The business of Internet of Vehicles (IoV) is growing rapidly, and the large amount of data exchange has caused problems of large mobile network communication delay and large energy loss. A strategy for resource allocation of IoV communication based on mobile edge computing (MEC) is thus proposed. First, a model of the cloud-side collaborative cache and resource allocation system for the IoV is designed. Vehicles can offload tasks to MEC servers or neighboring vehicles for communication. Then, the communication model and the calculation model of IoV system are comprehensively analyzed. The optimization objective of minimizing delay and energy consumption is constructed. Finally, the on-board computing task is coded, and the optimization problem is transformed into a knapsack problem. The optimal resource allocation strategy is obtained through genetic algorithm. The simulation results based on the MATLAB platform show that: The proposed strategy offloads tasks to the MEC server or neighboring vehicles, making full use of system resources. In different situations, the energy consumption does not exceed 300 J and 180 J, with an average delay of 210 ms, effectively reducing system overhead and improving response speed.

Internet development requires the evaluation of secure Internet service quality. This study evaluated public Internet service quality categories and items based on the eQual program developed by Barnes & Vidgen (2006). Using a questionnaire designed to test Internet service qualities for public websites designed by The Knowledge and Information Resources Management Project, we examined 707 users and then measured the effects of service quality factors on customer satisfaction. In conclusion, we found that information quality, usability, and service interaction had a positive effect on customer satisfaction.

Scheduling plays a dynamic role in cloud computing in generating as well as in efficient distribution of the resources of each task. The principle goal of scheduling is to limit resource starvation and to guarantee fairness among the parties using the resources. The demand for resources fluctuates dynamically hence the prearranging of resources is a challenging task. Many task-scheduling approaches have been used in the cloud-computing environment. Security in cloud computing environment is one of the core issue in distributed computing. We have designed a deep learning-based security model for scheduling tasks in cloud computing and it has been implemented using CloudSim 3.0 simulator written in Java and verification of the results from different perspectives, such as response time with and without security factors, makespan, cost, CPU utilization, I/O utilization, Memory utilization, and execution time is compared with Round Robin (RR) and Waited Round Robin (WRR) algorithms.

Cloud computing promises high performance and cost-efficiency. However, most cloud infrastructures operate at a low utilization, which greatly adheres cost effectiveness. Previous works focus on seeking efficient virtual machine (VM) consolidation strategies to increase the utilization of virtual resources in production environment, but overlook the under-utilization of backup virtual resources. We propose a heuristic time sharing policy of backup VMs derived from the restless multi-armed bandit problem. The proposed policy achieves increasing backup virtual resources utilization and providing high availability. Both the results in simulation and prototype system experiments show that the traditional 1:1 backup provision can be extended to 1:M (M≫1) between the backup VMs and the service VMs, and the utilization of backup VMs can be enhanced significantly.

At present, more than 300 races of the Silkworm are conserved and used as valuable genetic resources. But because of the uneffectiveness of manual data management, faster and systematic data base construction is needed. So, development of silkworm genetic resources management program has been begun and the result can be practically used. When developing the program, Visual basic was used for data input system construction, and MS Access for database. IIS(Internet Information System) and ASP(Active Server Page) was also used for searching data and information with Internet Web Server and Web Browser which is comfortable for constructing database and providing information. Data input item consists of 46 practical characteristics such as race name, moltinism, larval period and pupation percentage etc.. And these characteristics are classified with qualitative and quantitative character. Photographs of silkworm, cocoon and other related items were scanned and the image data was recorded on the database.

The popularization of streaming networks and mobile devices brings a new kind of network called mobile peer-assisted streaming network. In this network, service provider not only offers downloading services, but also pre-pushes resources to users for caching. Users can download their demanded resources while working as servers for uploading the cached data. Also the mobile characteristic makes high package losing probability in this network. So we study how the service provider pre-pushes or the user downloads resources efficiently and effectively while considering the package losing in this paper. We build utility models for service provider and user, and solve the models using Bellman's theory to achieve Nash Equilibrium which shows the service provider's optimal pre-pushing speed and user's optimal downloading speed. The numerical simulation demonstrates the efficiency and effectiveness of our proposed pre-pushing and downloading scheme by comparing to the traditional scheme.

With the rapid development of information and communications technology, the construction of efficient, reliable, and safe Internet of Things (IoT) is an inevitable trend in order to meet high-quality demands for the forthcoming 6G communications. In this paper, we study a secure intelligent reflecting surface (IRS)-assisted IoT system where malicious eavesdropper trying to sniff out the desired information from the transmission links between the IRS and legitimate IoT devices. We discuss the system overall performance and propose a hybrid resource allocation scheme for maximizing the secrecy capacity and secrecy energy efficiency. In order to achieve the trade-off between transmission reliability, communication security, and energy efficiency, we develop a quantum-inspired marine predator algorithm (QMPA) for realizing rational configuration of system resources and prevent from eavesdropping. Simulation results demonstrate the superiority of the QMPA over other strategies. It is also indicated that proper IRS deployment and power allocation are beneficial for the enhancement of system overall capacity.

인터넷 상의 불법 유해 정보의 존재는 규제 당국뿐만 아니라 공공도서관과 학교를 비롯하여, 인터넷 서비스를 제공하는 모든 공공정보자원에서 큰 고민거리가 되어온 지 오래다. 특히 현대 정보사회에서 정보자원의 조직과 정보의 공개, 제공 및 이용서비스를 주 임무로 하고 있는 공공도서관의 경우 도서관 이용자들에 대한 인터넷 서비스의 제공은 필수적이라 할 수 있다는 측면에서 인터넷 정보를 둘러싼 규제 환경의 변화는 공공도서관 서비스 전반에 직접적인 영향을 미칠 수 있다. 1990년대 중반부터 본격화된 인터넷 정보에 대한 규제는 인터넷의 고유한 매체특성으로 인하여 법제도적 규제와 함께 기술적 규제 방식이 적극적으로 활용되어 왔다. 그러나 기술적 규제 방식 또한 각 나라마다. 매우 다양한 모습으로 발전하여 왔고, 더욱이 도서관 등과 같은 공공정보자원에서의 기술 규제는 표현의 자유와 알권리, 정보접근원의 침해라는 비판을 받아왔다. 이 글은 인터넷 규제와 표현의 자유에 대한 이론적 논의들로 시작하여, 인터넷에 대한 기술적 규제 방식으로 폭넓게 활용되고 있는 필터링 소프트웨어의 기술적 측면을 살피고, 인터넷 필터링을 중심으로 한 각국의 규제 양상을 비교 분석한다. 이를 통해 공공정보자원에서의 인터넷 필터링을 둘러싼 문제들에 대해 비판적으로 논의하고자 한다.
