IEEE Access invites manuscript submissions in the area of Wireless Caching Technique for 5G.

For the next-generation mobile network, the well-published technical target is to increase the network’s capacity by a factor of 1000 beyond 4G. Theoretically, this could be achieved through the use of i) 10x more cells, ii) 10x more spectrum, and iii) 10x higher spectrum efficiency. Although the three-pronged solutions may achieve the 1000x capacity increase, the growth in mobile traffic will also continue beyond 2020. Unfortunately, none of these three resource-demanding approaches offers a long-term solution. The nature of diminishing return due to the Shannon law deems such gains unsustainable. Clearly, alternative solutions are needed in mobile systems to achieve long-term sustainability.

In addition, traffic characteristics in mobile networks have changed profoundly over time and space. With the development of popular mobile applications, such as YouTube, WeChat, Netflix and Facebook, multimedia content constitutes nearly 80% of the total mobile traffic. However, only a small percentage (~5%) of the content is accessed by most of mobile users. In this situation, the mobile network is inundated with requests for the popular content. Mobile applications are undergoing a fundamental shift, from conventional “connection-centric” behaviors (e.g., phone calls, text messages) to a more “content-centric” usage model.

Unlike the communication resource, which is fundamentally limited by the bandwidth and power, the caching resource is abundant, economical, and sustainable. The growth of caching resource has been following the Moore’s low for the past five decades with little sign of slowing down. As a matter of fact, content caching technology can be widely used in mobile networks, e.g., the most popular contents cached in the base stations to alleviate the backhaul traffic. Essentially, the caching operations introduce non-causality into mobile networks, which increase the system capability to deliver information over longer period of time. Therefore, how to accommodate expanding mobile services through the use of such sustainable, non-communication resource (caching) for 5G has attracted significant research interests from both academia and industry.

This Special Section in IEEE Access has intended to review the economic opportunities, examine the technical challenges, and discuss possible paths to regulatory solutions. It will also bring together academic and industrial researchers to identify and discuss technical challenges and recent results related to wireless content caching for 5G technologies and forecast the future trends. The topics of interest for the special issue include, but are not limited to:

  • Theoretical framework of wireless caching for 5G
  • Network architecture and protocols
  • Mobile computing for caching
  • Big data enabled caching over wireless networks
  • Performance limits and bounds of caching in wireless networks
  • Wireless Caching-enabled HetNet
  • Coded Caching in Wireless Networks
  • Edge Caching techniques for 5G
  • Wireless Content Caching for D2D Networks
  • Content Caching and Delivery in Wireless Converge Networks
  • Energy Efficiency of Wireless Caching Networks
  • Resource allocation in Wireless Caching Networks
  • Interference management in cache-aided wireless interference networks

 

We also highly recommend the submission of multimedia with each article as it significantly increases the visibility, downloads, and citations of articles.
