METHOD FOR EXECUTING DISTRIBUTED VERIFICATION FOR MEASURED DATA IN SENSOR NETWORK AND SYSTEM FOR EXECUTING THE METHOD

摘要

A method for executing distributed verification for measured data in a sensor network and a system for executing the method are provided to divide nodes on a sensor network into plural logical clusters, receive and verify the measured data of sensor nodes included into the same cluster in an aggregator, which exists in each cluster, and transmit the verified measured data to a BS, thereby performing the verification of the distributed measured data to operate the sensor network efficiently. A method for executing distributed verification for measured data in a sensor network comprises the following steps of: verifying measured data received from plural sensor nodes in an aggregator(S301); generating verification request data by using the measured data and transmitting the generated verification request data to a verification node in the aggregator(S302); verifying the aggregator through the verification request data and a predetermined number of sensor nodes in the verification node; transmitting an aggregation result for the measured data from the aggregator to a BS(Base Station) when the aggregator is verified(S304); and verifying the aggregation result in the BS(S305).
