2nd Content Caching and Delivery in Wireless Networks Workshop (CCDWN 2017), Paris, France, 15th May, 2017


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 poised as one of the most promising new technologies. The “Content Caching and Delivery in Wireless Networks (CCDWN) 2017” 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:

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 ‘17 will be co-located with WiOpt 2017 and will take place on May 15, 2017, in Paris, France. The workshop is considered an integral part of the WiOpt 2017 symposium.

Plenary Speakers

Coded caching and advanced PHY: Interesting interplays between caching, feedback and topology in wireless communications’

Petros Elia Eurecom, France

The slides to the talk are available here.


The talk will focus on coded caching and the interesting salient features that arise when caching is applied in advanced PHY wireless scenarios. Focusing on recently revealed deep connections between caching and fundamental primitives of wireless networks, such as feedback, multiple antennas, and topology, we will seek to answer different questions that arise, and which include:

We will also briefly look at how advanced PHY techniques can be used to ameliorate some of the bottlenecks of coded caching, exploring for example how interference enhancement techniques can be used to ameliorate the dreaded "worst-user" effect of coded caching.


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 considered different problems in the area of complexity-constrained communications, MIMO, cooperative and multiple access protocols and transceivers, complexity of communication, as well as with isolation and connectivity in dense networks, 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 communications.

Joint management of storage and network resources in software-defined wireless systems

George Iosifidis Trinity College Dublin, Ireland

The slides to the talk are available here.


SDN in conjunction with NFV offer a novel opportunity for the joint management of network, compute and storage resources. These technological advances can revolutionise the way we design and manage wireless systems, and eventually enable the operators to satisfy the increasingly stringent requirements of emerging services. We will discuss the latest developments in this area, while focusing on the particularly important application of mobile video delivery in 5G HetNets. A suite of network-aware video caching solutions will be presented, that can provably improve the users' satisfaction and also reduce the network operating expenditures. We will conclude with key open questions regarding the caching and delivery of (video) content in these SDN-enabled wireless systems.


George Iosifidis is the Ussher Assistant Professor in Future Networks, Trinity College Dublin, the University of Dublin; a Funded Investigator at the SFI research centre CONNECT, Ireland; and an Associate Research Scientist with the Department of Electrical Engineering, Yale University, USA. He obtained his M.Sc. and Ph.D. degrees from the Department of Electrical and Computer Engineering, University of Thessaly, Greece, in 2007 and 2012, respectively. He holds an engineering Diploma in avionics and quality control. He worked as a Post-doctoral researcher at CERTH, Greece, and Yale university, for 2 years respectively, and as an aircraft engineer from 2001 to 2012. His research interests lie in the area of network optimization and network economics with applications to wireless networks. He has received the Best Paper Award in WiOpt 2013 and served as the Co-Chair of the ACM CoNEXT 2014 Student Workshop.
