A group-based deterministic key pre-distribution scheme for wireless sensor network

摘要

In this paper, we present a deterministic key pre-distribution scheme for wireless sensor network using combinatorial designs adapting a group- and cluster-based approach. Clusters are formed by taking a collection of nodes, and those clusters are further taken collectively to form groups. Three types of communications enable us to achieve connectivity of desired level. Our scheme provides better resilience (both in case of node and links) as compared to some other schemes, while keeping the number of secret keys to be stored at each node significantly less.
