The increasing complexity and dynamics in which software systems are deployed calls for solutions to make such systems autonomic, i.e., capable of dynamically self-adapting their behavior in response to changing situations. To this end, proper models and software engineering tools are required to be available to support the design and development of(More)
The automatic and unobtrusive identification of user’s activities is one of the challenging goals of context-aware computing. This paper discusses and experimentally evaluates instance-based algorithms to infer user’s activities on the basis of data acquired from body-worn accelerometer sensors. We show that instance-based algorithms can classify simple and(More)
Software systems operating in open-ended and unpredictable environments have to become autonomic, i.e., capable of dynamically adapting their behavior in response to changing situations. To this end, key research issues include: (i) framing the schemes that can facilitate components (or ensembles of) to exhibit self-adaptive behaviors; (ii) identifying(More)
Distributed computing in large-size dynamic networks often requires the availability at each and every node of globally aggregated information about some overall properties of the network. In this context, traditional broadcasting solutions become inadequate as the number of participating nodes increases. Therefore, aggregation schemes inspired by the(More)
Smart phones and social networking tools allow to collect large-scale data about mobility habits of people. These data can support advanced forms of sharing, coordination and cooperation possibly able to reduce the overall demand for mobility. Our goal is to develop a recommender system to be integrated in smart phones, tablets, and in-vehicle platforms(More)
Future urban scenarios will be characterized by the close integration of ICT devices and humans. Citizens using their own capabilities integrated with ICT technologies could collaboratively constitute a large-scale socio-technical superorganism to support collective urban awareness and activities. This position paper, with the help of a representative case(More)
Modern handheld devices provided with localization capabilities could be used to automatically create a diary of user’s whereabouts, and use it as a complement of the user profile in many applications. In this paper we present the Whereabouts diary, an application/service to log the places visited by the user and to label them, in an automatic way, with(More)
This paper focuses on sensor networks as shared environmental infrastructures, and presents an approach to enable a sensor network to self-partition itself at pre-defined energy costs, into spatial regions of nodes characterized by similar patterns of sensed data. Such regions can then be used to aggregate data on a per-region basis and to enable multiple(More)
