Abstract

Des modes de réalisation de la présente divulgation concernent des nœuds de détection, un procédé et un support lisible par ordinateur pour une ISAC. Un premier nœud de détection détermine un schéma de rapport pour un résultat de détection sur la base d'un mode de détection et/ou d'un type du premier nœud de détection. À son tour, le premier nœud de détection obtient le résultat de détection sur la base du schéma de rapport.
