A Simulation Study on Scalable Key Management Scheme for WSN

WSN is sensitive to attacks as it is resource constrained. Network scalability is one of the concerns with respect to-secure key management schemes. Recently Bechkit et al. proposed a key pre-distribution scheme for WSN which is scalable and provides secure connectivity among nodes in WSN. They used unital design theory for key predistribution. Network connectivity, network resiliency, network scalability and storage overhead were the parameters used for the experiments. Influenced by those techniques, in this paper we build a prototype application, a custom simulator that demonstrates the proof of concept. The simulation involves the transmission mechanisms at sender, receiver besides the communication visualization as part of routing process. We made experiments with simulations. Our empirical study reveals that the proposed application is able to demonstrate the secure key pre-distribution process. In future it can be used to implement key pre-distribution scheme in the real world WSN applications.
