    Abstract: A time synchronization method in a wireless sensor network, a low power routing method using a reservation scheme, and an apparatus for performing the method are provided. The time synchronization method in the wireless sensor network may include: receiving a first synchronization request command packet from a parent node that manages time synchronization for a predetermined synchronization region; receiving, from the parent node, a second synchronization request command packet that has a transmission timestamp value of the first synchronization request command packet; and performing time synchronization for a child node based on a reception time of the first synchronization request command packet, a reception time of the second synchronization request command packet, and the transmission timestamp value of the first synchronization request command packet.

    Abstract: 무선 센서 네트워크에서의 선행적 데이터 필터링을 위한 센서노드의 센싱 데이터 전송장치 및 방법이 개시된다. 이 장치 및 방법은 센싱 데이터에 대한 요청 쿼리 및 타이머 파라미터를 수신하고, 수신된 요청쿼리에 따라 센서노드에 감지된 로컬센싱데이터를 검출하고, 요청쿼리를 기초로 타이머 파라미터를 적용한 타이머의 구동시간을 설정하여 설정된 타이머의 구동시간 동안 센서노드의 무선수신범위에 있는 이웃센서노드의 센싱 데이터를 오버히어링하여 로컬센싱데이터가 상기 이웃센서노드의 센싱 데이터와 중복되지 않는 경우에 로컬센싱데이터를 전송한다. 본 발명에 따르면, 데이터 전달 경로를 노드의 에너지 잔량을 고려하여 선정하게 함으로써 노드의 에너지 소진을 분산시켜 네트워크의 수명을 향상시키는 효과가 있다.

    Abstract: A communication apparatus in wireless sensor network and a method thereof are provided to remove instability of a network, thereby improving stabilization of a sensor network. If a connection setting failure report message is received from an error generating bridge system, a search unit searches a newly used channel and a bridge system(240) performing channel switching. An information management unit replaces information about sensor nodes(210) connected to the searched bridge system with information about sensor nodes newly connected to the searched bridge system through a channel.
