Research

Below is a brief description of my current and previous research. It is not supposed to be a very complete description. The idea is just to say in one or two paragraphs what I am working on now and what I have worked on before.

Currently

Currently I am interested in studying sensor networks. More specifically, I am interested in developing middleware for sensor networking. To reach such goals, I have been getting familiar with sensor networks, MAC and routing layer protocols and the possible ways that middleware could interact with such protocols to provide better performance and energy savings to the applications. At the moment, I am working on a routing protocol for sensor networks data aggregation. My advisor in this research towards a PhD is Amy Murphy.

Previously

Before coming to the University of Trento, I was working in a project developing middleware for peer-to-peer based games. The idea was to try to minimize server load in multiplayer games, especially massive multiplayer games. To do that we developed an interest management system, so that only the peers that are interested in messages get to receive them. For instance, only players that can see each other in the virtual world should communicate. We accomplished that by dividing the virtual world of the game into objects called "smallworlds" that players can subscribe and unsubscribe according to their interests. Also, within a smallworld we also proposed a scheme for sending messages at different rates according to the virtual distance between objects (i.e. avatars) in the game. On this project I worked with Sergio Imperatriz, Rafael Castro, Ricardo Anido and Edson Cáceres.

Before that, I worked with methodologies for performance analysis of parallel (MPI-based) systems during my MSc. The idea was to develop new forms of visualizing parallel programs execution to help program developers to find bottlenecks and inefficiencies in their programs. My MSc advisor was Professor Ricardo Anido.

As an undergraduate I worked a little with multi-agent systems. We proposed a generic multi-agent system back then. At the time I worked with Eduardo Brião and our advisor for this project was Professor Silvia Botelho.
