Energy Aware Key Pre-Distribution Scheme for Wireless Sensor Networks

Taking the considerations of WSNs application, there is a need of a highly scalable key pre distribution scheme for WSNs. Along with this there needs to be considerations of the limitation of the resources used in WSNs and the key management challenges also. Network scalability, resiliency are the main concerns when designing a key management scheme. Network scalability means, the network should support very large numbers of nodes so that the large network can be deployed. Good secure connectivity and the large network scalability can be implemented using the Unital design theory. Unital is the complete new approach for the WSNs for key management. The basic Unital mappings for the key pre distribution can be used. Along with network scalability there should be good key sharing probability also. Conduction of approximate analysis and simulation and comparison to the existing system can be shown. Also the limitation of storage overheads, Network scalability, Resiliency, network connections are to be considered. Proposed methodology show that the network scalability is enhanced while providing high secure connectivity and other performances also at the same network size. The proposed work reduces the storage overheads also.
