Objective: To design a key pre-distribution scheme for a heterogeneous group of sensor nodes with the help of combinatorial design for high resilience against node capture. Methods/Statistical analysis: Methodology used here is based on theory of balanced incomplete block design where a group of BIBD is used for each of the sensor groups and keys are distributed based on the orientation of these groups. Findings: Connectivity, Storage limitation and resilience are evaluated for the proposed scheme. Application/Improvements: Combinatorial design based scheme is proven to be most suitable method among various key pre-distribution schemes. Combinatorial design based scheme distributes keys to the sensor nodes according to Balanced Incomplete Block Design (BIBD). Use of combinatorial design improves the overall performance of the network.
