In light of the recent advancements made in IT, many researchers are studying and exploring ways to minimize damage from fire disasters using artificial intelligence and cloud technology. With the introduction of edge computing, firedisaster response software systems have made significant progress. However, existing studies often do not consider the response to a sudden power supply cut-off due to fire. In this study, we propose a container migration scheme based on the first-fit-decreasing algorithm of bin-packing problem and 0-1 knapsack algorithm to provide fault tolerance for containers running on edge servers that are powered off.

본 논문에서는 엣지 컴퓨팅 장치에서 쿠버네티스의 네트워크 성능 제어 방식이 실제 컨테이너 네트워크 성능에 미치 는 영향을 실험을 통해 제시한다. 컨테이너의 네트워크 성능은 엣지 컴퓨팅 환경에서 서비스 품질에 큰 영향을 미치 는 요소로 네트워크 성능이 저하되는 경우 데이터 전송에 걸리는 시간이 늘어나고 사용자 요청에 대한 응답시간이 길어지는 등의 서비스 품질 저하를 야기할 수 있다. 본 논문의 실험 결과, 엣지 컴퓨팅 환경에서 쿠버네티스의 네트 워크 성능 제어 방식을 적용하는 경우, 1) 사용자가 요청한 네트워크 성능에 달성하는데 상당한 시간이 소요되며, 2) 요청한 네트워크 성능 수치를 제대로 달성하지 못하는 문제가 있음을 확인하였다. 이를 통해, 쿠버네티스를 이용 한 네트워크 성능 제어를 위해서는 엣지 컴퓨팅 환경의 특성을 고려한 새로운 기법의 개발이 필요함을 알 수 있다.

This paper empirically demonstrates the ramifications of Kubernetes' network performance control methodologies on the network performance of containers within edge computing devices. Our experimental findings corroborate that the application of Kubernetes' network performance control methodologies within edge computing environments is characterized by: 1) a significant temporal investment required to attain user-requested network performance, and 2) inadequacies in achieving the stipulated network performance metrics. Thus, it is evident that the development of novel techniques tailored to the distinctive attributes of edge computing environments is imperative for proficient network performance control leveraging Kubernetes.

Thanks to the development of information technology and the vitalization of smart services, the Internet of Things (IoT) technology, in which various smart devices are connected to the network, has been continuously developed. In the legacy IoT architecture, data processing has been centralized based on cloud computing, but there are concerns about a single point of failure, end-to-end transmission delay, and security. To solve these problems, it is necessary to apply decentralized blockchain technology to the IoT. However, it is hard for the IoT devices with limited computing power to mine blocks, which consumes a great amount of computing resources. To overcome this difficulty, this paper proposes an IoT architecture based on the edge computing technology that can apply blockchain technology to IoT devices, which lack computing resources. This paper also presents an operaional procedure of blockchain in the edge computing-based IoT architecture.

Urban traffic congestion leads to prolonged delays, elevated emissions, and diminished safety across arterial networks. This paper proposes an edge‑native framework for intersection control that combines smart‑pole edge computing with federated multi‑agent reinforcement learning. Lightweight agents at each intersection learn locally from on‑pole sensors while a privacy‑preserving federated procedure periodically aggregates model updates across the network. The communication layer integrates IEEE 802.11p for low‑latency local V2X exchange and MQTT 5.0 for monitoring and model coordination. Evaluation is conducted in a digital‑twin‑in‑the‑loop environment that couples VEINS (OMNeT++–SUMO) with Simu5G to account for 802.11p and NR‑V2X link behavior. Emissions are estimated using SUMO’s HBEFA‑based model. Compared with fixed‑time, actuated, and non‑federated MARL baselines, the proposed approach shows the potential to reduce network‑wide average delay and queue length while simultaneously lowering CO₂ and NOx. The paper details the architecture, the learning and communication design, and a reproducible protocol for scenario construction, metrics, and statistical testing.

In recent times, Edge computing technology is rapidly growing at a faster rate offering users a better performance for processing real-time applications in comparison with the traditional cloud computations. In the edge computing model, there are edge nodes grouped together, forming edge clusters for application services. The development of service migration technology in the Kubernetes environment complements the reliability and stability of the edge cloud management during the migration process. It automatically replicates the data changes on the edge server, and ultimately, there is no data loss or service failure, ensuring that the system is fully operational. In this paper, the proposed method of migration aims to provide uninterrupted service operation between the edge nodes in the event of a service failure. The preliminary experimental result performs the health check of containers in the pod which is used to identify the cause of service failure.

