Introduction

With the popularity of smart phones and tablets, we are living in an increasingly mobile world. Third-party mobile applications such as Apple Siri, iCloud, and Yelp are rapidly growing everyday and greatly enrich our lives. The eco-system for mobile applications is vibrant and conducive to open innovation. Even one of the most popular mobile OS — Android operation system is open source. This allows many phone and tablet vendors to innovate on the hardware and firmware. Underpinning this mobile world, it is the cellular networks. Unfortunately, the cellular networks present a rather disheartening picture. They are closed, mostly proprietary, and constructed using closed monolithic equipments. The innovation is limited to a very small number of equipment vendors, not open to the general research community. As a result, cellular networks are prone to outages, dropped calls, performance problems, and hard to manage. The closed nature of cellular networks threatens to derail the mobile revolution or limit its true potential.

Research innovation in mobile cellular networks is hampered by the fact that most academic researchers have no access to cellular radios, source codes of cellular network equipments, cellular network management tools, and realistic network traces at scale. As a result, most wireless research is conducted using WiFi. We believe this situation much change. To effect change, this workshop brings network operators, and academic researchers together to address the problems. First, we would like academic researchers to understand operational aspects of cellular network. Second, we would like researchers from academia and industry to jointly identify the challenges, and propose future designs so that cellular networks can evolve to meet the growing challenges of a mobile world.

We encourage submission of both position papers and work-in-progress papers on previously unpublished work on cellular networks.

Topics

We solicit submissions on topics including, but not limited to, the following:

Operation aspects:

Radio resource allocation and usage profiling
Cellular network architecture characterization
Understanding and modeling cellular data traffic
Cellular network security

Challenges facing today’s cellular networks:

Cellular network management
Mobility
Energy efficiency
Spectrum shortage

Future cellular network design:

Architectures
Protocols
Algorithms
Security and privacy

Submission Instructions

Each submission must be a single PDF file no longer than six (6) pages in length (in two-column, 10-point format) including references, following the LaTeX style file. Papers should be submitted via the submission site. Papers must include the author name and affiliation for single-blind peer reviewing by the program committee. Authors of accepted papers are expected to present their papers at the workshop. Submissions must be original work not under review at any other workshop, conference, or journal.
