摘要： A beacon scheduling method and system in a network system. The beacon scheduling method of a router in a network system that includes at least one router, includes receiving a beacon signal from a parent node; calculating a difference between an address of the parent node and an address of the router; and setting the calculated difference to a beacon transmission offset of the router. Accordingly, all devices from the top to the bottom of the network can transmit their beacons without collisions, and thus the multi-hop tree structure can be established.

摘要： A routing method comprising receiving a first packet, the first packet being broadcast for discovery of a route. A first backoff of the first packet is calculated based on a route cost of the first packet. The first packet is rebroadcast if a second packet is not received within the first backoff, the second packet being a duplicate of the first packet. A second backoff of the second packet is calculated based on a route cost of the second packet if the second packet is received within the first backoff. One of the first and the second packets is rebroadcast as a result of comparing the first backoff and the second backoff.

摘要： The present invention discloses an apparatus and method for avoiding mutual interference between wireless communication systems. A measurement unit measures the strength of a signal received through a channel to be used in a transmission slot for a switching time of a reception mode and a transmission mode. A judgment unit compares the strength of the received signal with the strength of a reference signal, and judges data transmission. A control unit outputs a signal for performing a transmission operation of the data according to the judgment of the judgment unit. The wireless communication system transmits the data according to the input signal from the control unit. The data transmission is decided by confirming the state of the transmission slot, thereby avoiding collision with a communication apparatus using a frequency identical to a frequency of the channel of the transmission slot.

摘要： A time synchronization method in a wireless sensor network, has an upper node that provides back-off scheduling to lower nodes in the wireless sensor network of a hierarchical structure. Each of the lower nodes synchronizes time according to the back-off scheduling based on its local clock. The time synchronous method also allows the number of packets required for synchronization in the wireless sensor network to sharply decrease, and the life time of the network to increase. Additionally, the time synchronous method provides a response packet from a lower node in response to a synchronization packet from an upper node, which is used as a synchronization start packet for secondary lower nodes, so that synchronization in the entire network is rapidly processed.

摘要： Disclosed herein is a torsion beam suspension system for automobiles and a method of manufacturing the same. In the present invention, a wheel is coupled to a spindle bracket such that the center of the spindle bracket is placed in front of the center of the wheel, so that, when the spindle bracket is bent by a lateral force applied to the automobile, the toe angle of the wheel varies such that a toe-in occurs. This toe-in motion of the wheel can prevent the wheel from being toed-out due to a lateral force when the automobile turns. Therefore, the present invention prevents the automobile from oversteering when turning, thus enhancing the steering stability of the automobile.

摘要： A wireless communication apparatus, a wireless communication method thereof, and a wireless communication system employing the same. A master device of the wireless communication system requests one slave device of a network to perform a function of a master device for a predetermined time, and sends Piconet information about other slave devices of the network, while the one slave device receives the Piconet information from the master device and communicates with the other slave devices of the network for a predetermined time as a temporary master device. Accordingly, the one slave device becomes a dynamic master device and communicates with the other slave devices by using a frequency hopping sequence and a clock of a previous master device as they are, there is no need to transmit the frequency hopping sequence and the clock of the new master device to the slave devices, and accordingly, much time can be saved.
