There is provided a network join method including transmitting a long beacon message including transmission timing information of a first short beacon message to a child node network device, transmitting a first short beacon message including information regarding an interval in which it is possible to transmit a message, to the child node network device according to a transmission timing of the first short beacon message, receiving a slot allocation request message from the child node network device according to the interval in which it is possible to transmit a message, and checking whether the child node network device joins a network, and transmitting a slot allocation confirmation message to the child node network device.

Network join method and network device using the network join method

A communication connecting method between nodes through a network, includes: storing communication connection information acquired through searching for communication entities of other nodes; determining whether communication connection information on a communication entity of a connection target node exists by searching for the stored communication connection information; and configuring communication connection with the communication entity of the connection target node based on the determination result.

Node and communication connecting method between nodes

Provided is a cruise control system and method. A vehicle cruise control system collects state information of components inside and outside a vehicle, state information of a road on which the vehicle is provided, and drive pattern information of a driver of the vehicle, analyzes a mileage amount and an exhaust gas emission amount of the vehicle based on the collected state information of the components, the road state information, and the drive pattern information, calculates a cruise control speed based on the analysis result, and controls the vehicle to run at the cruise control speed.

Cruise control system and method thereof

A node constituting data distribution service (DDS) structure according to an exemplary embodiment of the present invention includes a first DDS application including a first DCPS layer and a first real-time publish-subscribe (RTPS) layer and a second DDS application including a second DCPS layer communicated with the first RTPS layer.

DDS structure with scalability and adaptability and node constituting the same

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.

Time synchronization method in wireless sensor network

Provided is a wireless communication method in a wireless sensor network environment. The method overhears a packet transmitted from a source sensor node to a destination sink node and determines whether the destination sink node receives the packet. A transmission node selected by using local information among a plurality of neighboring sensor nodes transmits the overheard packet to the destination sink node when the packet is not received.

Method for wireless communication in wireless sensor network environment

An apparatus is for guiding a vehicle traveling of a vehicle by using information technology infrastructures. The apparatus includes: a control terminal for controlling the vehicle traveling; sensing devices that collect circumstance information of guidance areas desirous of guiding the vehicle by using the information technology infrastructures provided on the guidance areas; and a server device that recognizes a circumstance of the guidance areas to create a guidance route based on the collected circumstance information by the sensing device so that the control terminal controls the vehicle to travel along the guidance route.

System and method for autonomous vehicle guiding using information technology infrastructure and server apparatus therefor

Provided are a method for running a network for vehicle detection and a system thereof. Each vehicle detecting device is classified into a plurality of groups based on information provided from the vehicle detecting devices and control information that activates or deactivates components of the corresponding vehicle detecting devices is set for each group based on the information. Power of a signal transmitting the information is set for each vehicle detecting device.

Method for running vehicles detecting network and system thereof

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.

Adaptive communication method and sensor node for performing the method

The present invention relates to a method and apparatus for delivering data based on a sensor network. According to an embodiment of the present invention, the apparatus for delivering data is provided in a means of transportation such as a vehicle, activates a node of a corresponding sensor network when a vehicle enters a road segment, and receives data from the transmission node. Then, the apparatus for delivering data calculates an optimum path along which the received data is delivered to a target destination, determines whether to use other vehicles or to directly deliver the data to the target destination on the basis of the calculated optimum path, and delivers the data to the target destination by the determined method. In this case, the target destination to which the data is delivered may be a different node of the same sensor network, or may be a node or a center of a different sensor network.
