METHOD OF MANAGING FAULT BY A BASE STATION IN VESSEL USN WITH DESIGNATING CLUSTER HEAD

The present invention relates to a method for clustering of a vessel USN with designation of a cluster head in a vessel USN system, wherein the method comprises the steps of receiving information on residual energy from multiple nodes and a cluster head after one cycle expires; and designating a cluster head among the nodes based on the information on residual energy. According to the present invention, energy consumption on communications among the nodes can be reduced since the designation of a cluster head based on residual energy is used. And, the cluster head is not replaced frequently, thereby providing economic feasibility and stable communications among the nodes. In addition, when a fault occurs in the cluster head of the vessel USN, the entire re-clustering can be avoided and rearrangement of overlapping cluster heads is not required. Moreover, it is possible to reduce inconvenience resulting from communications required for exchange of state information among cluster heads.
