I enjoy making things. Here are a selection of projects that I have worked on over the years.
In order to improve the communication of Wireless Sensor Networks (WSNs), in an environment where the transmission quality is constantly being modified, we intend to develop mathematical models for the selection of cooperating nodes, where exact and approximate algorithms will be tested. Such models will be built in an approximate way, which allows the use of efficient algorithms to solve this problem. This was my postdoc project.
This project was developed during my Master and PhD studies. It is a framework for dynamic reconfiguration, value-based processor resource allocation in multi-modal or not real-time applications, under schedulability, energy consumption and temperature constraints. The framework is suitable for critical and soft real-time adaptive embedded systems which need guarantees of energy savings. The dynamic allocation is formulated as a discrete and continuous (convex and piecewise linear) optimization problem, for which efficient algorithms were tested. Although the discrete problem is NP-Hard, the others have efficient solution and numerical analysis and simulations have shown that the used algorithms and models achieves very good results, with low computational cost.
