The ever increasing number of Internet-connected end-hosts calls for high-performance end-to-end networks, which in turn leads to an increase in the energy consumed by the networks. Our work deals with the energy-consumption issue in dedicated networks with bandwidth provisioning and in-advance reservations of network equipments for Bulk Data transfers.(More)
Admission control prevents certain flows from accessing a network with regard to the current utilization level of its resources with the ultimate goal of avoiding congestion and performance collapses, so that, accepted flows receive a sufficient level of Quality of Service (QoS). In this paper, we evaluate the performance of three measurement-based(More)
Many methods have been proposed in the literature to perform admission control in order to provide a sufficient level of Quality of Service (QoS) to accepted flows. In this paper, we introduce a novel data-driven method based on a time-varying model that we refer to as Knowledge-Based Admission Control solution (KBAC). Our KBAC solution consists of three(More)

In this PhD thesis, we consider heterogeneous Wireless Sensor Networks (WSNs) in which several sensing devices with different characteristics coexist. In contrast to a homogeneous sensor network, in heterogeneous networks different sensors may sense different physical phenomena generating traffic that have different characteristics such as monitoring(More)

A wireless sensor is a small electronic device capable of measuring a physical value (temperature, light, etc.) and communicating wirelessly. Because of the network's large size (100+ nodes), communicating with the collecting node – called sink – must be done in an ad-hoc multi-hop manner, as a single sensor can only communicate with a small number of(More)
