Abstract

Des modes de réalisation comprennent des procédés destinés à une collecte coopérative, décentralisée de données parmi des dispositifs électroniques, et des dispositifs et systèmes réalisant de tels procédés. Lorsqu'un dispositif détermine l'occurrence d'un événement, il génère un identifiant EID (identifiant d'événement) unique, utilisé pour associer toutes les données relatives à l'événement. Le dispositif diffuse à des dispositifs proches un message de demande, comprenant l'identifiant EID et facultativement un événement de description d'événement et une ou plusieurs actions demandées. Les actions demandées peuvent comprendre des instructions pour surveiller l'événement et rapporter des informations à un référentiel central. Lorsqu'un dispositif reçoit le message de demande, il y répond selon les actions demandées et toute autre information contenue dans le message. Le dispositif émetteur et le dispositif récepteur peuvent envoyer des messages de rapport d'événement, comprenant l'identifiant EID et des informations capturées, au référentiel qui peut ensuite traiter les informations reçues en provenance des dispositifs à l'aide de l'identifiant EID afin d'agréger toutes les informations significatives de l'événement.
