Privacy sensitive environment re-decomposition for junction tree agent organization construction

A number of frameworks for decentralized probabilistic reasoning, constraint reasoning, and decision theoretic reasoning assume a junction tree agent organization (JT-org). A natural decomposition of agent environment may not admit a JT-org. Hence, JT-org construction involves three related tasks: (1) Recognize whether a JT-org exists for a given environment decomposition. (2) When JT-orgs exist, construct one. (3) When no JT-org exists, revise the environment decomposition so that one exists and then construct it. Task 3 requires re-decomposition of the environment. However, re-decomposition incurs loss of JT-org linked privacy, including agent privacy, topology privacy, privacy on private variables, and privacy on shared variables. We propose a novel algorithm suite Distributed Agent Environment Re-decomposition (DAER) that accomplishes all three tasks distributively. For Tasks 1 and 2, DAER incurs no loss of JT-org linked privacy. For Task 3, it incurs significantly less privacy loss than existing JT-org construction methods. Performance of DAER is formally analyzed and empirically evaluated.

Distributed agent environment: application and performance

A mobile environment is characterized by low communication bandwidth and poor network connectivity. Accessing web documents in a mobile environment is thus both inefficient and ineffective. To combat for the low bandwidth problem, we employ the multi-resolution transmission and browsing mechanism for web documents, in which a web document is partitioned into multiple units, to enable a mobile client to explore the more content-bearing portion earlier. To combat for the poor network connectivity problem, we utilize a mobile agent model in the distributed agent environment (DAE). A mobile agent has the capability of migrating to a base station that is currently serving a mobile client, establishing a virtual connection to the client. The agent, acting on behalf of the client, travels along the wired network to carry out its tasks and collect results, returning to the client at the end of its itinerary. We have implemented the DAE architecture, which supports mobile agent in a mobile environment, and demonstrated its usefulness in supporting our multi-resolution mechanism. We have also conducted experimental study, comparing performance between conventional mobile client/server model and different mobile agent models in accessing a database server through both wireless and wired networks.

Management Issues of a Mobile Agent-Based ServiceEnvironment

This paper introduces the concepts of a service management system for mobile agent-based services. In contrast to several other approaches in which agent-based applications are used to handle “traditional” network or service management aspects, this paper describes a way to manage the distributed agent environment itself. The proposed approach was designed and developed by using OSI Systems Management concepts as a starting point, which are modified and adjusted in order to fulfill the new requirements associated with the mobile agent paradigm. However, this paper does not cover integration or co-existence of the introduced agent management system (AMS) and traditional OSI management systems. Instead, the entire AMS environment is based on mobile agent technology. At present, this approach is validated in the context of the European research project Mobile Agent Environments in Intelligent Networks (MARINE).

CyberCut: A World Wide Web based design-to-fabrication tool

Abstract For some time there has been an expectation that a “mechanical MOSIS” system will soon become available to mechanical designers for the rapid manufacture of functional prototypes. Recent advances in client-server interaction, automated process planning, and rapid manufacturing services now make it possible to provide a World Wide Web based, seamless CAD/CAPP/CAM system. Currently, the following services are provided via the Internet: (1) a design-for-manufacture CAD interface, written in Java™, (2) a choice between two CAPP systems, and (3) access to an open architecture machine tool for fabrication of mechanical parts. Together, these modules comprise CyberCut, a mechanical design and manufacturing service. CyberCut is the extension of an already proven Integrated Manufacturing and Design Environment (IMADE) into a distributed agent environment. It will provide users access to a rapid prototyping service in a variety of materials, with the ±0.002 in. tolerances made possible by typical CNC machining.
