    The VehicleAd Hoc Network PerformanceAnalysis Based on Rayleigh Decay Model
    HUANG Meng-yao WANG Yu TANG Chen YU Jing WANG Qin
    Computer & Telecommunication. 2021, 1 (3): 1-6.   DOI: 1008-6609(2021)03-0001-06
     This paper mainly studies on the performance of vehicle ad hoc network based on Rayleigh decay channel. Considering
    the highway scenario, this paper analyzes several network performance indicators of vehicle communication with roadside units,
    such as interrupt probability, packet error probability, average packet loss probability, and so on. Numerical simulation is performed
    to discuss the effects of different parameters on these network performance indicators, including the size of the competition window,
    the size of the packet, the number of vehicles, the speed of the vehicle, and the arrival rate of the packet. Simulation results show
    that the proposed network performance analysis model is valid. This model can be used to analyze the influence of various parame-
    ters on the performance of the off-road communication network in highway scenarios, and provide reference for designing a reason-
    able roadside unit deployment scheme.

    Intrusion Detection Method Based on Cluster Analysis and Transfer Learning
    HUANG Qing-lan
    Computer & Telecommunication. 2021, 1 (3): 13-15.   DOI: 1008-6609(2021)03-0013-03
    When the distribution of training and test samples is inconsistent, the main problem for the practical application of traditional machine learning algorithms in intrusion detection is that the detection accuracy is low. To solve the problem, this paper proposes an instruction detection method based on clustering analysis and transfer learning. Firstly, the hierarchical sampling technology based on clustering is used to obtain a small amount of labeled data for transfer classification training, so that the distribution of data for transfer classification is as similar as possible to the data distribution to be detected. Then the simple transfer classification model is applied to the field of intrusion detection. The experimental results on the NSL-KDD data set show that the detection method has higher detection accuracy than the traditional machine learning algorithms

    Simulation Modeling of Cognitive Radio Spectrum Allocation Based on Graph Theory Model
    LIU Xinhao MA Xin-rui WANG Da-wei
    Computer & Telecommunication. 2021, 1 (3): 16-20.   DOI: 1008-6609(2021)03-0016-05
    According to the availability and interference conditions of spectrum allocation, it is a major feature of the existing re-search to abstract the network composed of cognitive users into a graph, and promote the study of spectrum allocation by graph theo-ry. The final spectrum allocation strategy is usually recorded in the non-interference allocation matrix, but the problem of high cod-ing dimension often exists when it is encoded directly. In order to simulate and model cognitive radio spectrum allocation more effi-ciently, the availability matrix is extracted and encoded and reduced to one-dimensional matrix. After optimization, the availabilitymatrix is restored according to the original corresponding relationship, so as to better reduce the coding dimension and the spatial di-mension of understanding. Experimental results show that this method can complete simulation modeling of radio spectrum alloca-tion more efficiently and quickly.

    Research on the Detection of Abnormal Behavior of College StudentsBased on Density Peak Clustering
    LI Hui-fang ZHONG Xin-cheng FU Xiao-li
    Computer & Telecommunication. 2021, 1 (3): 26-29.   DOI: 1008-6609(2021)03-0026-04
    The detection of abnormal behavior of college students is a worthy research topic in college student management, whichhelps universities to evaluate abnormal student populations scientifically and quickly. Aiming at the lagging management methodssuch as traditional questionnaire survey and regular screening in universities, this paper proposes an algorithm to detect the abnormalbehavior of college students based on feature-weighted density peak clustering. The algorithm first adopts the Euclidean distance ofthe weighted feature to represent the sample distance, then uses the density peak clustering to classify the student samples without la-bel, and finally distinguishes the sample points whose local density does not exceed the boundary density as abnormal points.

    Computer & Telecommunication. 2021, 1 (3): 52-55.   DOI: 1008-6609(2021)03-0052-04
    In the process of getting Wechat user information in the login process of Wechat applet, it is necessary to carry out a num-ber of related asynchronous request operations to obtain the user's encrypted information, and then decrypt and return it. The tradi-tional nested method of asynchronous callback results in poor program readability and low program execution performance. Theemergence of Promise solves the problem of multiple asynchronous operation requests when Wechat applet obtains Wechat user in-formation. It divides the asynchronous request function more clearly, greatly improves the readability of the program, and providesgood error handling logic.

    The private cloud platform of China Mobile enterprise has five technical characteristics, namely, the integration of cloudnetwork side, super-large scale, cloud native architecture, independent control, and full stack base. In the current operation and man-agement of cloud platform, to ensure the effective use of company resources, an effective means is to analyze the user value of theplatform. For a long time, there has been a lack of scientific analysis means in this aspect, and the discriminant method based on per-sonal experience is often adopted, which lacks reliability. This paper puts the values of private cloud users into five dimensionswhich are resource utilization, resources rationality, user economy value, science and technology innovation value, politic and man-agement. It constructs the feature engineering and model algorithm based on user basic data, and establishes the evaluation methodfrom two aspects of expert evaluation model and objective scoring model, outputting user value scores and selecting high value us-ers
