A CLUSTERING ROUTING SYSTEM AND METHOD FOR WIRELESS SENSOR NETWORKS USING SENSOR NODES' ENERGY AND DISTANCE

摘要

A clustering routing method for energy and distance of a wireless sensor network and a device thereof are provided to make a size of a cluster small by increasing selection probability of a cluster head according to a distance to a data collecting device, thereby realizing uniform energy consumption of the cluster head. Each sensor node determines whether it is selected as a cluster head by probability having a bigger value as it is farther from a collecting device(S11). A sensor node which is not selected as a cluster head selects one among the selected cluster heads(S12). The sensor node transmits sensing information by the selected cluster head and the cluster head merges the sensing information and transmits it to a data collection device(S13).
