Recently, new mobile applications and services have appeared thanks to the rapid development of mobile devices and mobile network technology. Cloud computing has played an important role over the past decades, providing powerful computing capabilities and high-capacity storage space to efficiently deliver these mobile services to mobile users. Nevertheless, existing cloud computing delegates computing to a cloud server located at a relatively long distance, resulting in significant delays due to additional time to return processing results from a cloud server. These unnecessary delays are inconvenient for mobile users because they are not suitable for applications that require a real-time service environment. To cope with these problems, a new computing concept called Multi-Access Edge Computing (MEC) has emerged. Instead of sending all requests to the central cloud to handle mobile users’ requests, the MEC brings computing power and storage resources to the edge of the mobile network. It enables the mobile user device to run the real-time applications that are sensitive to latency to meet the strict requirements. However, there is a lack of research on the efficient utilization of computing resources and mobility support when mobile users move in the MEC environment. In this paper, we propose the MEC-based mobility management scheme that arranges MEC server (MECS) as the concept of Zone so that mobile users can continue to receive content and use server resources efficiently even when they move. The results show that the proposed scheme reduce the average service delay compared to the existing MEC scheme. In addition, the proposed scheme outperforms the existing MEC scheme because mobile users can continuously receive services, even when they move frequently.

ZONE-Based Multi-Access Edge Computing Scheme for User Device Mobility Management

The Multi-Access Edge Computing (MEC) paradigm provides a promising solution to solve the resource-insufficiency problem in user mobile devices by offloading computation-intensive and delay-sensitive computing services to nearby edge nodes However, there is a lack of research on the efficient task offloading and mobility support when mobile users frequently move in the MEC environment In this paper, we propose the mobile personal MEC architecture that utilizes a user’s mobile device as an MEC server (MECS) so that mobile users can receive fast response and continuous service delivery The results show that the proposed scheme reduces the average service delay and provides efficient task offloading compared to the existing MEC scheme In addition, the proposed scheme outperforms the existing MEC scheme because the existing mobile user devices are used as MECS, enabling low-latency service and continuous service delivery, even as the mobile user requests and task sizes increase

Mobile Personal Multi-Access Edge Computing Architecture Composed of Individual User Devices

As the media services' usage and internet accessible mobile devices' propagation are increased, a large amount of content generation and content sharing have taken place in real time Therefore, mobile networks are the critical constituents in the future network To meet this trend, the content-centric networking (CCN) is considered as the typical future network architecture However, in the CCN, the movement of mobile devices (especially mobile content sources) leads to many problems like frequent routing updates, high resource consumption and repeated retransmission of interest packet So, this paper proposes pre-allocated tentative name prefix mechanism for efficient fast mobility management in CCN environment The proposed mechanism utilizes pre-allocated tentative name prefix pool for the fast mobility Therefore, the proposed mechanism provides low interest message overhead and low resource consumption

Pre-allocated duplicate name prefix detection mechanism using naming-pool in mobile content-centric network

As the social networking and video services’ usage is increased, explosive content creation and content sharing has taken place. Therefore, to meet growth of users’ demands, new network architectures are required and then many researcher works for content-centric networking have been actively underway. However, in the content-centric network, mobile content sources create many problems like frequent routing update or many retransmission of interest packet. To solve these problems, tunnel-based redirection (TBR) scheme was proposed. However TBR scheme wastes network resource due to long latency of duplicate name prefix detection (DND) processing. So, this paper proposes a fast DND mechanism in mobile CCN environment to provide lower overhead and to access content data fast.
