Los nuevos servicios y aplicaciones disruptivas requieren la utilización de redes de comunicaciones de banda ancha. En el segmento de acceso, las redes de acceso ópticas pasivas (PON) se están consolidando como la mejor alternativa para este despliegue dado que las tecnologías de acceso tradicionales (cable coaxial, cobre) ya han dejado de ser capa...
Conference Paper
Agents are understood by definition as entities that interact with their environment and also with other agents. Thus, when two or more agents are able to work together in order to solve a common problem, they form a multi-agent system (MAS). MAS are systems that integrate a set of agents that interact, communicate and coordinate to achieve the est...
