A Combinational Approach Using Matrix Based Pairwise Key Establishment and Post Deployment Approach in Wireless Sensor Networks

Dinesh Dhakar, Ravi Khatri

Abstract: Key distribution schemes ahs always played a pivotal role in the security of wireless sensor networks. In this research work we focus mainly on the security aspect of WSN. We have developed a modified key distribution scheme which uses the concepts of post as well as pre distribution scheme and thus hs proved to be a better alternative then the rest of two schemes. Simulation study has been carried out using matlab. The effort turned out to be fruitful s our modified scheme showed less dead nodes per round of data transfer as compared to post deployment scheme.
