Mobile Agents: Application to services in mobile computing and architectural improvements

Abstract. Mobile and more generally distributed computing are two basic re-search areas of Information Technology since they find many applications in our daily life, mainly due to the rapidly increasing growth of technologies of mobile networks and the Internet. The penetration of these technologies in our contemporary life has by far changed the way we work, communicate, seek in-formation and organize our lives. In the present thesis are presented subjects that concern these two research areas. Main characteristic of this thesis is the adoption of Mobile Agents (MA) technology and their combination with other technologies and methodologies (such as the Semantic Web, the Case Based Reasoning methodology and same principles from Game Theory) into the in-troduced frameworks, so that lend to better results concerning the already used technologies. This thesis focuses in two basic axes, a. Modeling, description and comparative evaluation of application frameworks that allow, with trans-parent means, service selection and provision to mobile users, in mobile net-works with the use of MA and b. Modeling, description and evaluation of a framework for resource management in MA networks
