During the last decades, mobile collaborative systems have become transversal applications that provide services not only to end-users but also to other systems like mobile social applications, context-aware recommender systems, crowd sourcing and participatory sensing applications, monitoring systems, and cyber physical systems. Providing services in mobile collaboration scenarios is complex, because the work context of each participant could be different, and also such a context is dynamic. Moreover, these solutions involve a wide range of heterogeneous devices that should interoperate to provide particular services (e.g., in the Internet of Things scenarios). Therefore, these new types of systems bring several challenges to system developers, particularly in terms of design, implementation, use, and evaluation. Although there have been important advances in these areas, many problems remain open.

We invite investigators to contribute original research articles as well as revised and extended works that help improve design, implementation, usage, and evaluation of mobile collaborative systems. Articles reporting case studies about adoption and usage of this technology are also welcome.

Potential topics include, but are not limited to:

• System architecture and patterns
• Transversal design aspects: privacy, security, and interoperability
• Framework and software applications
• Service-oriented mobile collaborative systems
• Systems evaluation
• Collaborative opportunistic networks
• Collaborative cyber physical systems
• Collaborative smart objects in the Internet of Things
• Context-aware collaborative systems.
• Case studies and experiences of use and adoption of mobile collaborative systems
