  • Patent number: 8289190
    Abstract: Provided are an adaptive communication method and a sensor node for performing the same. The sensor node adaptively selects transmitted signal output strength and a wakeup zone of transmitted data based on a received signal strength indication of a control packet received from a sink node and existence of an obstacle acquired through a sensor, and transmits data based on the adaptive selection. Also, during an operation as a receive mode, the sensor node wakes up and determines whether to receive the data from the transmit node based on wakeup zone configuration information per sensor node received from the sink node and a wakeup zone selected by a sensor node currently operable as a transmit node.

  • Publication number: 20120185112
    Abstract: Disclosed herein is an apparatus and method for detecting the location of a vehicle using results sensed by sensing devices installed outside the vehicle and the internal information of the vehicle without obtaining the current location information of the vehicle using signals transmitted from a Global Positioning System (GPS) satellite. The apparatus for detecting the location of a vehicle includes a location information reception unit for receiving location information that is generated by sensing a vehicle passing by a sensing point and that corresponds to the sensing point. A location detection unit estimates a current location of the vehicle based on information sensed by internal sensors of the vehicle and control information for a vehicle manipulation part while the location information is not received, and corrects the estimated current location of the vehicle using received location information when the location information is received.

  • Publication number: 20100260167
    Abstract: 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.
