Ninth ACM MobiCom Workshop on Challenged Networks


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, nodal churn, and widely varying network conditions. Traditional examples of challenged networks include inter-planetary networks, sensor and wildlife monitoring networks, underwater networks, rural and remote areas, and military battlefields. Recently, challenged networking has also found 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 computing, opportunistic and participatory sensing. Inter-disciplinary approaches to challenged networking protocols are also successfully explored, exploiting, for example, findings in the area of social networking. The availability of enabling technologies in mobile devices, such as WiFi direct in Android and D2D communication in latest LTE releases, will further push towards practical developments of challenged networking solutions.

This workshop builds on the success of the eight previous CHANTS workshops, and WDTN 2005, to stimulate research on the most novel and challenging topics of challenged network research. CHANTS provides an ideal venue for researchers and engineers to present cutting-edge work and results, as research papers or demos, in the following topics:

  • Delay/disruption-tolerant networks (DTNs)
  • Opportunistic communication and computing
  • Architecture, design, and implementation of communication systems for challenged networks
  • Modeling, analysis and characterization of challenged networks and protocols
  • Network coding in challenged networks
  • Information Centric and Content-Centric Networking in challenged networks
  • Security/trust/privacy concerns and solutions in challenged networks
  • Case studies involving real challenged network solutions in various stages of development or use
  • Applications of challenged networks in disrupted scenarios (e.g. disaster relief and emergency management) and in daily use (e.g., vehicular networks, mobile social networking, censorship evasion, crowdsourcing, sensor networks)
  • Green and energy-efficient communication using challenged networks
  • Real-world mobility trace collection, analysis, and modeling for challenged environments
  • Network science methods for challenged networks
  • Mobile data offloading via challenged networks
  • Test and simulation tools for evaluating challenged network systems
  • Configuration, management, and monitoring of challenged networks
  • Challenged networking techniques for mobile cloud
  • Challenged networking techniques for participatory and opportunistic sensing

Selected papers will be forward-looking, will describe their relationship to existing work, and will have impact and implications for ongoing or future research. We aim to have a highly interactive workshop, also including demos, which have been an integral part of CHANTS. Paper authors who can also run a demo of their work will be encouraged to do so. In exceptional cases, where live demos are simply not practical to present, poster or video presentations of practical results are acceptable. For more information, please check out other sections of this website or write to the workshop co-chairs at chants2014[at]iit[dot]cnr[dot]it.

Full paper submission guidelines

Papers should neither have been published elsewhere nor being currently under review by another conference or journal. All submitted papers will be carefully evaluated based on their originality, significance, technical soundness, and clarity of expression. Submissions must be in English, no longer than 6 pages with 10 point font and in PDF format, and use the ACM templates. All fonts must be embedded within the PDF and be Type 1 (scalable).

Papers will be reviewed single blind.

Demo proposals submission guidelines

Technical demonstrations showing innovative and original practical solutions in the above mentioned topics are solicited, showing working prototypes stimulating discussion among the attendees. Demo proposals (to be published as part of the proceedings) must not be longer than 3 pages plus 1 page description of the precise setup and requirements (the 1-page setup description will not be published in the proceedings). Manuscripts should be submitted following the exact same format as for full papers, except for the page limit.

Editorial follow-ups

Extended versions of the selected workshop papers will be considered for possible fast track publication on the Computer Communications Journal (Elsevier), in a special section on Challenged Networks.
