There is currently lot of work in Ambient Intelligence particularly in context awareness. Context awareness enables service discovery and adaptation of computing devices for Ambient Intelligence application. In the same time, there is a common agreement of the fact that context aware systems should be responsive to Multi agents, assisting a large number of people, covering a large number of devices,...
To realize smart home services, several context-aware applications should be deployed which adapt their behavior depend on context information of home occupants. For context-aware service, context providing, processing, reasoning, delivery and designing context-aware applications are complex tasks. In this paper, we present a context-aware middleware which provides above tasks and supports context...
To support rapid prototype development and integration of emerging smart home applications, we discuss a flexible and modular middleware framework implementation for home gateway system. The suggested implementation allows for uniting all heterogeneous networked resources with the gateway and publishes semantic enhancement of the cues being triggered by network resources to be processed in a meaningful...
Smart applications rely on middleware abstraction to interact with the environment in order to collect relevant information for context determination. Among the forms of representing context in smart spaces, ontologies have been used because of the possibility of sharing, reusing and also modelling the semantics of context, independent of programming language, operational system and/or middleware...
The XML DOM (Document Object Model) provides a logical view of the in-memory structure. It represents the metadata that has a hierarchical treelike structure consisting of nodes. There are several benefits of implementing the XML DOM as a home management server. First of all, the process time decreases by three times in average sense than using general database. Secondly, it would make to meet with...
With the emergence of ubiquitous era, it has become increasingly important for context-aware computing which takes full advantage of proactive services to support user environment. Many kinds of studies on context-aware services for supporting user-centric services have been performed. Recently related researches are concentrated on only service acquisition. Therefore most studies of them have not...
In the pervasive computing paradigm, there is a strong demand towards user-centric services based on the context and service management. For implementing the user-centric services recent researches on the service-oriented system is focused on the context recognition, analysis and reasoning. Furthermore, the service-oriented systems also need to manage the structural and hierarchical context model...
We present in this paper the results of testing the OCP2 middleware. OCP2 is an efficient middleware for context information management with reasoning capabilities based on semantic web, which offers different ways to express real world behavior (such as rules or patterns), modeling them on top of the ontology. More specifically, we focus on its performance and scalability. Performance has always...
This paper proposes a semantic pattern-based context-aware (SPBCA) middleware for ubiquitous computing environments. It introduces two concepts, the ontology and the proactive conversion, to solve the heterogeneity issues existing in the interaction process in the ubiquitous computing environments. Furthermore, it can support user-centric context awareness not only by automatic reactive information...
This paper introduces a tele-management system as a part of SmartUM which is a ubiquitous cloud middleware for ubiquitous city (u-city). The cloud computing platform allows users to control remote devices. The users get data from a various kinds of remote sensors and scene images about the place of sensors from remote video cameras and control remote devices seeing the scene images of the remote place...
Current information service systems are built to serve all users, independent of the special needs of any individual user in different situations. Personalized information service aims at improving the retrieval process by taking into account the particular interests of individual users. However, not all user preferences are relevant in all situations, and they should be understood in context with...
As elders age, performing everyday tasks can be filled with risks that threaten their health and independence. We present a context-aware component based on agents that enables developers to build Ambient Intelligence Systems for supporting the independent living of elders. This component uses the ELDeR ontology that we propose to model the context information inherent to the elder's daily activities...
