The 4th International Workshop on Content Caching and Delivery in Wireless Networks (CCDWN)

June 15,  2020,

University of Thessaly

Call for Papers

The constantly increasing mobile data traffic, the proliferation of multimedia services, and the fast emergence of low-latency services challenge the performance and even the economic viability of today’s wireless networks. At the same time, fascinating developments, such as the software-based control of networks, the deployment of multi-tier wireless systems, and the interplay of caching with communication signals, create fresh opportunities for optimizing the network operation through storage resources. Indeed, storage and caching can play today an instrumental role in the success of wireless networks by increasing the performance of the offered services, reducing the Operating and Capital Expenditures, and by enabling new innovative business models.

The Content Caching and Delivery in Wireless Networks (CCDWN) 2020 workshop aspires to bring together experts from academia and industry to discuss the latest developments in the following, non-exhaustive, list of topics:

Information-theoretic caching analysis

  • Fundamental limits of coded caching
  • Coded caching design with practical constraints
  • Scaling laws of cache networks

Caching in beyond-5G wireless systems

  • HetNet and device-to-device caching
  • Cloud and wireless edge caching solutions
  • Caching and cross-layer optimization
  • Secure caching and privacy-constrained caching
  • Caching in high mobility networks

Content caching and delivery

  • Design of (elastic) content delivery networks
  • Algorithms for storage installation and content placement
  • Novel aspects of video caching and streaming
  • Caching economics, cooperation and incentive mechanisms for caching
  • Caching models for information centric networks

Data analytics for caching

  • Analysis of request data, time-varying content popularity models
  • Popularity estimation and prediction of viral content
  • Interplay of social networks and caching
  • Learning algorithms for caching optimization

Caching for (Edge) Computing

  • Deployment of services at the wireless network edge
  • Caching of code libraries and network functions
  • Service chains and caching in wireless networks

CCDWN ‘20 will be co-located with WiOpt 2020 and take place on June 15, 2020.

Talk title: Is Coded Caching the Missing Link in Wireless Communications?


Petros Elia received the B.Sc. degree from the Illinois Institute of Technology, and the M.Sc. and Ph.D. degrees in electrical engineering from the University of Southern California (USC), Los Angeles, in 2001 and 2006 respectively. He is now a professor with the Department of Communication Systems at EURECOM in Sophia Antipolis, France. His latest research deals with the intersection of coded caching and feedback-aided communications in multiuser settings. He has also worked in the area of complexity-constrained communications, MIMO, queueing theory and cross-layer design, coding theory, information theoretic limits in cooperative communications, and surveillance networks. He is a Fulbright scholar, the co-recipient of the NEWCOM++ distinguished achievement award 2008-2011 for a sequence of publications on the topic of complexity in wireless communications, and the recipient of the ERC Consolidator Grant 2017-2022 on cache-aided wireless communication.

Information for Authors


The submitted papers are expected to be six to eight (6-8) pages in the standard IEEE conference format. Submissions should be of sufficient detail to be evaluated by expert reviewers in the field. If full proofs cannot be accommodated due to space limitations, authors are encouraged to cite a publicly accessible long version of the submission that may be considered in the review.

WiOpt is technically co-sponsored by the IEEE Control Systems Society, IEEE Information Theory Society and IFIP. All papers will be published in the IFIP DL open library with Open Access, as well as on IEEE Xplore.
