The experience of ubiquitous and seamless access to heterogeneous mobile communication networks is one of the core issues of today's research. One important issue is the reliable detection of spectrum holes. in this paper, we address three important spectrum holes detection algorithms in cognitive wireless networks: MTM-SVD based spectrum holes detection algorithm, Kalman filtering Predictor and Particle...
The objective of the work is to propose a context based formal language model of fault tolerant public transport system in pervasive environment. The system is modeled on the basis of context sensitiveness built inside the system to assist the decision making not only to identify the failed components but also to determine the alternate solutions to tolerate the faults when need arises. The fault...
Over the past 20 years, a lot of effort has gone into making the vision of ubiquitous computing a reality. A major focus of this effort has been on the understanding of human activity as input to enable the design and implementation of context-aware applications. Context-awareness is a vital enabling technology for ubiquitous virtual reality applications. However, it is only recently that we have...
Computing technology is radically changing the manner in which we work and communicate with computers. ubiquitous virtual reality (U-VR) has been researched in order to apply the concept of virtual reality and its technology into ubiquitous computing. In this paper, we analyze past research on ubiquitous virtual reality and find future research direction.
In order to provide users with intelligent services, ubiquitous computing needs to make user situation analysis in consideration of users' mobility. Thus, this paper defines context structure for recognizing dynamic changes in users' environment and proposes a model of multi-agent for processing users' context. The proposed context structure distinguishes between dynamic and static contexts according...
