Data Integrity Preserved Data Aggregation Technique over Smart grid Communication System

Saranya Alagesan, Mrs.P.Anatha Prabha

Smart grid application is the most concerned application in the real world environment which will generate different power readings in different time periods. This need to be gathered and send to the centralized server for further processing. The single node failure in the smart grid system might lead to entire system failure where the aggregation cannot be performed well. This problem is resolved in the existing work by using the fault tolerance based data aggregation technique where the data can be aggregated even if any of the nodes failed in the system. However data integration becomes the greatest issue in the smart grid system where the data forwarded to the centralized server might get changed in case of corruption. This problem is resolved in the existing work by introducing the recoverable scheme in which data can be recovered even in case of corruption also. This is achieved by comparing with the average aggregated value with all the data that are sensed by the sensors.
