Abstract
(EN)
A management node for a wireless communication system configured from a plurality of communication nodes that operate by switching between a first mode in which data is not relayed and a second mode in which data is relayed in accordance with a command, wherein when the communication nodes to which the wireless communication distance from the management node is n hops (where n is a natural number) are specified, a command to operate in the second mode is issued (S17) to a communication node, from among communication nodes for which the wireless communication distance is n hops, that is capable of communicating directly with the largest number of communication nodes not included in the specified communication nodes (S14, S15).
(FR)
L'invention concerne un nœud de gestion pour un système de communication sans fil configuré à partir d'une pluralité de nœuds de communication qui fonctionnent par commutation entre un premier mode dans lequel des données ne sont pas relayées et un second mode dans lequel des données sont relayées conformément à une commande. Lorsque les nœuds de communication auxquels la distance de communication sans fil du nœud de gestion est de n sauts (où n est un nombre naturel) sont spécifiés, une commande pour fonctionner dans le second mode est émise (S17) vers un nœud de communication, parmi des nœuds de communication pour lesquels la distance de communication sans fil est de n sauts, qui est capable de communiquer directement avec le plus grand nombre de nœuds de communication qui ne sont pas inclus dans les nœuds de communication spécifiés (S14, S15).
(JA)
データを中継しない第1のモードとデータを中継する第2のモードとを指示に応じて切り替えて動作する複数の通信ノードで構成された無線通信システムの管理ノードであって、前記管理ノードからの無線通信距離がnホップ(nは自然数)までの通信ノードが特定されているとき、無線通信距離がnホップである通信ノードのうち、前記特定されている通信ノードに含まれない最多数の通信ノードと直接通信可能な通信ノードに対し(S14、S15)、前記第2のモードで動作するよう指示する(S17)。
