METHOD OF CONSTITUTING CLUSTER BY SENSOR NETWORK USING FUZZY LOGIC

摘要

PURPOSE: A cluster formation method of a sensor network using a fuzzy logic multiplying a life span is provided to efficiently extend the lifetime of the sensor network. CONSTITUTION: A sensor node receives a cluster head supporting message of an adjacent sensor node(S5). The cluster head selection opportunity value of the task sensor node is bigger than the cluster head election opportunity value of the sensor node(S6). The cluster head information and head election opportunity value information of the task sensor node maintain(S7). The cluster head is selected while the sensor nodes support the cluster head(S8, S9). The cluster is formed into the cluster head and the sensor node which is contiguous to the cluster head.
