Patent number: 10848976Abstract: The present invention involves a method for distributed dynamic spectrum allocation performed by a source device and the source device, a method for dynamic spectrum allocation performed by a power node and the power node, the method including sending to appropriate power nodes a query message indicating that the source device requests to find an idle licensed spectrum; receiving from the appropriate power nodes a query response message indicating licensed spectrums; and determining whether the licensed spectrums are idle and selecting an idle licensed spectrum from the licensed spectrums to be used. In this way, the provided method may implement distributed dynamic spectrum allocation without using a central authority.Type: GrantFiled: June 24, 2016Date of Patent: November 24, 2020Assignee: Nokia Technologies OyInventors: Jingyu Feng, Guangyue Lu

Publication number: 20180041526Abstract: Method and apparatus are disclosed for detecting mutual-aid collusive (MAC) attack in a voting action of an online voting system. According to some embodiments, the method comprises: calculating a consumer-voter (CV) matrix, and/or calculating a similarity (SIM) matrix; and determining MAC attackers in the voting action based at least in part on the calculated CV matrix and/or similarity matrix. The method may further comprise: extracting for each voter in the voting action, a CV vector from the CV matrix, and/or extracting for a consumer in the voting action, a CV vector from the CV matrix; judging whether there is only one CV vector having elements with a same CV value and/or whether the consumer's CV vector has elements with a same CV value; and in response to a positive judge result, determining that the voter corresponding to the only one CV vector or the consumer is a MAC attacker, and related voters corresponding to the elements with the same CV value are MAC attackers.Type: ApplicationFiled: March 6, 2015Publication date: February 8, 2018Inventors: Jingyu FENG, Guangyue LU, Honggang WANG

Publication number: 20150057041Abstract: A method includes performing blind spectrum sensing of a frequency band to determine whether a primary user is using the frequency band. The blind spectrum sensing is based at least in part on a comparison between a detection statistic based on a maximum correlation coefficient and a detection threshold based on theoretical computation of a distribution of the detection statistic. The maximum correlation coefficient is for correlations between a plurality of signals corresponding to a plurality of snapshots taken by a cognitive radio of the frequency band and corresponding to a plurality of antennas used by the cognitive radio for taking the snapshots. The method includes determining whether to communicate using the frequency band based on whether the blind spectrum sensing indicates the frequency band is or is not used by the primary user. Apparatus and program products are disclosed.Type: ApplicationFiled: August 22, 2013Publication date: February 26, 2015Applicant: Nokia CorporationInventors: Zhi Qiang Bao, Pei Zhao, Guangyue Lu
