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
