Architectures cross-layer PHY/MAC pour réduire l'effet de blocage de réception dans les réseaux véhiculaires ad-hoc, Cross-layer designs PHY/MAC for receiver blocking problem in vehicular ad-hoc networks

Basma Bouraoui

Le protocole MAC du standard IEEE 802.11p dédié aux réseaux véhiculaires interdit les transmissions simultanées dans une même zone de détection afin d’éviter d’éventuelles interférences entre les véhicules voisins. Cette interdiction entraîne un blocage temporaire de réception de données, ce qui…, The MAC protocol IEEE 802.11p, dedicated to vehicular ad-hoc networks VANETs, prohibits simultaneous transmissions in the same detection area, in order to avoid interference between neighboring vehicles. This prohibition causes a temporary data reception blocking, which reduces the network…

A cost-effective approach for spectrum sensing using beamforming

Kais Bouallegue, Iyad Dayoub, M Gharbi, Kaïs Hassan

Spectrum sensing (SS) is one of the principal challenges on which the mobile communication is based on. Identifying the available frequency bands, also called white spaces, is the main issue. A novel blind approach for SS in the narrowband context is proposed in order to improve the signal…

Light-controlled flows in active fluids

Julien Dervaux, Marina Capellazzi Resta, Philippe Brunet

Many photosynthetic microorganisms are able to detect light and move toward optimal intensities. This ability, known as phototaxis, plays a major role in ecology by affecting natural phytoplankton mass transfers and has important applications in bioreactor and artificial microswimmers technologies…
