Abstract

L'invention concerne un procédé et un appareil de distribution d'énergie pour un réseau de transfert d'énergie sans fil, et un dispositif informatique. Le procédé comprend les étapes suivantes : en prenant le fait que la puissance de transmission d'un nœud d'envoi dans une liaison de communication dans un réseau de transfert d'énergie sans fil satisfait une exigence de transmission de la liaison de communication comme condition de contrainte, et en prenant la maximisation d'une probabilité de connexion sécurisée de la liaison de communication comme objectif, déterminer un problème d'optimisation, le problème d'optimisation étant déterminé au moins sur la base d'une relation d'association entre la puissance d'interférence d'un nœud de destination dans la liaison de communication et la puissance de transmission du nœud d'envoi, et de la probabilité d'une connexion sécurisée ; et sur la base du problème d'optimisation du réseau de transfert d'énergie sans fil, déterminer une valeur de puissance de transmission optimale du nœud d'envoi dans la liaison de communication dans le réseau de transfert d'énergie sans fil inférieure à la valeur de chaque rapport de distribution de puissance.
