Wireless Sensor Networks (WSNs) consists of a large number of tiny autonomous devices called sensors which are vulnerable to security threats. Heterogeneous Wireless Sensor Networks consists of two types of nodes L1 and L2 that employees Unbalanced Key Distribution Scheme to ensure enhanced security. In this paper, the concept of Link Strength is utilized, which determines the path to be selected for secure routing. Our Keymatches Constrained Secure Routing(KCSR) algorithm provides the flexibility to choose secure path and then route the data accordingly. In this approach, secure and stable paths are chosen for communication. Simulation results show that the proposed algorithm yields better results emphasizing security when compared with earlier works.
