Autonomous Agents make frequent interactions between people unrelated to each other possible. This is one of the most remarkable and attractive features of Electronic Commerce. Reputation management is therefore an important issue in order to make costly decisions in multi-agent systems. Different models have been proposed to ensure the convergence of the(More)
The Agent Reputation and Trust (ART) Testbed initiative was launched with the goal of establishing a testbed for agent reputationand trust-related technologies. This initiative has lead to the delivery of a flexible/modular prototype platform to the community. After two years and four successful competitions, several issues have arisen that require some(More)
Researches on Ambient Intelligent and Ubiquitous Computing in connection to wireless technologies have been increasing in the past years. Multiagent systems (MAS) are the ideal technology to support these applications. Nevertheless, only few models of MAS have been under evaluation. In this work, we evaluate a multi-agent architecture that may support the(More)
Trust modelling is a challenging issue due to the dynamic nature of distributed systems and the unreliability of self-interested agents. In this context, the Agent Reputation and Trust (ART) Testbed has been used to compare trust models in two Spanish competitions in 2006 and 2007 and several international competitions. In this paper we describe the model(More)
In this work, the application of fuzzy logic in surveillance systems based on cameras is analyzed. Three different fuzzy systems have been tested and compared with a crisp decision system. The first one has been developed using an expert knowledge, the second one was learned from recorded videos, and a third one is developed as a refinement taking into(More)
In this paper an agent-based simulation is developed in order to evaluate an Ambient Intelligence scenario based on agents. Many AmI applications are implemented through agents but they are not compared with any other existing alternative in order to evaluate the relative benefits of using them. The proposed simulation environment analyses such benefits(More)
