The 2018 International Workshop on Content Caching and Delivery in Wireless Networks (CCDWN)

Monday, May 7th, 2018


Call for Papers

Future and emerging wireless networks will pose extreme communication requirements such as very high throughput rates and very low latency, particularly in QoE sensitive applications such as multimedia content delivery. Currently, operators are striving to reduce the investment and maintenance costs for cellular systems. In this context, caching has been proposed as a technique that has the potential to reduce backhaul network traffic and improve content latency for the wireless user. Especially in 5G, caching is proposed as one of the most promising new technologies. The Content Caching and Delivery in Wireless Networks (CCDWN) workshop focuses on techniques that aim to achieve efficient content delivery to the end user in order to meet the stringent quality requirements of 5G wireless. The idea is to bring together experts in the field and discuss ways in which content caching, sharing and prefetching can play a leading role in future wireless networks.
Indicative research topics of high interest include but are not limited to:

  • Caching architectures e.g. Femto-Caching
  • Memory management, content prefetching and recommendation
  • Content placement, replication and delivery
  • Big Data Caching Analytics and Machine Learning
  • Caching in the datacentre
  • Coded Caching and related Information Theory aspects
  • 5G and Caching (IoT, D2D, edge computing)
  • Network economics caching issues
  • Interplay of Caching with wireless communications (PHY and MAC)
  • Green Caching
  • Content Delivery Networks and ICN
  • Stochastic cache models, scaling laws
  • Distributed and adaptive algorithms in CDNs/ICNs

This workshop aims to bring together people from different communities, including networking, communications, computer science, operation research, machine learning, and information theory to shed light on the latest developments in the field.
To maximize interaction and visibility, CCDWN 18 will be co-located with WiOpt 2018 and will take place on May 7, 2018, in Shanghai, China. The workshop is considered an integral part of the WiOpt 2018 symposium. All CCDWN papers will be published in the same set of proceedings as the main conference and will be made available on the IEEE Xplore. Publication at this workshop is not intended to preclude later publication of an extended version of the paper. At least one author of each accepted paper is expected to present his/her paper at the workshop.

    Talk title: Coded Caching for Wireless Interference Management


    Caching is an effective technique to alleviate peak-hour traffic congestion and improve user perceived experience for content delivery in wireless networks. Caching at the very edge of wireless networks, including small base stations, edge nodes, and user devices, differs from the traditional web caching in that it is able to exploit the broadcast nature of wireless medium and hence enjoy global caching gain. This is enabled by coded caching, a revolutionary way of using cache memory in wireless networks by splitting each file into multiple subfiles, then storing them in different cache nodes. In this talk, I will reveal the great promises of coded caching for wireless interference management. I will first present a storage-latency tradeoff study for a general wireless interference network where all the transmitters and receivers have caches. I will then extend the study to a fog radio access network (F-RAN) and discover the impact of shared wireless fronthaul on caching and delivery strategies in the interfering access link. I will also discuss coded caching in a large- scale interference-limited small-cell networks from a more practical design perspective. Finally, I will highlight some potentials of coded caching to accelerate computation-intensive services in wireless networks.

    2nd Keynote Seminar: 3:00pm-4:00pm

    Speaker: Edmund Yeh, Northeastern University

    Talk title: Data-Centric Networking: Lessons and Impact


    The past decade has seen the development of data-centric networking architectures such as Named Data Networking (NDN), which focuses on enabling end users to obtain the data they want, rather than to communicate with specific nodes. The transformation of data into a first-class network entity upends fundamental assumptions while opening up many new vistas for networking research. In this talk, we will review some of the lessons learned from the development of data-centric networking, and examine its impact on research in areas such as caching and routing. We will also discuss the potential benefits of data-centric designs for wireless edge networks as well as large-scale data-intensive scientific networks.


    Edmund Yeh received his B.S. in Electrical Engineering with Distinction and Phi Beta Kappa from Stanford University in 1994. He then studied at Cambridge University on the Winston Churchill Scholarship, obtaining his M.Phil in Engineering in 1995. He received his Ph.D. in Electrical Engineering and Computer Science from MIT under Professor Robert Gallager in 2001. He is currently Professor of Electrical and Computer Engineering at Northeastern University. He was previously Assistant and Associate Professor of Electrical Engineering, Computer Science, and Statistics at Yale University. He has held visiting positions at MIT, Stanford, Princeton, UC Berkeley, NYU, EPFL, and TU Munich.

    Professor Yeh was one of the PIs on the original NSF-funded FIA Named Data Networking project. He will serve as General Co-Chair for ACM Conference on Information Centric Networking (ICN) 2018 in Boston. He is the recipient of the Alexander von Humboldt Research Fellowship, the Army Research Office Young Investigator Award, the Winston Churchill Scholarship, the National Science Foundation and Office of Naval Research Graduate Fellowships, the Barry M. Goldwater Scholarship, the Frederick Emmons Terman Engineering Scholastic Award, and the President's Award for Academic Excellence (Stanford University). Professor Yeh has served as the Secretary of the Board of Governors of the IEEE Information Theory Society, as well as Associate Editor for IEEE Transactions on Networking, IEEE Transactions on Mobile Computing, and IEEE Transactions on Network Science and Engineering. He has received three Best Paper Awards, including awards at the 2017 ACM Conference on Information-Centric Networking (ICN), and at the 2015 IEEE International Conference on Communications (ICC) Communication Theory Symposium.
