The Comparative Analysis of an Efficient Key Pre-Distribution Scheme for Wireless Sensor Networks

The security in wireless sensor network is a burning issue. In this paper, we are showing the comparative analysis of a new pre key distribution scheme with existing scheme of WSN. We will propose a new scalable key management scheme for WSNs. It is also more secure. To design the key management scheme, we will use the unital design theory. We will show that the basic mapping from unitals to key pre-distribution allows us to achieve high network scalability. We propose an enhanced unital design theory based key pre-distribution scheme. It will provide higher scalability. It will also provide a good key sharing probability. The experimental results show that the proposed approach enhances the network scalability while providing high secure connectivity coverage and overall improved performance. It also reduces significantly the storage overhead compared to those of existing solutions.
