Efficient Content Delivery for Mobile Communications in Converged Networks

Abstract

The mobile Internet is already playing a key role in people’s daily lives worldwide, resulting in the dramatic growth in the number of mobile devices. The size of the Internet and the amount of the traffic are being expanded rapidly, which poses various challenges. In particular, the Internet and mobile communications are entering a new era that demands faster communication services and uninterrupted content delivery. A new paradigm called content-centric networking (CCN) is considered as an appropriate way for efficient content delivery. In this paper, we propose a CCN-based efficient content delivery mechanism in the 4G network and also in the upcoming 5G network where various heterogeneous networks are converged. We also propose a novel mobility management scheme to support the content diversity and network diversity by leveraging the abundant computational resources in the mobile network. In addition, we analyze the existing approaches with respect to mobility and evaluate the performance of our seamless content delivery mechanism in terms of content transfer time, throughput, and data transmission success ratio. Simulation results are also presented to show that the content-centric wireless network with our mobility management scheme can improve the data delivery services significantly compared to the existing schemes.

Design of a Novel Architecture for Cost-Effective Cloud-based Content Delivery Network

“…The study has also used the Lyapunov optimization approach that emphasizes mobile nodes' activity connected with the operator. Another study carried out by Bosunia, and Jeong [20] addresses the challenges associated with the growing mobile internet market that affects seamless content delivery. The study has presented the usage of content-centric networking to carry out content delivery in the presence of a converged network.…”
