Assembling the Planetary Computerponding lowering of the growth rates of the major suppliers of that global infrastructure. At the same time, several new “S-curves” are reaching their steep slope as ubiquitous computing begins to sweep the planet. Leading this will be a vast expansion in heterogeneous end-points to a new wireless i

A Probabilistic Room Location Service for Wireless Networked Environmentsfor a wireless network based on the IEEE 802.11 standard: inferring the location of a wireless client from signal quality measures. Similar work has been limited to prototype systems that rely on nearest-neighbor techniques to infer location. In this paper, we describe Nibble, a Wi-Fi location servi

Location Information Managmentsed spatial algorithm to integrate low-level location information, producing events that approximate closely to the needs of application programs. Preliminary experience indicates that the approach yields a very worthwhile reduction in the event traffic that must be handled by applications.

Low Cost Indoor Positioning Systemter and four ceiling mounted ultrasonic transmitters it provides coverage in a typical room in an area greater than 8m by 8m. As well as finding position within a room, it uses data encoded into the rf signal to determine the relevant web server for a building, and which floor and room the user is i

Making Everyday Life Easier Using Dense Sensor Networksg low-power multi-hop wireless networks. These networks foster a new class of ubiquitous computing applications called proactive computing. In proactive applications, computing occurs in the background without requiring human interaction; humans participate to access information or to modify control

ICrafter: A Service Framework for Ubiquitous Computing Environmentsctive of ICrafter is to let users flexibly interact with the services in their environment using a variety of modalities and input devices. We extend existing service frameworks in three ways. First, to offload services and user input devices, ICrafter provides infrastructure support for UI selectio

The configuration of the devices should be able to change frequently due to a highly dynamic, flexible and mobile nature of new work practices. This produces new requirements for the architecture of an appropriate software infrastructure. In this pape