최근 횡단보도 및 교차로에서 보행자 충돌사고 예방의 중요성이 증가하고 있다. C-ITS 서비 스에서 이러한 사고를 줄이기 위하여 보행자 충돌방지 경고 서비스를 제시하고 있다. 그러나 현재 C-ITS 표준에 따른 보행자 충돌방지 경고 서비스는 현장의 카메라에서 보행자를 바로 검 출하여 서비스를 제공하는 것이 아니라 관제 센터의 영상분석 서버에서 보행자를 검출하고 ITS 시스템과 연계하여 서비스를 제공하기 때문에 실시간성을 만족하기 어렵다. 본 논문에서 는 엣지 카메라를 이용하여 현장에서 보행자를 검출하고 검출결과를 V2X 인프라를 통해 바로 운전자에게 제공하는 보행자 충돌방지 경고 시스템을 제안하고, 구현한 후 성능 평가를 시행 하였다. 평가 결과, 최악의 상황에서도 보행자 충돌방지 경고 메시지를 C-ITS 표준에서 요구하 고 있는 300ms 이내의 지연시간을 만족하여 전달할 수 있음을 확인하였다.

The prevention of pedestrian accidents in crosswalks and intersections is very important. The C-ITS services provide a warning service for preventing accidents between cars and pedestrians. In the current pedestrian collision prevention warning service according to the C-ITS standard, however, it is difficult to provide real-time service because it detects pedestrians from a video-analysis server in the control center and sends service messages through the ITS system. This paper proposes a pedestrian collision-prevention warning system that detects pedestrians in the local field using an edge camera and sends a warning message directly to the driver through a roadside unit. An evaluation showed that the proposed system could deliver the pedestrian collision prevention-warning message to the driver satisfying the delay time within the 300 ms required by the C-ITS standard, even in the worst case.

Future internet aims to function as a neutral in-network storage and computation platform, essential for enabling 6G and beyond wireless use cases. Information-Centric Networking and Edge Computing are key paradigms driving this vision by offering diversified services with fast response times across heterogeneous networks. This approach requires effective coordination to dynamically utilize resources like links, storage, and computation in near real-time within a non-homogenous and distributed computing environment. Additionally, networks must be aware of resource availability and reputational information to manage unknown and partially observed dynamic systems, ensuring the desired Quality of Experience (QoE). This paper provides a comprehensive evaluation of edge computing technologies, starting with an introduction to its architectural frameworks. We examine contemporary research on essential aspects such as resource allocation, computation delegation, data administration, and network management, highlighting existing research gaps. Furthermore, we explore the synergy between edge computing and 5G, and discuss advancements in 6G that enhance solutions through edge computing. Our study emphasizes the importance of integrating edge computing in future considerations, particularly regarding sustainable energy and standards.

The emergence of Multi-Access Edge Computing (MEC) technology aims to extend cloud computing capabilities to the edge of the wireless access networks, i.e., closer to the end-users. Thus, MEC-enabled 5G wireless systems are envisaged to offer real-time, low-latency, and high-bandwidth access to the radio network resources. Thus, MEC allows network operators to open up their networks to a wide range of innovative services, thereby giving rise to a brand-new ecosystem and a value chain. Furthermore, MEC as an enabling technology will provide new insights into coherent integration of Internet of Things (IoT) in 5G wireless systems. In this context, this paper expounds the four key technologies, including Network Function Virtualization (NFV), Software Defined Networking (SDN), Network Slicing and Information Centric Networking (ICN), that will propel and intensify the integration of MEC IoT in 5G networks. Moreover, our goal is to provide the close alliance between MEC and these four driving technologies in the 5G IoT context and to identify the open challenges, future directions, and concrete integration paths.

