Abstract: front page image
(EN)The present invention relates to a double-linked wireless sensor network enabling bidirectional communication and a method for transmitting and receiving data. Each node that constitutes the wireless sensor network repeatedly passes between active and inactive sections, and the active section consists of an uplink section, an idle section and a downlink section. In the uplink and downlink sections, a second receiving section, a second reception-processing section, a first receiving section, a first reception-processing section, a transmitting section, a transmission-processing section, a first confirming section, a first confirmation-processing section, a second confirming section, and a second confirmation-processing section are sequentially formed so that the bidirectional communication between a synchronized node and a terminal node may be enabled within a single period of the active section. The wireless sensor network according to the present invention maintains the transmission-processing section (TXP) at a receiving mode at which data can be received from another node so that a new node may be easily joined to the network as a terminal node or an intermediate node. In addition, the wireless sensor network according to the present invention includes two consecutive receiving sections in the uplink and downlink sections. Therefore, the wireless sensor network is able to easily perform a recovery operation even when the link between two consecutive nodes is disconnected.
(FR)L'invention porte sur un réseau de capteurs sans fil à double liaison et à communication bidirectionnelle, et sur un procédé associé. Selon l'invention, chaque noeud constituant le réseau de capteurs sans fil passe de manière répétée entre des sections actives et des sections inactives, la section active comprenant une section de liaison montante, une section de repos et une section de liaison descendante. Les sections de liaison montante et de liaison descendante comprennent, établies dans cet ordre: une seconde section de réception, une seconde section de traitement de réception, une première section de réception, une première section de traitement de réception, une section de transmission, un section de traitement de transmission, une première section de confirmation, une première section de traitement de confirmation, une seconde section de confirmation et une seconde section de traitement de confirmation, de manière qu'une communication bidirectionnelle peut s'établir entre un noeud synchronisé et un noeud terminal dans les limites d'une seule période de la section active. Le réseau de capteurs sans fil précité maintient la section de traitement de transmission (TXP) dans un mode de réception dans lequel des données peuvent être reçues en provenance d'un autre noeud, de sorte qu'un nouveau noeud peut facilement rejoindre le réseau comme noeud terminal ou comme noeud intermédiaire. En outre, le réseau de capteurs sans fil précité comprend deux sections de réception consécutives dans la section de liaison montante et dans la section de liaison descendante, ce qui lui permet d'effectuer sans difficulté une opération de récupération, même lorsque la liaison entre deux noeuds consécutifs est interrompue.
(KO)본 발명은 양방향 통신이 가능한 이중 링크된 무선 센서 네트워크 및 데이터 송수신 방법에 관한 것이다. 상기 무선 센서 네트워크를 구성하는 각 노드는 활성 구간 및 비활성 구간을 반복적으로 수행하며, 상기 활성 구간은 업링크 구간, 휴지 구간, 다운링크 구간을 구비한다. 상기 다운링크 구간 및 업링크 구간은 각각 제2 수신 구간, 제2 수신 처리 구간, 제1 수신 구간, 제1 수신 처리 구간, 송신 구간, 송신 처리 구간, 제1 확인 구간, 제1 확인 처리 구간, 제2 확인 구간, 제2 확인 처리 구간이 순차적으로 구성되어, 활성 구간의 단일 주기내에서 싱크 노드와 단말 노드간의 양방향 통신을 수행할 수 있다. 본 발명에 따른 무선 센서 네트워크는 송신 처리 구간(TXP)을 다른 노드로부터 데이터를 수신할 수 있는 수신 모드로 유지함으로써, 신규 노드가 단말 노드 또는 중간 노드로 쉽게 합류(Join)할 수 있게 된다. 또한, 본 발명에 따른 무선 센서 네트워크는 업링크 구간 및 다운링크 구간의 각각에 연속되는 2개의 수신 구간을 구비함으로써, 연속되는 2개의 노드에 대한 링크가 끊어지더라도 간단하게 복구(Recovery)할 수 있게 된다.
