Abstract: PURPOSE: A ship sensor network and an effective data merging method are provided to increase the lifetime of a network by reducing the amount of data transmission. CONSTITUTION: A plurality of sensor nodes(1-3) compares a collected average value of a data value with a current data value which is periodically collected. The plurality of the sensor nodes transmits the current data to a cluster head(10) when the current data value is over the average value. The cluster head transmits an average value of a data value transmitted from a plurality of the sensor nodes to a synchronization node(20). The synchronization node transmits the average value transmitted from the cluster head to an upper analysis system.

Abstract: According to the present invention, the packet transmission time of a sensor node is reduced as the query is small and the length of a packet is closely related to the packet transmission time of the sensor node thus reducing energy consumption by performing a selective query to increase the time of a life than a conventional method. Additionally, the packet transmission time thereof is increased depending on the selective query and approximately 1.5% of energy is decreased in terms of energy consumption and the conventional method if the selective query is two, by which the simulation of the packet transmission depending on the selective query confirms the energy consumption of the sensor node and confirms a data success rate via the simulation when an event happens using an NS-2 simulator in order to compare of energy efficiency and the conventional method.

Abstract: PURPOSE: A red tidal current recognition method using PCA(principal component analysis) and roundness is provided to recognize images without having a reference point of a red tidal image by using entropy and the roundness. CONSTITUTION: A vector set of a learning image is constructed by learning a red tide image through PCA(100). A candidate recognition image group is constructed by calculating the roundness of the learning image and inputted image and selecting an image which is close to the roundness(200). Entropy of an image in the candidate recognition image group is calculated(300). The entropy selects a recognition image by calculating the entropy of images in the candidate recognition image group.
