The Concentric Clustering Scheme for Efficient Energy Consumption in the Large-Scale Sensor Networks

摘要

The present invention relates to an energy efficient routing method using a concentric form of clustering techniques on large-scale sensor networks . Sensing data routing techniques in a sensor network according to the present invention is a cluster setting step of setting at least one of the first to n-th cluster consisting of concentric sensor node based on the location of the last data collection node; Chain forming step of forming the sensor node in the cluster is set as a chain; Head node selection step of selecting one of the head node formed by the chain-case, the head node must collect sensed data from the sensor nodes forming each chain; The data to be collected through the head node includes a data transmission step of transmitting the data collected by the end node. Thus, the routing scheme using a plurality of chains that are based on a cluster of a plurality of concentric circles can prevent unnecessary transmission of the data to be energy efficient and suitable for large-scale network.
