A NOVEL HERMITIAN UNITAL BASED KEY PREDISTRIBUTION SCHEME

Network Scalability became a major concern these days for Wireless Sensor Networks because of their resource constrained nature and increasing number of applications which need to satisfy various communicational and computational requirements. Many key predistribution schemes have been designed to achieve a significant trade-off between energy consumption and scalability of network, but which scheme is more efficient is still debatable. Unital design in combinatorial mathematics is a novel technique which can be used for key predistribution is WSN's. This paper presents a novel key predistribution scheme based on this unital design. The proposed scheme is compared with several other existing predistribution schemes and the performance results obtained shows better trade-off between energy consumption and scalability than many other schemes.
