METHOD FOR GROUPING AMONG SENSOR NODES IN HETEROGENEOUS WIRELESS SENSOR NETWORKS

摘要

The present invention relates to a grouping technique among sensor nodes in a sensor network consisting of a heterogeneous environment of the sensor node that receives a group code from the sensors forming a network management system , extracts the group information for the group of conditions of the conditions included in the group formed code , transmitting the extracted information group to the sink node, the sensor node located in the surrounding detect the signal by the parent , child , and sibling information of the sensor node to the sink node, characterized in that the transmission . According to the present invention , by using a hybrid grouping scheme between the sensor nodes , to reduce battery consumption of a sensor node can perform the remote software upgrade code efficiently .
