RESUMO

In the last decades, increasing interest has been observed in technologies related to wireless mobile communication environments. Great part of such interest follows the growth in the telecommunications industry, more specifically of cellular mobile telephony systems. Users are quickly absorbing these technologies and generating new necessities, such as the use of services of multimedia data, which demand quality assurance. In this context, one of the challenges is the efficient use of the limited frequency spectrum available, providing users quality services. This thesis proposes an architecture for the provision of end-to-end QoS in wireless mobile networks, taking into account inherent characteristics of these environments. To reach this purpose, modifications were proposed to the frameworks for QoS provisioning in generic processing and communication environments, aiming to fulfill the necessities brought by mobile networks, generating an adaptable architecture to offer QoS in environments that support mobile connections. In order to validate the proposal, an instantiation of frameworks for QoS provisioning in wireless mobile networks is described by means of a mobility scenario in which an infrastructure network of integrated services is simulated working over Mobile IP.
