Secure Data Transmission with Hierarchical Clustering

Security in wireless sensor networks is currently provided exclusively through symmetric key cryptography. In this paper we show that the implementations of traditional cryptography is not enough to provide complete secure transmission over the wireless sensor networks. Here, we are going to discuss the drawbacks of the conventional way of routing and try to implement the Asymmetric key cryptography with few enhancement of using alternate sensor node in hierarchical clustering. The combination of IBS signature with multi-hop planner model in hierarchical clustering helps in reducing the impact of frequent node dies and its causes.
