Steps Towards Creating a Context-Aware Agent System
(2001-09-27)The ability to reason from context is crucial to human communication. It allows a large amount of implicit information to be conveyed with a small amount of explicit description. If the same kind of ability can be provided ... -
DReggie: Semantic Service Discovery for M-Commerce Applications
(2001-10-12)The emergence of mobile devices and wireless networks has created a new path in the field of e-commerce: “mcommerce”. Significant research is needed, in the field of service discovery, to support m-commerce applicatio ... -
An Agent-Based Approach to Ubiquitous Information Access
(2001-10-12)Ubiquitous information access from different mobile devices is a challenge to computer science researchers. Research in this areas has focused on eliminating different wireless link related problems like bandwidth, ... -
Transport Protocols in Wireless Networks
(IEEE, 2001-10-15)It is well-known that TCP performs poorly in a wireless environment. This paper presents an empirical performance analysis of TCP on Cellular Digital Packet Data (CDPD) and Bluetooth. This analysis brings out the ... -
Query Routing and Processing in Mobile Ad-Hoc Environments
(2001-11-12)In existing mobile information access systems, mobile devices are typically viewed as consumers of information, with information providers resident on the wired network. With the advent of short-range ad-hoc connectivity ... -
Gender in cross-cultural perspective : insights from Cameroonian women living in the U.S.
(2002)This research attempts to understand the perspectives of two Cameroonian women living in the U.S. The research focuses on the roles, expectations, and stereotypes of Cameroonian and American women and men. After interviewing, ... -
Towards Collaborative Spatial Decision Support in a Web-Based Environment
(IRMA, 2002)Spatial decision-making in a distributed environment involves access to data and models from heterogeneous sources and repositories to compose disparate services into a meaningful integration. This is especially true in ... -
Issues in Data Management for Pervasive Environments
(2002-01-12)A new vista is open for research in the area of data management in pervasive environments where mobile devices gather and exchange information from other devices based on their current context. Each device is both a data ... -
A Reactive Service Composition Architecture for Pervasive Computing Environments
(2002-03-12)Technological advances in semiconductor processing and design as well as wireless networking are leading us towards the vision of Pervasive Computing. We envision that in the (near) future, devices all around a person, ... -
Middleware for Mobile Information Systems
(2002-03-12)Mobile information access involves retrieving information from wired service providers. Often there are situations where the information is not available from a single service provider bug can be obtained by combining ... -
Design and Evaluation of a Common Access Point for Bluetooth, 802.11 and Wired LANs
(2002-06-24)Devices using wireless technologies like Bluetooth and 802.11b will be ubiquitous in the near future. The technologies supporting these devices will need to co-exist in order to support smooth exchange of information. We ... -
Enabling Peer-to-Peer Resource Discovery in Agent Environment
(2002-07-07)Negotiation, co-operation and collaboration between muti-agents systems is the key to success in the agent world. An agent that is capable of these actions can offer them as services. the main challenge lies in discovering ... -
Semantic Resolution for E-commerce
(ACM, 2002-07-15)We describe a research project on resolving semantic differences for multi-agent systems (MAS) in electronic commerce. The approach can be characterized as follows: (1) agents in a MAS may have their own specific ... -
Beyond Distributed AI, Agent Teamwork in Ubiquitous Computing
(2002-07-16)Agent teamwork has been widely studied in the fields of Distributed AI. Much success has been achieved in defining agent teamwork theory to explain how agents should act together as a team and in developing programming ... -
MagicWeaver: An Agent-Based Simulation Framework for Wireless Sensor Networks
(2002-08-01)Distributed sensor networks have been the focus of considerable research during the past few years. Current research on wireless sensor networks can involve a number of issues, including hardware constraints, communication ... -
Vigil: Providing Trust for Enhanced Security in Pervasive Systems
(2002-08-12)Computing today is moving away from the desktop, becoming diffused into our surroundings and onto our personal digital devices. Moreover, ad-hoc networks such as Bluetooth provide for spontaneous connectivity between ... -
Information agents for mobile and embedded devices
(World Scientific Publishing Co Pte Ltd, 2002-09-01)The pervasive computing environments of the near future will involve the interactions, coordination and cooperation of numerous, casually accessible, and often invisible computing devices. These devices, whether carried ... -
