Abstract: PURPOSE: A system and method for monitoring a road slope collision are provided to take prior measures before a section is collided by predicting possibilities of a road slope collision based on underground information of the road slope. CONSTITUTION: A method for monitoring a road slope collision is as follows. Underground information of a road slope is measured. Whether the measured underground information is exceeded a critical value of the underground information based on possibilities of a road slope collision or not is confirmed. If the measured underground information is exceeded the critical value, an inclination of the road slope is measured by driving a sensor. If the measured inclination of the road slope is exceeded a critical inclination value, the road slope is decided to be collided.

Abstract: PURPOSE: A cluster based data transmission method in a wireless sensor network is provided to improve the efficiency of data integration by concentrating the transmission of data to a specific cluster head. CONSTITUTION: A border node is located in the edge of a cluster. A temporary cluster head is temporarily selected as a cluster head among a plurality of border nodes. If a target is detected by at least one of the border nodes within a temporary cluster including the border node and the temporary cluster head, the temporary cluster head collects data from the border node. The temporary cluster head transfers the data to its own cluster head.

Abstract: A method for managing node faults in a sensor network and a fault generation report apparatus for the same are provided to determine a type and class of the node fault generated in a node configuring the sensor network and report the determination result to an upper node, so that an upper system is able to effectively manage the node faults and grasp a state of the sensor network. A node fault processor(224,226,228) determines a fault ID(Identification) indicating a type of a fault and a fault class showing a degree of the fault when a frequency of faults generated in a node is bigger than a predetermined frequency. A message generator(222) generates a fault report message including the determined fault ID and fault class, and transmits the generated fault report message to an upper node. A memory(230) stores matching information of the fault glass and the degree of the node faults.

Abstract: A topology management method of a sensor network using a topology management table is provided to enable a sink node to receive a report on topology information through communication between parent and child nodes and manage topology information of the sensor network, thereby efficiently maintaining/managing the topology information of the sensor network which is continuously changed. If a new child node is added to a parent node, a child node ID is allocated to the added child node, and the child node and the parent node individually generate topology management tables(200). The parent node reports changed topology information to a sink node from the topology management table(210,220). The sink node compares the reported topology information with the overall topology information. If a parent node of sibling of the added child node is different from the existing parent node of the overall topology information, deletion information of the added child node is notified to the existing parent node.
