    A spatial diversity cooperative spectrum sensing system based on blockchain and deep learning by Zhongshan XIAO, Chunqi WANG, Daquan FENG

    Published 2023-10-01
    “…Cooperative spectrum sensing is a key technology in cognitive radio.A data-driven intelligent cooperative spectrum sensing system was proposed with spatial diversity running on a smart contract to address issues of security, privacy, incentive and hidden terminals in cooperative spectrum sensing.Specifically, a motivated spectrum sensing system was designed by taking advantage of the decentralization of blockchain technology and the immutability of data.Secondly, a deep learning-based approach was proposed to identify malicious users in the system.In addition, to achieve higher accuracy in recruiting sensing nodes more efficiently in the system, a hard decision cooperative spectrum sensing fusion algorithm based on performance weights and spatial diversity was designed.The experimental results indicate that the proposed solution outperforms traditional cooperative spectrum sensing algorithms in terms of security, privacy, motivation, and sensing accuracy.…”

    Multi-channel based edge-learning graph convolutional network by Shuai YANG, Ruiqin WANG, Hui MA

    Published 2022-09-01
    “…Usually the edges of the graph contain important information of the graph.However, most of deep learning models for graph learning, such as graph convolutional network (GCN) and graph attention network (GAT), do not fully utilize the characteristics of multi-dimensional edge features.Another problem is that there may be noise in the graph that affects the performance of graph learning.Multilayer perceptron (MLP) was used to denoise and optimize the graph data, and a multi-channel learning edge feature method was introduced on the basis of GCN.The multi-dimensional edge attributes of the graph were encoded, and the attributes contained in the original graph were modeled as multi-channel.Each channel corresponds to an edge feature attribute to constrain the training of graph nodes, which allows the algorithm to learn multi-dimensional edge features in the graph more reasonably.Experiments based on Cora, Tox21, Freesolv and other datasets had proved the effectiveness of denoising methods and multi-channel methods.…”

    Power control strategy with joint of multi-packet reception and fuzzy logic control by Jiang-hong HAN, Song-hua HU, Bin LIU, Zhen CHEN, Lei LIU

    Published 2015-02-01
    “…In order to meet the needs of energy saving in wireless networks,a power control strategy with joint of multi-packet reception and fuzzy logic was proposed.Firstly,based on the power control with successive interference cancellation (SIC),transmission power was divided into several decodable power levels.Secondly,fuzzy logic control algorithm was adopted to select the optimal transmission power for SIC.In addition,three parameters were designed as fuzzy logic control inputs for power selection,which were the distance between transmitters and receivers,the number of neighboring nodes and the residual energy of transmitters.Simulation results show that power control strategy with joint of multi-packet reception and fuzzy logic control not only betters average network throughput than other power control strategy for SIC,but also saves more energy so that the network lifecycle would be significantly extended.…”

    Cache replacement strategy based on content value by Dan HUANG, Rongfang SONG

    Published 2018-11-01
    “…The cache replacement mechanism is one of the important research issues of the content center network.Considering the limited cache space,the reasonable replacement of the cache content becomes a key factor affecting the overall performance of the network.Therefore,a cache replacement scheme based on content value was designed.Considering the dynamic popularity of content,the cost of caching,and the time of the most recently requested,a more realistic content value function was built,and an effective content storage and replacement scheme was designed based on the content value function.Specifically,when the cache space was insufficient,the existing cache contents were replaced according to the value from small to large.Simulation results show that compared with the traditional replacement algorithms LRU,LFU and FIFO,the proposed scheme effectively improves the content cache hit rate of network nodes and reduces the average hops of users’ content acquisition.…”

    Performance analysis of packet cooperative relaying system and the effect of packet length on performance by Shao-yang LIU, Yong XI, Ying LI, Ji-bo WEI, LISTERBurr A

    Published 2012-09-01
    “…The packet error rate(PER)of the packet cooperative relay system for both(amplify-and-forward)and DF(decode-and-forward)schemes in the high signal-to-noise ratio(SNR)region was analyzed,and the effect of packet length on PER performance was studied.It is shown that both AF and DF achieve the same diversity gain in terms of PER,but with different coding gains depending on packet length.Different from the prior research,if considering prac-tical packet lengths,the DF scheme always achieves better performance than the AF scheme,with shorter packet length,the advantage of DF over AF is more obvious.For large enough packet length,AF performance approaches that of DF.It is also found that the optimal relay will always be located in the middle of the two nodes for AF regardless of packet length,while for DF,when packet length becomes large,the optimal relay moves from close to the source towards the midpoint.…”

    Published 2021-08-01
    “…The development and application of blockchain technology makes it possible to build a more robust and flexible botnet command and control channel.In order to better study this type of potential new botnet threats, a highly confrontational botnet model based on blockchain smart contracts-SCBot was proposed.The SCBot model adopts a hierarchical hybrid topology structure, builds a command transmission channel based on smart contracts at the zombie subnet layer, and establishes a credibility evaluation mechanism to determine the authenticity of nodes, and enhances the confrontation of the network from the two major levels of traffic and terminals.The construction of small botnet clusters were simulated, comparative experiments on SCBot's command transmission efficiency and robustness were conducted, and its feasibility in the real environment from the perspective of economic costs was analyzed.Finally, a brief analysis and discussion of the defense strategy of this type of botnet were given.…”
