurement and distributed measurement method to measure, characterize and model the utilization of the spectrum. The paper presents the sample... [07 Dec 2006]
US Election 2004: Bush and Kerry hold forth on tech issues
News Bush and Kerry, both looking to gain an edge in what might be an extremely close race, expressed their views on 12 topics, which also included spam, privacy and unlicensed wireless spectrum. The candidates were also... [22 Oct 2004]
