This paper presents a location sensing system “Spreha” for sentient artefacts. Our approach towards context awareness is to use sensor augmented daily life objects for context sensing. Some of these artefacts are static in nature, like a cabinet, a bed, a refrigerator, etc. The basic idea in Spreha is to use these static artefacts as reference points for identifying the artefacts that are mobil...

Researchers have conducted various studies on applying wireless communication and ubiquitous computing technologies to education, so that the technologies can provide learners and educators with more active and adaptive support. This study proposes a Ubiquitous Performance-support System (UPSS) that can facilitate the seamless use of powerful new technologies in the school setting. In order to ...

Such a scenario introduces peculiar and challenging requirements in the development of distributed software systems. Because new agents (we use this term generically to indicate a distributed application's active components) can depart out of and arrive into the network at any time and roam across different environments, applications must be able to deal with such activity adaptively and indepe...

We have explored the design of an interactive, persuasive game to assist adults to improve dietary behaviors of kindergarten children. The persuasive game is played over a smart lunch tray. The smart lunch tray incorporates both context-awareness and interactive media persuasion, enabling the creation of a persuasive smart object.

This paper aims to address key concept of context awareness in the Internet of Things (IoT) domain by providing a model that proactively monitors behaviour of devices and services. This concept represents context into two types of information representation, namely set based and mark-up based ontology for the purpose of defining a context awareness model that accurately represent context in IoT...

High heterogeneity and dynamicity of pervasive computing environments introduces requirement of more flexible and functional access control policies. The notion of provisional actions has been defined previously to overcome the insufficient grant/denial response to an access request and has been incorporated in the provision-based access control model (PBAC). Based on PBAC, we propose a context...

The advances in IPTV (Internet Protocol Television) technology enable a new user-centric and interactive TV model, in which context-awareness is promising in making the user’s interaction with the TV dynamic and transparent. Our research interest is how to achieve user-centric personalized IPTV services applying context-awareness. In this paper, we present a solution for IPTV services personali...

Dempster-Shafer Evidence Theory(DST) enables multi-sensor data fusion, which makes it possible to infer the context. In this paper, we propose about how to use multi-sensor data fusion to infer context in the dynamic circumstances. Dynamic circumstance means a changing of the situation or the surrounding itself, and particularly signifies that there is a changeable factor in a specific environm...

Recently due to major changes in the structure of electricity industry and the rising costs of power generation, many countries have realized the potential and benefits of smart metering systems and demand response programs in balancing between the supply and the demand. DR mechanisms are capable of controlling the user energy consumption according to load conditions and providing effective ene...

Sensor Networks produce a large amount of data. According to the needs this data requires to be processed, delivered and accessed. This processed data when made available with the physical device location, user preferences, time constraints; generically called as context-awareness; is widely referred to as the core function for ubiquitous systems. To our best knowledge there is lack of analysis...
