O presente artigo pretende examinar a quantidade, qualidade e adequação dos comportamentos interactivos das educadoras em salas de creche, em actividades livres e estruturadas, investigando a sua relação com aspectos de estrutura destes contextos. Participaram neste estudo 30 responsáveis por salas de creche da Área Metropolitana do Porto (incluindo 5 auxiliares de acção educativa). Os comportamentos interactiv...

PRIVED: a Privacy Model for Heterogeneous Mobile Networks

We propose a network-oriented privacy model (PRIVED) composed by a well defined information model, using events, information sets and relationships to define the conceptual privacy relationships that can occur in the network. We propose formal rules and a network instantiation, using linkability and correlation as the main tools for network applicability. We also use the model to determine the best approaches tow...

FastM: Design and Evaluation of a Fast Mobility Mechanism for Wireless Mesh Net...

Although there is a large volume of work in the literature in terms of mobility approaches for Wireless Mesh Networks, usually these approaches introduce high latency in the handover process and do not support realtime services and applications. Moreover, mobility is decoupled from routing, which leads to inefficiency to both mobility and routing approaches with respect to mobility. In this paper we present a n...

Development of a Hybrid Simulation and Emulation Testbed For VANETs

In the area of Intelligent Transportation System traffic efficiency and safety for users have become very popular topics and have triggered extensive research in Vehicular Ad-Hoc Networks (VANETs). Traditional methods for reaserch and development like field testing and simulation have been used. But field testing is usually very expensive and simulation lacks accuracy in wireless environments. This article aims to ...

QoS in 4G scenarios using NSIS protocol

This paper presents qualaty of service mechanisms, based on NSIS ( Next Steps in Signaling) protocol. For that, it was implemented a testbed with NSIS running through IPv6. The network's QoS was mesured by the number of drops, for each flow (either QoS or Best Effort traffic), occurred inrouters. The first experiment shows the captured packets during a node association and request for QoS, namely a GIST sessio...
