Fiber-wireless (FiWi) access mesh networks have been proposed as flexible and cost-effective solutions for future access networks. However, for FiWi access mesh networks to provide end-to-end QoS guarantees to its customers, efficient QoS routing schemes and scheduling policies become necessary. Here we provide a model, using repeated game theory, that creates ground for scheduling policies to be...
Humans tend to interact, to share information and establish relationships and naturally form groups based on interests. This fact motivate research on models, abstractions and mechanisms in order to enable more transparent and flexible interactions between users and group based collaborations. We propose a model that deals with dynamic group membership and combines multiple forms of communication...
Image annotation is hard to do in an automatic way. In this paper, we propose a framework for image annotation that combines the benefits of three paradigms: automatic annotation, human intervention and entertainment activities. We also describe our proposal inside this framework, the ASAA (application for semi-automatic annotation) interface, a new computer game for image tagging. The application...
