Description
Summary:The search for improvement in the process of diffusion of information has led to many advances in access technologies. In initiatives for digital/social inclusion, this improvement is of utter importance, particularly in scenarios where the infrastructure becomes a barrier in communication. An alternative to improve communication and thus providing quality of service is to adjust the use of resources/bandwidth required by the applications. This paper presents an application-scheduling algorithm, based on fuzzy logic, to optimize the use of bandwidth and guarantee QoS for existing applications. Simulations were made from a built testbed for xDSL technology; results showed that the proposed scheduler is able to optimize the channel, guaranteeing minimum levels of QoS based on the particular needs and characteristics of each application.
