Abstract: A method of comprehensively monitoring slopes based on a wireless network in a sensor node is provided. The method includes acquiring sensing data of first sensing frequencies for determining a risk to the slopes, transmitting the acquired sensing data of first sensing frequencies to an analysis server through a gateway, acquiring sensing data of second sensing frequencies for determining the risk to the slopes when operation mode received from the analysis server through the gateway is precision mode, and transmitting the acquired sensing data of second sensing frequencies to the analysis server through the gateway.

Abstract: The present invention relates to a method for cluster based data in wireless sensor networks. The method includes: selecting any one of border nodes positioned at the edge of a cluster as a temporary cluster head as a temporary cluster head when a target is sensed in the cluster; bugging data of the temporary cluster head by border nodes in other adjacent cluster which do not sense the target to temporarily change the border node selected as the temporary cluster head to a cluster head of each of the border nodes; when the target is sensed by at least one of the border nodes, collecting data from each of the border nodes by the temporary cluster head to transferring the collected data to an actual cluster head of the temporary cluster head; and aggregating the collected data by actual cluster head of the temporary cluster head.

Abstract: Provided are a simulation apparatus and method used to simulate a sensor network. A sensor node of a real node is reflected in a simulation, and bidirectional communication is performed between a real node and a virtual node, in order to reflect a real environment and a simulation environment in each other and make the real node and the virtual node consistent with each other, thereby performing simulation.

Abstract: A plug and play sensor module and sensor node are provided. The plug and play sensor module includes a sensor, a sensor interface that transmits and receives a signal for plug and play connection to and from a sensor node, and a plug and play connection processing unit that transmits a signal for connection confirmation to the sensor node through the sensor interface when being connected to the sensor node, and transmits sensor identification (ID) information to the sensor node when a sensor ID is requested by the sensor node.

Abstract: A method for effectively using power resource in a wireless mesh network is disclosed to select and change a level of a power saving mode according to terminal and network situations to increase the duration of the network's existence as well as improve the power consumption of each mesh terminal. After active mesh terminals that are to perform a data relay function and super-saving mesh terminals that are not to perform the data relay function are selected in consideration of a network topology at certain periods, the level of a power saving mode of the mesh terminals selected as the super-saving mesh terminals is higher than that of the mesh terminals selected as the active mesh terminals. And then, a routing path in a tree form is formed along the mesh terminals selected as the active mesh terminals to transmit data.
