In this paper, combinatorial design followed by randomized merging strategy is applied to
key pre-distribution in sensor nodes. A transversal design is used to construct a (v, b, r, k)
configuration and then randomly selected blocks are merged to form the sensor nodes. We
present detailed mathematical analysis of the number of nodes, number of keys per node
and the probability that a link gets affected if certain number of nodes are compromised. The
technique is tunable to user requirements and it also compares favourably with state of the …
