Dissertation -Departamento de Informática, Pontifícia Universidade Católica do Rio de Janeiro.To achieve high scalability in distributed simulations is necessary to avoid communication bottlenecks. Messages between machines are necessary when an agent kept in a specific computer needs to interact with elements kept in another computer. This work presents an approach to dynamically partitioning a distributed simulation keeping each agent in the same network node where are the elements more accessed by it, reducing the communication cost between the network computers. To reach this objective, we are using the concept of interest management, which aims to provide to an agent only the smallest set of information necessary to allow it to interact with the environment in a coherent way. To illustrate the proposed solution was developed a case study comprehending a distributed simulation representing an oil spill scenario.
