A Secure Cluster Based En-route Filtering Scheme in Wireless Sensor Networks
Wireless Sensor Networking is one of the most prominent technology that is used in almost all real time applications. WSN is used in the estimat ion of temperature in Cyber Physical Network System(CPNS) where the sensor nodes are deployed in an unsecured environment. In this kind of environment the lifetime of the network , consumption of energy , re-election of cluster head plays an effective role . So, the network lifet ime with limited battery power becomes a problemat ic issue. By selecting the cluster head randomly among the nodes may leads to the issue of battery loss , false data injection attacks. In order to prevent this we make use of Fuzzy logic technique. In fuzzy logic based cluster head election the base station is responsible for the cluster head election because the base station is more powerful than the sensor nodes in terms of power of computing , unlimited supply and storage of power , and memory. So by selecting the most efficient node as the cluster head we can securely forward the data to the base station by using secure algorithms.
