Key Distribution Scheme for Hierarchical Cluster Wireless Sensor Network
In Wireless Sensor Networks (WSNs), key management is one of the vital aspects of security. Since sensor networks suffer from the resource constraints like inadequate memory space, connectivity, resiliency, communication overhead, key pre distribution scheme be supposed to need a smaller amount memory space as likely as supporting strong security power, i.e., high resilience against node capture. A random-key pre distribution scheme has professional explanation for distribution keys between sensor nodes. In this paper propose new key distribution which is based on stated based, signal range and clustering heterogeneous sensor nodes.
