In this paper, we describe a case study in a large metropolis in which, based on data collected by digital sensors, we sought to understand mobility patterns of people using buses and how this can generate knowledge to suggest interventions to be applied incrementally to the transportation network in use. We first estimated an Origin-Destination matrix of bus users based on datasets about ticket validation...
In a Cloud Computing scenario, cloud services are accessed via Internet and typically there is a communication latency between the service provider and its clients. As a consequence, QoS parameters noticed by the clients (such as service response time) have different values depending on their location. In this paper, we propose the relative QoS (RQoS) concept, which defines that the quality of a service...
In ubiquitous environment context awareness approach plays a vital role in adaptability to users requirements. Context-sensitive systems meet specific requirements correctly, only if context information possesses the desired quality of context (QoC). Context data can be unreliable or inaccurate, thus undermining the potential of context-aware services. Some researches adopt a conflict resolution approach...
