The SHELL project aims at implementing state of art technologies in the domains of Wireless Sensor Networks, Ambient Intelligence, Context Awareness, Automated Learning, in order to design a new concept for assisting people affected by mental diseases or living alone. The goal to achieve is a modular device kit system, easy to deploy and to use, which will be able to learn to peculiar habits of the...
Online/offline signatures are used in many applications where the signer must respond quickly once the message to be signed is presented. The idea is to split the signing process into two phases: The first phase is performed offline before the message to be signed is available and the second phase is performed online after the message to be signed is provided. Recently, an identity-based online/offline...
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...
Reverse Auction is one of the best-known market-based mechanisms for allocation of delay-constrained tasks to distributed sensor nodes in wireless sensor network as a typical application in pervasive computing. However, costly message exchanges with enormous overheads among resource-constrained sensor nodes for decision making are required. In this paper, a novel energy/delay-efficient distributed...
Considerable research has been performed in applying run-time reconfigurable component models to Wireless Sensor Networks. The ability to dynamically deploy or update software components has clear advantages in sensor network deployments, which are typically large in scale and expected to operate for long periods in dynamic environments. Realizing distributed reconfiguration in Wireless Sensor Networks...
Pervasive grid computing platforms are composed of a variety of fixed and mobile nodes, interconnected through multiple wireless and wired network technologies. Pervasive grid Applications must adapt themselves to the state of their surrounding environment which includes environmental data (e.g. collected from sensors) and the state of the used resources (e.g. network or node states). Adaptation is...
Monitoring of the sub-sea environment requires advanced sensor networks with both stationary and mobile nodes on the surface and underwater, each node playing a different role. The combination of mobile and stationary nodes, the loss of nodes due to harsh conditions, the difficult conditions for wireless sub-sea communication and the need for nodes to collaborate are all factors that require new approaches...
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.
