A Secure Data Aggregation Technique for Wireless Sensor Networks Using Iterative Filtering

Jyothi R, Nagaraj G Cholli


Wireless sensor system are accumulation of sensor hubs which send the detected information to sink hub. As sensor hubs are constrained to computational power and vitality asset, a vitality proficient usage of assets are basic keeping in mind the end goal to utilize organize for longer length. Hence data traffic inside network and large amount of data sending to base station need to be reduced. The main goal of data aggregation is to enhance the network life time by gathering an aggregate data in an energy efficient manner. Iterative Filtering algorithm are more reliable and efficient compared to existing method and it provides the way for aggregating the data at secure level and data trustworthiness. In order to strengthen security levels at cluster head cryptographic algorithm such as RSA algorithm is used to encrypt the aggregated data by   using public key and decrypt data at base station by using its own private key. Where this method is responsible for securing the information that is aggregated at cluster head and also secures the information passed through the networks. The simulation results shows that proposed method consumes less computation time, data transmitting, high security and   has a good storage capacity than compared to existing algorithm.
