    Model-Driven Cloud Data Storage

    The increasing adoption of the cloud computing paradigm has motivated a redefinition of traditional software development methods. In particular, data storage management has received a great deal of attention, due to a growing interest in the challenges and opportunities associated to the NoSQL movement. However, appropriate selection, administration and use...

    Matrix Powers Algorithms for Trust Evaluation in PKI Architectures

    This paper deals with the evaluation of trust in public-key infrastructures. Different trust models have been proposed to interconnect the various PKI components in order to propagate the trust between them. In this paper, the authors provide a new polynomial algorithm using linear algebra to assess trust relationships in a...

    Wireless Sensor Network System Helping Navigation of the Visually Impaired

    Navigation aids for the pedestrians are considered new research challenges. The visually impaired are particularly concerned, because of their need to detect and avoid obstacles, as well as to orient themselves in unknown environments. In this paper, the authors discuss some existing projects in this domain and they propose a...

    Wireless Sensor Network Infrastructure : Construction and Evaluation

    Large area wireless sensor deployments rely on multi-hop communications. Efficient packet transmissions and virtual topologies, which structure sensor networks, are two main features for efficient energy management in wireless sensor networks. This paper aims to present a distributed and low-cost topology construction algorithm for wireless sensor networks, addressing the following...

    Secure Data Aggregation in Wireless Sensor Networks. Homomorphism Versus Watermarking Approach

    Wireless sensor networks are now in widespread use to monitor regions, detect events and acquire information. Since the deployed nodes are separated, they need to cooperatively communicate sensed data to the base station. Hence, transmissions are a very energy consuming operation. To reduce the amount of sending data, an aggregation...

    A Dynamic Clustering Construction for Wireless Sensor Networks

    Research in sensor networks has focused on development of energy efficient and secure infrastructures. In this paper, the authors introduce a new approach to organize sensor networks in clusters in order to reduce energy dissipation. Their contribution is a heuristic to define the number of clusters and also an efficient...

    Efficient and Robust Secure Aggregation of Encrypted Data in Sensor Networks

    Wireless sensor networks are now in widespread use to monitor regions, detect events and acquire information. To reduce the amount of sending data, an aggregation approach can be applied along the path from sensors to the sink. However, usually the carried information contains confidential data. Therefore, an end-to-end secure aggregation...

    Geometric and Signal Strength Dilution of Precision (DoP) Wi-Fi

    The democratization of wireless networks combined to the emergence of mobile devices increasingly autonomous and efficient lead to new services. Positioning services become overcrowded. Accuracy is the main quality criteria in positioning. But to better appreciate this one a coefficient is needed. In this paper the authors present Geometric and...

    EcnLD, ECN Loss Differentiation to Optimize the Performance of Transport Protocols on Wireless Networks

    One major yet unsolved problem in wired-cum-wireless networks is the classification of losses, which can be due either to wireless temporary interferences or to network congestion. The transport protocol response to losses has to be different for these two cases. If the transmission uses existing protocols like TCP, the losses...

    A Low Latency MAC Scheme for Event-Driven Wireless Sensor Networks

    In this paper, the authors present a low latency media access control scheme which they call LLMAC (Low Latency MAC) for event-driven Wireless Sensor Networks (WSN). In this kind of WSN, sensors do not regularly send data to the sink. They send a burst data only when there is an...
