RELIABLE DATA AGGREGATION INCLUDING SECURITY BASED ON AES AND FUNCTIONAL REPUTATION

The wireless sensor network has an important role in the field of measurement and instrumentation. The many research activities on the WSN are going on for reliable and economic data communication. One of the important aspect in the WSN is energy efficient communication. In this regards, the cluster based protocol for data communication has become a standard choice for data communication. For this protocol , d ata aggregation for sensor data has been used in WSN to save the energy of cluster head. Security and trust are fundamental challenges in deployment of this technique in large wireless sensor networks. In this paper, the function reputation is used to iden tify the trustworthiness of the node and cluster head. Along with this, advanced encryption standard (AES) is compare with conventional method for secure data transmission. The reputation value, normalized correlation coefficient and time consumption are t he parameters which are used in this paper for performance analysis
