Recently, mobile computing and wireless communication technologies made so much progress that we can finally acknowledge the emergence of the mobile/ubiquitous computing paradigm we anticipated. A new generation of mobile devices (such as smartphones, handheld GPS, laptops, tablets, etc.) will probably lead revolutionary changes in the information society. These devices benefit from an amazing number of sensors, communication and networking capabilities. Their interconnection results in huge heterogeneous and distributed systems and we can already forecast that this will lead to revolutionary applications, services and usages. Among other specific features, what makes mobile and ubiquitous systems different and interesting from a research viewpoint is :

• the mobility of users, applications and devices,
• how they produce and handle geo-localized information,
• the heterogeneity among the nodes and the services,
• their intrinsic need of adaptation to changes in their execution environment,
• their limited energy/computing/storage/communication resources,
• their need for cooperation and intermittent connection to the Internet,
• the potential impact, as personal devices that travel with their user and carry personal information, that the devices and their applications may have on privacy.

It is still unclear today whether mobiquitous solutions will be able to achieve the resilience levels necessary for user transparency and acceptance. What seems obvious is that they will require, at least, but not only:

• New types of dependability mechanisms to cope with the intrinsic dynamics of mobile systems,
• New approaches to evolvable fault tolerance and security in order to adjust resilience features according to variations in execution environments, system requirements and/or availability of resources,
• New management strategies for adaptation ensuring acceptable levels of performance, energy consumption, trustworthiness, privacy and cost.

Such considerations are of prime importance in the context of emerging mobile devices and applications such as those used in smart urban transportation systems, body area systems, ambient assisted living solutions, environmental monitoring products, and vehicular ad hoc networks. Making such a complex ecosystems of devices and services resilient is a first challenge, but being able to assess the resilience level and capacity of adaptation of resulting solutions is also of utmost importance. The ambition and mission of ARMOR is to put on the foreground all above issues and provide a forum of discussion to interested industrials and researchers.
