Mobile Computing and Mobile Cloud Computing are the areas where intensive research is observed. The “mobility” landscape (devices, technologies, apps, etc.) evolves so fast that deﬁnitions and taxonomies do not catch up with so dynamic changes and there is still an ambiguity in deﬁnitions and common understanding of basic ideas and models. This research focuses on Mobile Cloud understood as parallel and distributed system consisting of a collection of interconnected (and virtualized) mobile devices dynamically provisioned and presented as one uniﬁed computing resource. This paper focuses on the mobile green computing cloud applied for parallel and distributed computations and consisting of outdated, abandoned or no longer needed smartphones being able to set up a powerful computing cluster. Besides showing the general idea and background, an actual computing cluster is constructed and its scalability and efficiency is checked versus the results obtained from the virtualized set of smartphones. All the experiments are performed using a dedicated software framework constructed in order to leverage the nolonger-needed smartphones, creating a computing cloud.

Nowadays, urban computing has gained a lot of interest in regards to guiding the evolution of cities into intelligent environments. These environments can be appropriated for interactions between individuals that may ultimately affect and modify their behavior. These changes require new approaches that allow us to better understand how urban computing systems should be modeled. In this work, we present UrbanContext – a new model for designing urban computing platforms that applies the theory of roles to manage the individual’s context in urban environments. The theory of roles helps us understand the individual’s behavior within a social environment, allowing us to model urban computing systems capable of adapting to an individual’s states and needs. In order to optimize social interaction and offer secure services, Urban-Context collects data in urban atmospheres and classifies behavior according to the individual’s change of roles. Likewise, UrbanContext serves as a generic model to provide interoperability as well as facilitate design, implementation, and expansion of urban computing systems.

Assisted living applications are commonly understood as technical environment for disabled or elderly people providing the care in the user-specific range. We are going to present the data capture methodology and design of a home care system for medical-based surveillance and man-machine communication. The proposed system consists of the video-based subject positioning, monitoring of the heart and brain electrical activity and eye tracking. The multimodal data are automatically interpreted and translated to tokens representing subject's status or command. The circadian repetitive status time series (behavioral patterns) are a background for learning of the subject's habits and for automatic detection of unusual behavior or emergency. Due to mutual compatibility of methods and data redundancy, the use of unified status description vouches for high reliability of the recognition despite the use of simplified measurements methods. This surveillance system is designed for everyday use in home care, by disabled or elderly people.

A method of extending software applications by introducing elements of environmental context information is presented in the paper. The definition of context is based on the general context ontology. The information coming from the environment is transformed into certain execution conditions. As an algorithm of the transformation, a Petri net was used. It enables the application to properly react to certain events occurring in the environment. This is how “pervasive computing” applications are constructed.

Zaprezentowano kierunki rozwojowe obliczeń rozproszonych oraz ich wpływ na realizację nowego typu systemów informacyjnych. Systemy te są naturalnie wkomponowane w środowisko pracy użytkowników. Przedyskutowano metody ich implementacji z wykorzystaniem architektury SOA (dostępnych usług). Podano reprezentatywny przykład takiego systemu, tzn. tablicę interaktywną realizowaną w zespole badawczym.

Developing trends of distributed computing and their impact on creation new types of information-processing systems are presented. These kinds of systems are naturally embedded in user environments. Suitable implementation methods based on SOA architecture (available set of basic services) are discussed. An representative example of such a system called interactive wall designed by our team is given.
