Abstract

L'invention concerne un mécanisme amélioré facilitant la transmission de petits paquets dans un réseau de pairs ad-hoc. Un petit paquet est identifié au niveau d'un récepteur dans un canal de commande, de sorte que sa puissance inférieure puisse être prise en compte dans le cadre d'un protocole de gestion des interférences mis en œuvre au sein de dispositifs de pairs locaux. Dans un intervalle de trafic, un émetteur diminue volontairement sa puissance de transmission dans la mesure où un petit paquet nécessite un rapport signal-bruit beaucoup plus faible, ce qui, d'une part, améliore le rapport de l'énergie du signal par bit à la densité de puissance du bruit pour la transmission; et, d'autre part, réduit au minimum l'interférence causée aux autres communications sans fil en train de se dérouler dans le même spectre.
