Study of Adaptive Dynamic Replication Mechanism in Mobile Edge Computing Environment

With the Internet of Things becoming popular in recent year, the network system must provide resource-intensive and time-critical applications to mobile users. Under such circumstances, researchers must overcome some problems which will impede the progress or achievement. Basically, these problems can be improved by offering ultra-short latency and less core network traffic under Mobile Edge Computing (MEC) environment. But when more users run mobile online applications in the MEC network, it will generate massive updates for replicas resulting in additional traffic overhead. To make system to improve the Quality of Services (QoS), we propose an effective Adaptive Dynamic Replication Mechanism (ADRM) protocol to enhance the availability, access efficiency and load balancing in the MEC environment. The main protocol is to pick out popular files and adjust the number of replica based on the ratio of replica. This can help us to improve the overall performance of the system.
