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. 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.

Abstract: A vehicle detection apparatus and an operation method thereof are provided to minimize unnecessary power consumption, thereby operating for a longer time. A vehicle detection apparatus waits until an operation command is received from a corresponding access point(S106). The vehicle detection apparatus transmits generated vehicle detection information to the access point(S109). The vehicle detection apparatus maintains a normal mode during predetermined time based on a changing period of an operation mode and repeatedly performs a vehicle detection operation and a transmission operation of vehicle detection information(S110). If a changing period of the operation mode is reached, the vehicle detection apparatus enters into a sleep mode and maintains the sleep mode during predetermined time(S111).

Abstract: A time synchronization method in a wireless sensor network is provided to reduce an overhead by decreasing the packet exchange times between adjacent nodes by broadcasting a synchronous reference packet twice by a reference node. If the start synchronization request packet is received from an upper node(S101), a reference node broadcasts the first synchronization reference packet(S102). The upper node records a fist receiving time of receiving a first synchronization reference packet(S103). The upper node transmits the response packet including the first receiving time to the reference node(S104). The reference node broadcasts a synchronization reference packet including the first receiving time(S105). At least one node adjacent to the reference node performs time-synchronization based on the first receiving unit(S106).

Abstract: A method and a system for providing intersection information are provided to easily determine a part to be blamed of a car accident by determining a passing priority of vehicles based on data collected from sensor nodes. An intersection information providing system includes sensor nodes(100), a controller(200), and a display device(300). The sensor nodes are implemented on a road surface or a road side and collect magnetic field variation data from a vehicle or an organic member. The controller determines an arrival timing of the vehicle based on the collected data and determines whether the vehicle or the organic member violates a safety driving regulation for the road. The controller determines a passing priority for the vehicle and the organic member. The display device provides a vehicle passing signal and violation information to users according to the determined priority.
