Abstract
(EN)
A communication terminal provided with: a control information sharing means which notifies an adjacent terminal of control information including at least the number of adjacent terminals as information, and which acquires from the adjacent terminal the control information of the adjacent terminal; a relay terminal selection means which, on the basis of the control information, selects as a relay terminal a communication terminal capable of directly communicating with all communication terminals in a wireless ad-hoc network; a transmission power control means which adjusts transmission power in accordance with the result of selection by the relay terminal selection means; a reselection necessity determination means which determines whether another communication terminal should become a new relay terminal, and which, upon determining that another communication terminal should become a new relay terminal, computes the priority of the communication terminals in the wireless ad-hoc network; and a relay terminal reselection request means which performs, in accordance with the priority, a relay terminal reselection request process for transmitting a relay terminal reselection request included in the control information. The control information sharing means delivers the relay terminal reselection request, and the transmission power control means adjusts the transmission power on the basis of the relay terminal reselection request.

L’invention concerne un terminal de communication comprenant : un moyen de partage d'informations de commande qui notifie à un terminal adjacent des informations de commande comprenant au moins le nombre de terminaux adjacents en tant qu'informations et qui acquiert, du terminal adjacent, les informations de commande du terminal adjacent ; un moyen de sélection de terminal relais qui, sur la base des informations de commande, sélectionne comme terminal relais un terminal de communication apte à communiquer directement avec tous les terminaux de communication dans un réseau ad hoc sans fil ; un moyen de contrôle de puissance de transmission qui ajuste la puissance de transmission en fonction du résultat de la sélection par le moyen de sélection de terminal relais ; un moyen de détermination de nécessité de resélection qui détermine si un autre terminal de communication doit devenir un nouveau terminal relais et qui, lorsqu’il est déterminé qu'un autre terminal de communication doit devenir un nouveau terminal relais, calcule la priorité des terminaux de communication dans le réseau ad hoc sans fil ; et un moyen de demande de resélection de terminal relais qui, d’après à la priorité, exécute un processus de demande de resélection de terminal relais pour transmettre une demande de resélection de terminal relais comprise dans les informations de commande. Le moyen de partage d'informations de commande délivre la demande de resélection de terminal relais, et le moyen de contrôle de puissance de transmission ajuste la puissance de transmission sur la base de la demande de resélection de terminal relais.
