JADE is a software framework to develop agent applications in compliance with the FIPA specifications for interoperable intelligent multi-agent systems. The goal is to simplify development while ensuring standard compliance through a comprehensive set of system services and agents. JADE can then be considered an agent middle-ware that implements an Agent Platform and a development framework. It...

An agent oriented management framework for pricing and controlling multimedia communications is presented as an on going research project. The framework model is described in terms of agent roles identified in multimedia domains. The agent components developed are based on CORBA technology allowing for object transparency. The use of intelligent, mobile and automated software provides a powerfu...

Mainly relying on Baars’ "Global Workspace" theory of consciousness, we identify computational correlates of consciousness and discuss their possible representation within a model of intelligent agents. We first review a particular agent implementation that is given by an abstract machine, and then identify the extensions that are required in order to accommodate the main aspects of consciousne...

Transmission Control Protocol (TCP) based web agents have has several deficiencies, such as performance degradation, head-of-line blocking, and unsupported mobility when applied to the mobile wireless environment. The Stream Control Transmission Protocol (SCTP) is a new transport protocol, which provides multistreaming and multi-homing features. Recent SCTP extensions with dynamic address recon...

Purpose – This paper aims to address some security issues in open systems such as service-oriented applications and grid computing. It proposes a security framework for these systems taking a trust viewpoint. The objective is to equip the entities in these systems with mechanisms allowing them to decide about trusting or not each other before starting transactions. Design/methodology/approach –...

Evolution of software challenges multi-agent systems to be adaptive and the adaptation capabilities should be provided at both the agent level and the system level. In this paper, we study the adaptation of multi-agent systems from the system level and describe a formal framework for multi-agent systems with adaptation capabilities. In the framework, agents are indirectly inter-connected via ro...

This paper focuses on the implementation of a novel semantic-based Conversational Agent (CA) framework. Traditional CAs interpret scripts consisting of structural patterns of sentences. User input is matched against such patterns and an associated response is sent as output. This traditional CA approach, which solely takes into account the structural form of a sentence, requires the scripter to...

When developing BDI agent-based systems, some design patterns such as incompatible intentions, multiple strategies, intention decomposition, etc. would be very useful in order to catch some desired agent behaviours. As BDI agent programmers, our desire would be to have a framework that natively support such common patterns. The PRACTIONIST framework provides a goal-oriented approach for develop...

As distributed multimedia applications become more widely diiused, systems for QoS management are increasingly essential. In this paper we will present an architecture for distributed QoS management based on software agents. A software agent is a software module often equipped with artiicial intelligence mechanism which is capable, autonomously or in cooperation with other agents, of solving a ...

Many agent-oriented software engineering methodologies have been proposed for software developing; however their application is still limited due to their lack of maturity. Evaluating the strengths and weaknesses of these methodologies plays an important role in improving them and in developing new stronger methodologies. This paper presents an evaluation framework for agent-oriented methodolog...
