Cooperative Spectrum Sensing Based on Dempter-Shafer Theory of Evidence in Cognitive Radio Network
Published 2013-08-01“…Cognitive radio has the advantage of high spectrum utilization since the spectrum can be shared by primary and secondary user.Meanwhile,the new adaptable characteristic is required for the secondary user.On the basis of analyzing D-S theory of evidence,a novel distributed cooperative spectrum sensing scheme was presented,which modified the combination equation for conflicting evidence source,and the BPA function based on fuzzy degree calculation was redefined.Simulation results show that the proposed scheme can sense the available spectrum in the cognitive radio networks very well,and can be used as a general spectrum sensing scheme in AWGN and Rayleigh fading channel when compared with the traditional "and","or" fusion rules and other D-S theory of evidence schemes in the previous literature.…”

Long Term Effects of Farming System on Soil Water Content and Dry Soil Layer in Deep Loess Profile of Loess Tableland in China
Published 2014-06-01“…Water stored in thick loessal soils is one of the most important resources regulating vegetation growth. However, soil water in the deep loess profile, which is critical for maintaining the function of the “soil water pool” is rarely studied because deep profile soil samples are difficult to collect. …”

Green communication and networking for Carbon-peaking and Carbon-neutrality: challenges and solutions
Published 2022-02-01“…Driven by the Carbon-peaking and Carbon-neutrality strategic goals, future mobile communication and networks need to drastically reduce energy consumption while satisfying the growing traffic demand.Therefore, it is necessary to study the theories and technologies used to send more information bits with less energy (SMILE).To meet the challenge, it was far from enough to rely solely on the improvements of wireless transmission technologies and hardware.It was necessary to explore efficient energy utilization mechanisms from the perspective of the system and network.Both energy saving and renewable energy utilization approaches were proposed, and solutions for the growing computing energy consumption were provided.Specifically, by introducing hyper-cellular network, agile coverage and elastic access were realized, and thus service base stations and edge servers could enter the sleeping mode to save energy when the traffic volume was low.Meanwhile, by the introduction of renewable energy and the smart adaption of energy flow and information flow, the energy consumption of the power grid could be greatly reduced.Furthermore, green computing and artificial intelligence could be realized through network function virtualization, energy-efficient coordination of communication and compute resources, and distributed computing and coordination approaches of moving agents.…”
