Accelerated Entry Point Search Algorithm for Real Time Ray Tracing
(2009)Traversing an acceleration data structure, such as the Bounding Volume Hierarchy or kD-tree, takes a significant amount of the total time to render a frame in real-time ray tracing. We present a two phase algorithm based ... -
On Using Profiles to Create Self-Organizing Peer-To-Peer Networks
(IEEE, 2005)Searching and organization of peers are fundamental challenges in P2P networks. Unstructured networks, such as Gnutella, inefficiently use broadcast searches and random neighbors. Structured networks are similarly ... -
Decentralized Clustering in Pure P2P Overlay Networks Using Schelling's Model
(IEEE, 2007)Clustering involves arranging a P2P overlay network?s topology so that peers having certain characteristics are grouped together as neighbors. Clustering can be used to organize a P2P overlay network so that requests ... -
A Peer-to-Peer Reference Architecture
(IEEE, 2006)Peer-to-Peer (P2P) applications are extremely popular on the Internet because they allow users to share information in a decentralised manner. Internet users use file-sharing applications (e.g., BitTorrent, KaZaA) to ... -
A Framework for Developing Mobile, Context-aware Applications
(2004)The emergence of truly ubiquitous computing, enabled by the availability of mobile, heterogenous devices that supply context information, is currently hampered by the lack of programming support for the design and ... -
Using trust for secure collaboration in uncertain environments
(2003)The SECURE project investigates the design of security mechanisms for pervasive computing based on trust. It addresses how entities in unfamiliar pervasive computing environments can overcome initial suspicion to provide ... -
Understanding link quality in 802.11 mobile ad hoc networks
(2004)Mobile ad hoc wireless networks will extend the Internet into new territory, making Web services available ?anytime, anywhere.? This creates new markets in such areas as pervasive computing and traffic management.The ... -
Domain modelling for ubiquitous computing applications
(2007)Many Ubiquitous computing applications can be considered as planning and acting problems in environments characterised by uncertainty and partial observability. Such systems rely on sensor data for information about ... -
Chisel: A Policy-Driven, Context-Aware, Dynamic Adaptation Framework
(IEEE Computer Society, 2003)We argue that the software user, the developer, the designer and indeed the application logic itself all possess invaluable intelligence to gear how software should adapt itself to changing requirements and changing ... -
Filtering and scalability in the ECO distributed event model
(IEEE Computer Society, 2000)Event-based communication is useful in many application domains, ranging from small, centralised applications to large, distributed systems. Many different event models have been developed to address the requirements ... -
Dynamic Charging for Information Services
(Institution of Electrical Engineers, 1997)The last five years has seen an incredibly rapid growth in the number of subscribers to the Internet and in the number of organisations which now consider a presence on the world wide web as vital to their commercial ... -
An overview on legacy system migration
(IEEE, 1997)Legacy information systems typically form the backbone of the information flow within an organisation and are the main vehicle for consolidating information about the business. These systems also pose considerable problems ... -
Workflow - A Unifying technology for (Telecommunications) Operational Support Systems
(IEEE, 2000)A crucial issue facing Telecommunications Service Providers is the need to provide flexible, cost effective, management systems, which can rapidly adapt to changing customer requirements and inarket opportunities. A ... -
Managing User-centric Adaptive Services for Pervasive Computing
(IEEE Press, 2004)Pervasive computing environments need to exhibit highly adaptive behavior to meet the changing task requirements and operational context of visiting mobile users. However this must be balanced with the need of resource ... -
Policy Based Management for Internet Communities
(IEEE Press, 2004)Policy Based Management (PBM) is a research topic that has been driven by the tremendous complexity inherent in the administration and management of present-day networking and telecommunications systems and services. ... -
Intuitive Human Governance of Autonomic Pervasive Computing Environments
(IEEE, 2005)This paper proposes an intuitive configuration tool for autonomic pervasive computing systems. Specifically the paper presents a system for the inference of user task intentions from a variety of sensed information and ... -
Semantic Interoperability to support context in adaptive applications
(IEEE, 2008)The challenge of supporting Ubiquitous Computing is to assist the user by helping their applications make better decisions with better information. Smart spaces and other information sources can provide this information, ...
