    This paper describes a quality of service (QoS) provisioning scheme for IEEE 802.11 infrastructure based networks. Our proposal, called "slide and translate" (SNT), adapts EDCF contention parameters to suit the varying traffic load in a basic service set (BSS). The aim of the SNT algorithm is to: 1) protect high priority access categories (AC) from increasing background traffic; and 2) maintain ef... View full abstract»

    A core problem for distributed systems is efficient location of the nodes which store desired data items. This paper presents a consistent hashing-based catalog service engine, which can map keys onto the nodes in an identifier ring with load balance, and the improved algorithm is given to speed the key location. Utilizing this model with data summary can process queries for XML repositories effic... View full abstract»

    This paper presents a multimedia transport service based on distributed QoS (quality of service) management mechanisms acting along the communication path. The distribution model is supported by a simple active networking paradigm for IP based networks. On demand QoS adaptation is performed by transport agents located along the network path when required by receivers. The transport service provide... View full abstract»

    Continuous media transmissions on collaborative platforms distributed over Internet introduces constraints like heterogeneity and security. It is why we propose a version of our cooperative application framework (CAliF), called CAliF Web, based on Web-services. SOAP has been chosen to transmit discrete flows because of its total integration to Web technologies. Nevertheless, performances of this m... View full abstract»

    Many papers have been written about quality of service integration in active nodes. However, all these works focused only on QoS vertical integration: QoS at active application layer, at active network layer or at "classical" network layer. We have already presented in (Fuin et al., 2004) our approach of QoS vertical integration at active network layer. In this paper, we focus on QoS horizontal in... View full abstract»
