“…In order to build a virtual reality system that can realistically simulate the real world, geometric modeling technology, physical modeling technology, and behavioral modeling technology must be combined [12]. In the virtual reality application environment, the virtual model is usually required to have autonomous intelligence in order to be able to interact with the user.…”

With the maturity of the most advanced technology and virtual reality, the application of digital media technology in various fields has become more and more extensive. Digital media technology has greatly promoted the development of all classes of society. Therefore, how to develop digital media technology applications has become a major issue. This article aims to study the digital media application technology of mobile terminals based on edge computing and virtual reality. In this paper, we use edge computing and virtual reality methods to study the digital media application technology of mobile terminals. We used the SD-CEN architecture and FWA in edge computing to conduct simulation experiments and compared the delay time performance of the FWA with that of the PSO-CO algorithm, WRR algorithm, and Pick-KX algorithm. The results of this paper show that it can effectively reduce the response delay of real-time face recognition services and improve user experience. Compared with the traditional cloud computing architecture and a single MEC device, the SD-CEN network architecture based on FWA strategy has more advantages. The latency of the FWA is increased by 61%, 46%, and 17%, respectively, compared with that of the WRR, Pick-KX, and PSO-CO algorithms.

“…In [15], the authors have investigated the Virtual Machines (VMs) placement problem in Mobile Edge Computing (MEC) architecture to minimize the delay. The authors in [16] have addressed the dynamic service placement problem on edge servers for the group virtual reality games to minimize operational costs while respecting the players' Quality-of-Service (QoS) requirements. In [17], a Mixed Integer Nonlinear Programming (MINLP) model for the joint VMs resource allocation and user request assignment problem has been presented to minimize the average response time.…”

Fog computing is a paradigm that extends cloud computing services to the edge of the network in order to support delay-sensitive Internet of Things (IoT) services. One of the most promising use-cases of fog computing is Smart City scenarios. Fog computing can substantially improve the quality of citywide services by reducing response delays. Owing to geographically distributed and resource-constrained fog nodes and a multitude of IoT devices in Smart Cities, efficient service deployment and end device traffic routing are quite challenging. Therefore, in this paper, we present an Integer Linear Programming (ILP) formulation for the Joint Application Component Placement and Traffic Routing (JAcPTR) problem in which users' delay requirements and the limited traffic processing capacity of application instances are considered. Besides, the JAcPTR enables users and infrastructure managers to easily enforce their locality and management requirements in the deployment of application instances. To cope with the considerably high execution time in large instances of the JAcPTR problem, we propose a fast polynomial-time heuristic to efficiently solve the problem. The performance of the proposed heuristic has been evaluated through extensive simulation. Results show that in large instances of the problem, while the state-of-the-art Mixed Integer Linear Programming (MILP) solver fails to obtain a solution in 50% of the simulation runs in 300 seconds, our proposed heuristic can obtain a near-optimal solution in less than one second.

When user turns head in an interactive Cloud VR service, such as the Cloud VR games, the black edge artifact often appears at the boundary of the viewport due to the inevitable latency, which significantly affects the user experience. In this paper, we focused on the interactive Cloud VR gaming services and investigated the influence of the black edge artifact on the user experience. The appearance of the black edge artifact during the playing period was regarded as a series of black edge events. The user experience on a single black edge event was first evaluated combining the influential factors of the area ratio and duration of the black edge artifact. Then, a pooling strategy was proposed to evaluate the user's overall experience. Experimental results showed that the proposed model can accurately predict the user experience that influenced by the black edge artifact for the Cloud VR services. This work can be served as a guideline for service providers and network operators to improve their services.
