False Data Detection in Wireless Network Using Dynamic Security Protocol
In the Wireless sensor networks often consists of a large number of low-cost sensor nodes that have strictly limited sensing, computation, and communication capabilities. The security of wireless sensor networks is a challenging problem in the process of data aggregation. As data are send though sensor network confidentiality plays and important role between source and destination. Secure data aggregation is proposed to enhance the data security of wireless sensor networks. In wireless sensor networks, compromised sensor nodes can inject false data during both data aggregation and data forwarding. The existing false data detection techniques consider false data injections during data forwarding only and do not allow any change on the data by data aggregation.
