Abstract:
(EN) A fixed wireless communication apparatus in a system that comprises the fixed wireless communication apparatus and a plurality of mobile wireless communication apparatuses incorporated respectively in a plurality of mobile bodies and that selects a leader from among the plurality of mobile bodies through a CSMA/CA mode wireless communication, the fixed wireless communication apparatus comprising: a message reception unit 202 that receives periodic messages transmitted periodically from the mobile wireless communication apparatuses; a reception timing recording unit 203 that records the reception timings of the periodic messages; a transmission timing decision unit 106 that allocates, on the basis of the reception timings of the periodic messages, transmission timings to the respective mobile wireless communication apparatuses; a leader candidate determination unit 105 that determines mobile bodies serving as leader candidates from among the mobile bodies incorporating the mobile wireless communication apparatuses that are the transmission sources of the received periodic messages; and a message transmission unit 107 that creates a vote request message to notify the mobile wireless communication apparatuses of a leader selection vote commencement, the mobile bodies serving as the leader candidates, and the allocated transmission timings.
(FR) L'invention porte sur un appareil de communication sans fil fixe dans un système comprenant l'appareil de communication sans fil fixe et une pluralité d'appareils de communication sans fil mobiles incorporés respectivement dans une pluralité de corps mobiles, lequel système sélectionne un leader parmi la pluralité de corps mobiles par l'intermédiaire d'une communication sans fil en mode CSMA/CA, l'appareil de communication sans fil fixe comprend : une unité de réception de message 202 qui reçoit des messages périodiques transmis périodiquement à partir des appareils de communication sans fil mobiles ; une unité d'enregistrement de synchronisation de réception 203 qui enregistre les séquences de réception des messages périodiques ; une unité de décision de synchronisation de transmission 106 qui attribue, sur la base des séquences de réception des messages périodiques, des temporisations de transmission aux appareils de communication sans fil mobiles respectifs ; une unité de détermination de candidats leaders 105 qui détermine des corps mobiles servant de candidats leaders parmi les corps mobiles incorporant les appareils de communication sans fil mobiles qui sont les sources de transmission des messages périodiques reçus ; et une unité de transmission de message 107 qui crée un message de requête de vote pour avertir les appareils de communication sans fil mobiles d'un début de vote de sélection leader, les corps mobiles servant de candidats leaders, et les temps de transmission attribués.
(JA) 固定無線通信装置と複数の移動体にそれぞれ搭載された複数の移動無線通信装置とを備え、CSMA/CA方式の無線通信により複数の移動体からリーダを選出するシステムにおける固定無線通信装置であって、移動無線通信装置から周期的に送信された周期メッセージを受信するメッセージ受信部202と、周期メッセージの受信タイミングを記録する受信タイミング記録部203と、周期メッセージの受信タイミングに基づいて、それぞれの移動無線通信装置に対して送信タイミングを割り当てる送信タイミング決定部106と、受信した周期メッセージの送信元である移動無線通信装置を搭載する移動体のなかからリーダ候補にする移動体を判定するリーダ候補判定部105と、リーダ選出の投票開始とリーダ候補の移動体と割当てした送信タイミングとを移動無線通信装置に通知する投票要求メッセージを作成するメッセージ送信部107と、を備える。
