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, ... -
Towards Policy Decomposition for Autonomic Systems Governance by Applying Biologically Inspired Techniques
(IEEE, 2008)Policy-based management systems use declarative rules to govern their operation whilst satisfying the goals of the system. One of the fundamental issues in policy engineering remains the inability to automatically ... -
OCCS: Enabling the Dynamic Discovery, Harvesting and Delivery of Educational Content from Open Corpus Sources
(2008)The World Wide Web (WWW) provides access to a vast array of educational content, a great deal of which is ideal for incorporation into eLearning experiences. However sourcing, harvesting and incorporating appropriate ... -
The Butterfly methodology: a Gateway-free approach for migrating legacy information systems
(IEEE, 1997)The problems posed by mission-critical legacy systems - e.g., brittleness, inflexibility, isolation, nonextensibility, lack of openness - are well known, but practical solutions have been slow to emerge. Generally, o ... -
Realising Adaptive Web Services through Automated Policy Refinement
(IEEE, 2007)Traditionally policy based management systems have relied on 'engineered' policy refinement to decompose high level policies down to low level policies for implementation 111121. Such management systems typically rely ... -
Service Oriented eLearning Platforms: From Monolithic Systems to Flexible Services
(2007)The learning management system (LMS) has dominated Internet-based education for the past two decades. However, the traditional LMS is failing to keep pace with advances in Internet technologies and social interactions ... -
Understanding as We Roam
(2007)Increasingly, the problem for roaming users isn?t discovering local Web services or local context information or even getting their applications to interoperate with them at a syntactic level, but rather achieving ...
