In order to improve the secure connectivity and expansibility of static wireless sensor networks, decrease the memory costs of sensor nodes, an efficient hexagon-based key pre-distribution scheme is put forward by employing the ideas of the grouping key management and secret binding. In this scheme, the process of establishing pair-wise keys for neighboring nodes in the network is limited in the beginning of the network deployment and when adding new sensor nodes into the network, the process of establishing pair-wise keys for the new nodes and their neighbors needs to be verified by the base-station.
