Abstract: A method for transmitting sensing information in a wireless sensor network having a pair of nodes is provided to determine the fault of a sensor node and a pair node using only sensing information collected by the sensor node and the pair node, which are installed in the same target area to sense information, thereby having no need of additional cost to be economical and efficient. A method for transmitting sensing information in a wireless sensor network comprises the following steps of: setting sensor nodes(301,302) installed in the same target area into a pair of nodes which transceive sensing information each other; allowing one of the sensor nodes set as the pair of nodes to transmit first sensing information(c1), which the sensor nodes sense, to the other sensor node in the pair of nodes; allowing the sensor nodes set as the pair of nodes to transmit the first sensing information and second sensing information(c2) received from the other sensor node in the pair of nodes to a parent node(306); and allowing the parent node to transmit the first and second sensing information to a sink node(308).

Abstract: A method and a system for guiding a visitor using the sensor network are provided to guide the visitor from a starting position to a destination position or from the destination position to the starting position through a visitor terminal by using the sensor network constructed in a building. An entry approver requests entry of a visitor to a terminal(70) of a person to visit according to destination information received from the visitor. A course setting part sets a course for guiding the visitor terminal(10) to the destination position by using the destination information of the visitor according to an approval of the terminal of a person to visit. A location searcher searches and provides a current position of the visitor terminal by using a visitor terminal ID obtained through the sensor network and location information of a sensor node(20) communicating with the visitor terminal. A location checker checks whether the present location of the visitor searched from the location searcher is out of a predetermined range. A door controller enables the visitor terminal to open/close a door installed at the destination position.

Abstract: PURPOSE: A synchronization controlling method is provided to prevent degradation of stability and interference between output clocks by adding an intermediate transition mode. CONSTITUTION: A free-running mode(1) maintains stability of an oscillator in a phase-locked loop. A fast mode(2) enables an output clock of the phase-locked loop to be frequency synchronized with the reference clock. A hold fast mode(3) returns to the fast mode(2) in step(15) if a frequency of the reference clock becomes within an oscillation range of an oscillator, and transits to the free-running mode(1) in step(16) if the frequency of the reference clock is out of the oscillation range. A hold normal mode(5) operates upon the frequency difference between the output clocks in step(17). A fine normal mode(6) operates upon the coincidence between the output clock of the phase-locked loop and the phase of the reference clock in step(13).
