Optimized Cluster Head and Secret Key Comparison based Secure Routing in WSN

Manoj Kumar and Diwakar Bhardwaj

In Wireless Sensor Network (WSN), the field information is sensed by tons small sensors. The sensors having restricted amount of resources. The sensed information must be conveyed to Base Station in an efficient way to enhance the lifetime of a network. One of the way to achieve this is to cluster the sensor nodes. For WSN, a new energy efficient threshold based routing protocol (ET-LEACH) is introduced in the existing work. The Head of the cluster receives the sensed information and aggregates it. The aggregated data in forwarded to the base station. The network abnormalities may degrade the performance of a WSN. Black-hole and misdirection attacks are most commonly known abnormality. To overcome this issue in this work, Secret Key Comparison [SKC] method is proposed in WSN. SKC method is proposed that facilitates deployment to prevent attacks. The SKC is a dynamic method and attacks are detected with high accuracy. In WSN, intrusion detection system plays major role. A security application requires it. The selection of optimum cluster head in the proposed work is performed by an Enhanced Grey Wolf Optimizer (EGWO) algorithm. Network’s data transmission as well as the throughput can be improved by this proposed method.