Edge computing has emerged as a promising paradigm for addressing the latency, bandwidth, and scalability challenges associated with traditional cloud-centric architectures. Computation offloading, the process of transferring computational tasks from edge devices to more powerful remote servers or cloud infrastructure, plays a crucial role in optimizing performance and resource utilization in edge computing systems. However, traditional computation offloading techniques often face limitations related to latency, network dependency, and scalability. In this survey, we explore the integration of digital twin (DT) technology into edge computing environments to empower intelligent computation offloading decisions. DTs, virtual representations of physical entities or systems that mirror their real-world counterparts, offer opportunities to enhance situational awareness, optimize resource allocation, and enable more informed decision-making at the edge. We provide a comprehensive overview of DTs empowered intelligent computation offloading, covering the fundamentals of DTs, traditional computation offloading techniques, and their limitations in edge computing. Additionally, we discuss how DTs can address these challenges and improve computation offloading strategies, along with practical applications and use cases across various domains. Finally, we identify open research challenges and opportunities for future exploration in this emerging field. Through this survey, we aim to provide researchers, practitioners, and stakeholders with insights into the potential of DTs to revolutionize computation offloading for edge computing and drive innovation in this rapidly evolving area.

Along with the proliferation of the Internet of Things (IoT) and the surge in the use of artificial intelligence (AI), Edge Computing has proved considerable success in reducing latency, network traffic consumption, and security risks. The convergence of AI and Edge Computing, emerging a brand-new paradigm called edge intelligence, has been expected to unleash the full potential of intelligent IoT services. Unfortunately, integrating AI and Edge Computing into IoT is highly challenging due to the concerns over IoT device performance, energy efficiency, and privacy. In this paper, we present brainyEdge, an AI-enabled framework for edge devices able to jointly satisfy the Quality of Experience (QoE) criteria of IoT applications. We enhanced the intelligence of AI models operating at edges by designing a learning procedure consisting of transfer learning and incremental learning to dynamically retrain the models with personalized and incremental data locally stored. These data are classified into private data permanently stored in edges and public data shared in the cloud. This increases the edge-cloud collaboration level while preserving data privacy. To minimize the network cost of deploying the models to edge devices, we developed a lightweight deployment paradigm supporting cloud-compression and edge-decompression based on a user-desired compression ratio. Our prototype-based evaluation results indicate the superiority of brainyEdge over a typical edge-cloud paradigm.

This paper investigates QoS-aware computation offloading issues for mobile edge computing in the 6G network. To minimize the end-to-end delay, we harness the Information-Centric Network (ICN) to ensure resource-constrained mobile user offloading computation-sensitive tasks in a distributed manner. Then, a two-stage approach based on a Multi-Agent Reinforcement Learning (MARL) algorithm entwined with optimization-embedding offloading ratio is proposed to enhance server selection for load balancing. Numeral results demonstrate that, with reference to a workshop-scale scenario, the proposed method can achieve outperformed performance in reducing delay and balancing loads on edge servers than the other four baseline schemes.

In the centralized architecture of traditional mobile cellular network, every traffic of mobile terminals has to traverse the centered network core and then deliver to the corresponding service mobile terminals. Since the traffic load is concentrated on the central network core, it is difficult to deliver the explosive amount of network traffic and guarantee latency requirements of diversifying applications. In order to solve this problem, the mobile edge computing (MEC) architecture that distributes the traffic load by locating the computing and caching server closer to the terminal is currently being developed. In this paper, the effect of distribution of mobile traffic with MEC is evaluated in terms of throughput enhancements and latency reduction. The simulations were conducted using Mininet to determine what performance gains can be obtained when applying the MEC architecture to the mobile cellular network. As a result, under the same link bandwidth condition, MEC architecture provides an increase in data rates of approximately 265% for high-quality video transmission and about 162% for low-quality video transmission, and shows the reduced delay of packet arrival times.

Despite the rapid growth of the Internet industry, the provision of full Internet service to remote regions is still challenging. As a solution, the combination of Low Earth Orbit (LEO) satellite communication and Mobile Edge Computing (MEC) is gaining attention. However, considering the high speed of LEO satellites in network environments remains a significant challenge. To this end, this paper introduces a dynamic computation offloading and resource allocation framework in the LEO satellite MEC architecture. Using Lyapunov optimization, we propose an efficient DCOOL algorithm to minimize average power consumption and propagation delay constrained by queue stability. Finally, comparative analysis and simulations demonstrate the superior performance of DCOOL while achieving lower power consumption and stable workload processing.
