    • The present invention relates to a time synchronization method in a wireless sensor network. In the present invention, if an upper node requests a lower reference node to start time synchronization, the lower reference node broadcasts a first sync reference packet. The upper node receives the first sync reference packet and transmits the first sync reference packet reception time to the lower reference node. The lower reference node broadcasts the first sync reference packet reception time, such that the other nodes perform time synchronization on the basis of the first sync reference packet reception time. Meanwhile, the lower reference node estimates the first sync reference packet reception time of the upper node to calculate the reception estimation time, and transmits the reception estimation time to a determination node that is two hops anterior to the lower reference node. Therefore, the determination node compares the reception time received from the upper node and the reception estimation time received from the lower reference node and determines whether a capture attack on the upper node has occurred.
    • 本发明涉及无线传感器网络中的时间同步方法。 在本发明中,如果上层节点请求较低参考节点开始时间同步,则下参考节点广播第一同步参考分组。 上级节点接收第一同步参考分组,并将第一同步参考分组接收时间发送到下参考节点。 下参考节点广播第一同步参考分组接收时间,使得其他节点基于第一同步参考分组接收时间执行时间同步。 同时,下参考节点估计上级节点的第一同步参考分组接收时间以计算接收估计时间,并且将接收估计时间发送到作为下参考节点之前的两跳的确定节点。 因此,确定节点比较从上层节点接收到的接收时间和从较低参考节点接收的接收估计时间,并确定是否发生了对上层节点的捕获攻击。
