Smart city is rapidly gaining attention, and more than 400 sites are recognized all over the world, as of the year 2012. Smart city is regarded as an urban area where its social/public infrastructure is efficiently managed using the advanced technology such as ICT, environmental science. The original goal was to form a technology basis for low carbon society or efficient community in energy usage,...
Recommender systems are a subclass of information filtering system and are widely used in the ecommerce domain [13]. They filter huge amount of data to provide personalized recommendations on services or products to users. Most of the existing approaches to develop a recommender system do not take into account contextual information such as weather, day, time, distance and location to provide recommendations...
Sensor-rich Context Management Frameworks (CMF) for Ubiquitous Systems should be able to continuosly gather raw data from observed entities (e.g., people, surround enviroment) in order to characterize the current situation (i.e., context). However, the energy of sensors can end up, which reduce the ability of CMF for detecting the current situation, directly affecting the availability of context-aware...
Traditionally, context-aware applications are developed using one of the following approaches: each application communicates directly with sources of context information; applications are developed with the aid of reusable libraries for processing context information or applications have their own context models. These approaches not only require effort on the part of those who develop them, but also...
Community Context-attribute-centric Collaborative Information Environment (CCCIE) enables provision of services to users with same interests, by employing time awareness and demand-oriented perspective to transform one to one (1-1), one dimensional location based service paradigm to one to many (1-N), n-dimensional situation-aware community services. Unlike conventional Location Based Services (LBS)...
With the ubiquity of handheld devices people can now access information and conduct online transactions virtually anywhere and anytime. In such flexible but less reliable environment transaction management technology is believed to provide service reliability and data consistency. Existing models developed for mobile transactions mainly focus on variation of conventional commit procedures and give...
In context-aware computing, distributed information about entities, such as people, places and objects, is captured and made available to applications, which utilize this context. With contexts from multiple entities available, the degree of alikeness of those contexts poses an interesting piece of information. We have tackled the issue of contextual proximity by employing mechanisms known from location-based...
The context in intelligent domotic home (IDH) is very complicated. In this paper, in order to achieve the context-aware ability based on the DOG (domotic OSGi gateway) which is desiged for IDH, not only the information about the domotic devices and the building components, but also the characteristics and behaviors of users are concerned as the context. According to the context, a new context ontology...
