SENSOR NETWORK AND CLUSTERING METHOD FOR SENSOR NETWORK

摘要

PURPOSE: A clustering method for a sensor network is provided to efficiently select a cluster head in an energy consumption point of view. CONSTITUTION: Each sensor node transmits consumed energy quantity information for a predetermined period to a BS(Base Station)(S110). The BS determines a probability value(S130). The probability shows the possibility that each sensor node is selected as a cluster header. Each sensor node selects a random value for the comparison with the probability value(S140). By the comparison result between the random value and the probability value, it is determined the each sensor node is selected as the sensor node(S150~S170).
