This abstract describes a series of possible applications of the ultra wide band wireless technology in public transportation environment. Application scenarios for both the high data rate technology based on WiMedia and the low data rate technology based on impulse radio are presented, indicating the specific advantages provided by UWB in comparison to other narrow band wireless standards. The work...
In this paper, we present a disaster-scale mapping and energy-efficient alerting scheme that can be used in disaster monitoring environments that are prone to node failure and destruction due to the occurrence of disasters, and are generally deprived of GPS capabilities and or availability. The mapping scheme is able to provide a distributed mean of monitoring and reporting disaster's location which...
The objective of this invited talk is to present selected visions of ubiquitous computing and ambient communication based on the notion of the disappearing computer and to reflect on the resulting challenges for designing experiences in future smart environments. Our approach places the human at the centre of our design considerations and is based on exploiting the affordances of real objects by augmenting...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
