Dynamic P2P trust model based on time-window feedback mechanism by SHI Zhi-guo, LIU Ji-wei, WANG Zhi-liang

“…The trust models employed by the existing systems do not provide adequate support to cope with dishonest feedbacks,strategically altering behaviors of malicious peers efficiently and the incentive mechanism.The time-window based local trust model TW-Trust was presented to solve these problems.It considers the inherent connection among trust,reputation and incentive and the effect of time factor on the trust computation.Six trust parameters are introduced to compute trustworthiness of peers,named direct trust,history reputation,difference reputation,misusing reputation,simi-larity and incentive utility.These parameters are adjusted in time to reflect the dynamic of the trust environment using feedback control mechanism,thus,the trust evaluation has better adaptability to the dynamic of trust.Theoretical analysis and experimental results show that the TW-Trust has advantages in countering strategic altering behavior and dishonest feedbacks of malicious peers and solving the sparseness issue in the computation of similarity.It is more effective in trust computation error and transaction failure rate than the previous models.…”

Application of step area algorithm in IDC traffic billing by Shizong LI, Zhihai CHEN, Yongming YAN

“…IDC customers reduce costs through traffic scheduling, which leads to waste of resources and increase of operation and maintenance costs of operators.Area billing could effectively improve this problem.It made a comparison between area billing and 95% peak rate billing method, and innovatively tried the step area algorithm.By connecting the difference between 95% peak rate value and average value and 95% peak rate billing and area billing price, the data dimension reduction was carried out, and the two-dimensional scatter diagram was obtained by programming exhaustive calculation, and the relationship between them was analyzed to explore the possibility of area billing.The experimental results show that the area of pricing could guide the customer does not adopt the way of traffic scheduling to reduce costs, in addition ladder area of billing way can meet the current traffic situation in the certain degree differ with 95 billing way smaller, the flow demand rises customers reduce costs, operators can get the corresponding profits at the same time, achieve a win-win situation.…”

Research on the architecture of space-ground integrated information network: integration of communication, networking and computing by Zhigang YU, Xu FENG, Zhaoxiang HUANG, Zhou LU

“…With the continuous expansion of human activities from the terrestrial to the ocean and space, the countries all over the world have advanced the layout of space-ground integrated information network to provide seamless coverage and ubiquitous connection services.Space-ground integrated information network is the deep integration of space network and terrestrial network, not the expansion of terrestrial network to space environment.Starting from the perspective of integration, firstly the development status, existing problems and challenges of the internet, public land mobile network (PLMN), and space networks were sorted out.Secondly, the research status of the space-ground integrated information network architecture and the development trend of the new network architecture such as cloudification and intelligence was summarized.Thirdly, a communication-networking-computing integrated space-ground integrated information network architecture was proposed from different dimensions: physical architecture, functional architecture (including the integrated communication system, the integrated network system and the integrated information system), physical-functional architecture mapping problem.Finally, the network architecture optimization problem was modeled as a multi-objective optimization problem.It was expected to provide valuable suggestions and references for the research, construction and standardization of space-ground integrated information network.…”

Intelligent phase imaging guided by physics models by Zhen LIU, Hao ZHU, You ZHOU, Zhan MA, Xun CAO

“…Implicit neural representation characterizes the mapping between the signal’s coordinate to its attributes, and has been widely used in the optimization of inverse problems by embedding the physics process into the loss function.However, the implicit neural representation is suffering the low convergence speed and accuracy from the random initialization of the network parameters.The meta-learning algorithm for providing implicit neural representation with a strong prior of network parameters was proposed, thus enhancing the optimization efficiency and accuracy for solving inverse problems.To address the important issue of lens less phase imaging, an intelligent method on phase imaging was proposed based on the snapshot lens less sensing model.By embedding the optical diffraction propagation theory into the design of loss function for implicit neural representation, the dependency of large-scale labelled dataset in traditional deep learning-based methods was eliminated and accurate phase image from a single diffraction measurement image was provided.Furthermore, the meta-learning model was introduced for initializing network to further improve the efficiency and accuracy of network training.Numerical simulation results show that the proposed method can achieve a PSNR improvement of more than 11 dB compared to the conventional method.The experimental results in real data show that the phase image reconstructed by the proposed method is clearer and has fewer artifacts.…”

Honeypot defense and transmission strategy based on offensive and defensive games in vehicular networks by Jie YI, Tengfei CAO, Shuai GAO, Jianqiang HUANG

“…With the rapid development of the Internet of Vehicles, service providers can efficiently provide caching services for vehicle users by deploying 5G base station-type RSUs adjacent to vehicles.However, due to the presence of malicious attackers, the controlled base station is turned to be malicious for the purpose of identity forgery attack.When messages are sent in the name of malicious base stations to interfere with the communication link between vehicles and the trusted base stations, it is easy to cause serious driving safety problems.To solve the above problem, an efficient transmission and honeypot defense strategy was proposed, which was based on the offensive and defensive game in the Internet of Vehicles to reduce the risk of identity forgery attacks and improve the security of data transmission.The interaction between trusted base stations and malicious base stations in the Internet of Vehicles scenario was modeled as an attack-defense game model.On this basis, trusted base stations and honeypot base stations were jointly used as defenders to defend against malicious attacks.Then, the trusted base station and the malicious base station, as the two sides of the offensive and defensive game, chose their respective strategies to construct a model of the benefit function of both sides.Combined with the vehicle delay feedback mechanism, the defender and the malicious base station dynamically adjusted their respective strategies.By adjusting the interaction between the honeypot base station and the vehicle, and also the degree of IP randomization, the overall benefit of the defender was effectively improved.Besides, the optimal solution was obtained by using the mixed strategy Nash equilibrium theory.Simulation experimental results show that the proposed strategy can improve the secure transmission performance of the Internet of Vehicles service in the presence of malicious attackers, and the defender’s expected benefit is improved by 48.9% and the data transmission delay is reduced by 57.1% compared to the no-honeypot defense scheme.…”

La acción psicosocial como praxis en psicología: Comprensiones desde las prácticas profesionales by Andrea del Pilar Arenas, Angela Ivethe Mayorga Ortegón

“…El procesamiento de información se llevó a cabo mediante análisis temático; iv) Resultados: la acción psicosocial se evidencia como una perspectiva de abordaje caracterizada por la interacción y la capacidad de transformación de una situación problémica en donde el profesional ejerce un rol horizontal privilegiando el saber subjetivo y colectivo, definida por la implementación de metodologías alternativas que conllevan un carácter reflexivo; v) conclusiones: la acción psicosocial como proceso interaccional y transformacional posibilita una ampliación de las perspectivas y concepciones imaginarias sobre la práctica más allá del ámbito clínico-privado.…”
