co-located with WiOpt 2017
Paris, France, May 15, 2017

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:

- Scaling laws for the capacity of wireless networks equipped with caches
- Caching architectures and cache replacement policies for wireless networks
- Optimal content/cache placement: polynomial-time approximation algorithms,
minimum latency problem, minimum network traffic problem (both static & dynamic variations)
- Joint replication and delivery techniques: replacement policies, dynamic routing policies
- Proactive caching: recommendation models, prefetching, scheduling
- Estimation of content popularity: machine learning approaches, dynamic content popularity
models, measurement-based popularity estimation, prediction of future popularity and
popularity trends
- Exploitation of the time aspect: caching viral files, user mobility, non-stationary models
- Interface of caching techniques with communications techniques, including scheduling,
routing, multicasting, femto-caching, and MIMO communications
- Network coding techniques: coded caching, distributed storage
- Network economic aspects of caching: where to cache? Storage vs Bandwidth tradeoff,
incentives, game theoretic models
- Practical aspects of content caching and delivery in wireless networks including control
information overhead minimization, efficient protocols, standardization, and issues such
as tunnelling and encrypted content
- Lessons learnt: what known techniques from Content Delivery Networks teach us
- Energy saving through caching
- Caching for Information Centric Networks

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. 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.

**SUBMISSION GUIDELINES

A submission must be no greater than 6 pages in length including all figures, tables, references,
appendices, etc., and must be a PDF file of less than 10MB in size. The review process is single-blind.
Follow the same formatting guidelines as the WiOpt symposium. See the Information for Authors page
(http://wiopt.telecom-paristech.fr/authorinfo.html). Submissions that deviate from these guidelines
will be rejected without consideration.
Use the paper submission site (https://edas.info/newPaper.php?c=22972) to submit your paper
by 23:59 pm Central European Time (CET), February 3, 2017.
