Providing Good Coverage and Secure Connectivity Using Key Pre-Distribution Scheme for Wireless Sensor Networks

Abstract

Now A Days, wireless device networks (WSNs) are more and more utilized in important applications inside many fields as well as military, medical and industrial sectors. Given the sensitivity of those applications, sophisticated security services square measure needed. Key management may be a corner stone for several security services like confidentiality and authentication that are needed to secure communications in WSNs.In existing system, we discover most Rate Of Networked Computation during a Capacitated Network during this they focused only on network capability they didn't about secure connectivity it means that giving security to that information whereas transfer from source to destination. This is often the massive disadvantage in existing system. To overcome this problem we tend to move to proposed model. we propose a new scalable key management scheme for WSNs that provides a good secure connectivity coverage. For this purpose, we tend to make use of the unital design theory. We tend to show that the basic mapping from unitals to key pre-distribution allows us to attain high network scalability. Nonetheless, this naive mapping doesn't guarantee a high key sharing probability. Therefore, we tend to propose an enhanced unital-based key pre-distribution theme providing high network scalability and good key sharing probability approximately lower bounded by 1 ? e?1 ? 0.632. we tend to conduct approximate analysis and simulations and compare our solution to those of existing methods for different criteria like storage overhead, network scalability, network connectivity, average secure path length and network resiliency. Our results show that the proposed approach enhances the network scalability whereas providing high secure property coverage and overall improved performance.
