SECURED DATA AGGREGATION USING FIBONACCI NUMBERS AND UNICODE SYMBOLS FOR WSN

Wireless Sensor Network is a combination of one and more nodes basically used for data collection and data aggregation. The collected data is aggregated through a data aggregator and it will be sent to bases station. While data transfer takes place, the intruders sniff the data that are being transmitted from one node to another. In order to prevent data sniffing by the intruder a study is made to prevent data sniffing and data breaching its boundaries. A two-fold cryptographic method is proposed using Fibonacci number and Unicode systems. The proposed method is two-fold viz, converting the normal simple text to secret message ii) convert secret message to Unicode text. The proposed method uses a two-fold security key encryption algorithm for transfer of data in the Wireless sensor networks and a decryption algorithm is also provided to convert back to its normal plain text.
