A world model for ubiquitous computing environments is presented. It can be dynamically organized like a tree based on geographical containment, such as in a user-room-floor-build...
When ubiquitous computing devices access a contextawareness service, such as a location service, they need some assurance that the quality of the information received is trustwort...
A layered depth image (LDI) is a new popular representation and rendering method for objects with complex geometries. Similar to a 2D image, the LDI consists of an array of pixels...
— This paper addresses the problem of designing a power-aware Multiple Access Control (MAC) protocol for Multihop Wireless Networks (MHWN). The problem is formulated as a cross l...
In this paper we identify a common aim between ubiquitous computing and hypertext systems: the desire to present navigable, located and structured information. We propose that exi...
