The 14th Workshop on Challenged Networks (CHANTS 2019)


colocated with ACM Mobicom 2019,

the 25th Annual International Conference on Mobile Computing and Networking

Oct 21-25, Los Cabos, Mexico


Scope and Overview

Challenged networks comprise those situations where communication is desired, but traditional Internet architectures fail to provide it effectively. Such networks may be characterized by intermittent connectivity, a heterogeneous mix of nodes, frequent nodal churn, and widely varying network conditions. The applications of challenged networks range from time-critical communications such as for disaster relief to delay-tolerant transmission in poorly connected regions or where censorship should be counteracted. However, challenged networking has also found many applications in everyday settings, for which they were not initially conceived, such as opportunistic networking supporting data-centric communications, traffic offloading from cellular networks, mobile cloud/edge computing, opportunistic and participatory sensing as well as challenged IoT.


CHANTS builds on the success of the thirteen previous CHANTS workshops and WDTN 2005, and aims to stimulate research on the most novel topics of challenged networking research. This year’s edition encourages submission of theoretical and experimental work (including studies of real deployment), with a primary interest in new directions of challenged networking in concrete application scenarios and demonstrators in areas such as autonomous driving, underwater robots, emergency response operations, underground mining, interplanetary missions, polar research and unmanned aerial vehicles. The workshop seeks original work presented in the form of research papers describing new research approaches and results, as well as demo and poster submissions. Highly disruptive work-in-progress and position papers are also welcome, provided they focus on particularly innovative solutions or applications for challenged networks. All papers shall be forward-looking, describe their relationship to existing work, and shall argue their impact and implications for ongoing or future research.


Topics of interest include, but are not limited to:

    Delay/disruption-tolerant networks (DTNs), opportunistic communication and computing

    Modeling and analysis of challenged networks and protocols for challenged networks

    Communication systems and networks for underground mining

    Underwater communication systems and networks

    Security/trust/privacy concerns and solutions in challenged networks

    Networking in polar regions

    Millimeter Wave Networking

    Challenged networking techniques for mobile cloud computing and mobile data offloading

    Challenged networking techniques for participatory and opportunistic sensing

    Challenged networking in the Internet of Things and in Cyber-Physical Systems

    Energy-efficient communication in challenged networks

    User behavior modeling and Quality of Service provisioning in challenged networks

    Space-terrestrial networks, lunar networks as well as interplanetary networks

    Information-centric and content-centric networking in challenged networks

    Real-world mobility trace collection, analysis, and modeling for challenged environments

    Network coding in challenged networks

    Real deployment and case studies in various stages of use

    Configuration, management, and monitoring of challenged networks

    Disrupted scenarios for challenged networks (e.g., disaster relief and emergency management)

    User Interfaces and interactive applications optimized for Challenged Networks

    Test and simulation tools for evaluating challenged network systems

Paper Format and Submission Instructions


General Paper Format

Submitted papers must be no longer than 6 pages, and should adhere to the standard ACM conference proceedings format.  All submissions must be written in English. Authors must register the abstract 1 week prior to the full paper submission.


Demo/Poster Format

Demo and poster proposals (to be published as part of the proceedings) must not be longer than 2 pages, for demos plus 1 page description of the precise setup and requirements (the 1-page setup description will not be published in the proceedings).



Reviews will be single-blinded. Papers should neither have been published elsewhere nor being currently under review by another conference or journal.


Editorial Follow-Ups

Extended versions of the selected workshop papers will be considered for possible fast track publication in well-known journals, e.g., Computer Communications (Elsevier) or the ACM GetMobile.
