    A Data Quality Methodology for Heterogeneous Data

    The authors present a Heterogenous Data Quality Methodology (HDQM) for Data Quality (DQ) assessment and improvement that considers all types of data managed in an organization, namely structured data represented in databases, semistructured data usually represented in XML, and unstructured data represented in documents. They also define a meta-model in...

    Self-Adaptive and Stateless Broadcast in Delay and Disruption Tolerant Networks

    In a delay and disruption tolerant network, or DTN, the network connectivity is intermittent, the radio links are poor and unstable, the nodes dynamically move and are sparsely distributed. These critical conditions have imposed a departure from the routing mechanisms viable in ad hoc networks and the adoption of a...

    Impact of Mobility on Epidemic Broadcast in DTNs

    The broadcast diffusion of messages in Delay Tolerant Networks (DTNs) is heavily dependent on the mobility of the nodes, since protocols must rely on contact opportunities among devices to diffuse data. This paper is the first effort of studying how the dynamics of nodes affect both the effectiveness of the...

    Handling Confidential Data on the Untrusted Cloud: An Agent-Based Approach

    Cloud computing allows shared computer and storage facilities to be used by a multitude of clients. While cloud management is centralized, the information resides in the cloud and information sharing can be implemented via off-the-shelf techniques for multiuser databases. Users, however, are very diffident for not having full control over...

    Distance Vector Routing for Public Transportation Vehicular Networks: Performance Evaluation on a Real Topology

    In this last two years an increasing number of scientists has devoted his attention to Vehicular Ad hoc NETworks (VANETs) as a special case of the more generic Mobile Ad hoc NETworks (MANETs). A public transportation network used as a VANET backbone may be a viable solution - under certain...

    Privacy Preservation Over Untrusted Mobile Networks

    The proliferation of mobile devices has given rise to novel user-centric applications and services. In current mobile systems, users gain access to remote servers over mobile network operators. These operators are typically assumed to be trusted and to manage the information they collect in a privacy-preserving way. Such information, however,...

    An Open Digest-Based Technique for Spam Detection

    A promising anti-spam technique consists in collecting users opinions that given email messages are spam and using this collective judgment to block message propagation to other users. To be effective, this strategy requires a way to identify similarity among email messages, even if the program used by the spammer to...
