Design and Analysis of a D2D based System for Contents Transfer

Content transfer amount, which is based on mobile communication networks in the development of applications for many applications and the dissemination of rapid smart devices, has increased. However, as mobile data traffic increases rapidly, limits appear in the content delivery of mobile communication network base. (D2D) technology solves the limitations of content delivery network-based mobile phones to communicate between devices. However, this feature of D2D communication technology causes a problem of device overhead; in this paper, we propose a system that can reduce such overhead of D2D communication devices. By performing only one role specified for each device, overhead can be reduced, and a high performance of content delivery is allowed. By performing experiments for content distribution in consideration of multi-national communications, device mobility, and travel through application implementation, we can measure and analyze content speed and transfer rate. This reduces device overhead in D2D communication technology; it is expected that the provision of many more services is possible in the future.
