Security In Wireless Sensor Network Using Key Pre-Distribution Scheme

The Wireless sensor network communication can be captured easily, therefore there is a need for security. To achieve security in wireless sensor network, key predistribution is essential. Key pre-distribution is a method of distribution of keys onto the nodes before deployment. Key pre-distribution schemes have been developed for the better maintenance of key management in wireless sensor network. Each and every sensor node in the network was provided a key, the data will be transmitted between two nodes only if the key matches between two nodes. In this paper, an attempt was carried out to find the malicious nodes in the network. After finding the route in network, an attempt to find out whether there is any malicious nodes present in the network. If any malicious node is identified in the route, then it is
