We propose one deterministic key distribution schemes for wireless sensor networks, where the nodes are deployed in a 3 dimensional grid like structure.We use combinatorial designs for key predistribution in sensor nodes. Here the deplyment region is a 3-D grid. The whole deployment region is divided into smaller cubic zones. The predistribution scheme has the advantage that all nodes within a particular region can communicate with each other directly and nodes which lie in a different regions can communicate via special nodes called agents which have more resources than the general nodes. The number of agents depend upon the construction.
In our key distribution scheme we have used within group key-distribution and one key distribution for inter-group communication. We use one existing key pre-distribution scheme for intra-group communication between nodes and for inter-group communication we use our proposed scheme.
