Secure Data Aggregation Using Multi objective Metaheuristic Approach for WSN

Wireless Sensor Network is consisting of group of sensor nodes which are able to sense data and to convey sensed information to the base station. Sensor nodes have finite energy and finite memory. For improving the life of sensor node it is essential to minimize the communication process. Data Aggregation is the useful method for extending the life and minimizing communication. Data aggregation combines the data from various nodes and summarizes the data. Sensor nodes convey aggregated data using wireless medium Sensor nodes are placed in the hostile and inaccessible areas the security is necessary factor. There is a possibility of attacks for this confidentiality integrity of data is necessary. So security is required for data aggregation for reliable data. This paper discusses the Multiobjective optimization and Metaheuristic approach to provide secure data aggregation.
