An Efficient Data Transmission Technique for Big Video Files over HetNet in Emerging 5G Networks

Abstract

This paper proposes an efficient data transfer scheme for mobile big video files over HetNet in emerging 5G networks, along with a data correction technique to deal with the problem of failure to retrieve the stored data. The proposed scheme exploits the possibility of overlapping coverage received by a UE from multiple base stations (BSs) in HetNets to expedite the mobile big data transfer between the UE and the cloud storage center. This is achieved by compressing a big video file into smaller sized file, then splitting the compressed file into a number of smaller chunks, which are transmitted simultaneously over the multiple data links. Simulation results demonstrate that our proposed method outperforms the baseline data storage method.
