    Spectrum sensing method based on residual dense network by Jianxin GAI, Xianfeng XUE, Ruixiang NAN, Jingyi WU

    Published 2021-12-01
    “…Aiming at the problem that the traditional spectrum sensing method based on convolutional neural network(CNN) did not make full use of image feature and the ability of extracting the image feature was limited by the shallow network structure, a spectrum sensing method based on the residual dense network (ResDenNet) was proposed.By adding dense connections in the traditional neural network, the information reuse of the image feature was achieved.Meanwhile, shortcut connections were employed at both ends of the dense unit to implement deeper network training.The spectrum sensing problem was transformed into the image binary classification problem.Firstly, the received signals were integrated into a matrix, which was normalized and transformed by gray level.The obtained gray level images were used as the input of the network.Then, the network was trained through dense learning and residual learning.Finally, the online data was input into the ResDenNet and spectrum sensing was implemented based on image classification.The numerical experiments show that the proposed method is superior to the traditional ones in terms of performance.When the SNR is as low as -19 dB, the detection probability of the proposed method is still high up to 0.96 with a low false alarm probability of 0.1, while a better generalization ability is displayed.…”

    Reliability modeling and planning of energy harvesting based on uncertainty theory by Zhe WANG, Taoshen LI, Jin YE, Zhihui GE, Min WU

    Published 2018-05-01
    “…Energy harvesting network is a new form of computer networks.It can convert the environmental energy into usable electric energy,and supply the electrical energy as a primary or secondary power source to the electronic device for network communication.However,the energy harvesting process has great volatility and uncertainty,the traditional analytical method based on probability distribution function to describe the energy collection process can not accurately simulate the actual situation,resulting in higher depletion probability of nodes,then the reliability cannot be guaranteed as a result.For this,the energy harvesting reliability of energy harvesting nodes was defined,represented with the degree of normal operation,respectively set up the node reliability models with no battery and infinite battery.As an example for maximum node achievable rate,the uncertain multilevel programming model based on node reliability was put forward,then the network efficiency was improved under the premise of ensuring node reliability.An energy average allocation (EAA) algorithm was proposed and the upper bound of competitive ratio of the algorithm was proved theoretically.Finally,the actual wind power data was taken as an example to verify the feasibility and effectiveness of the proposed model and method.…”
