POINT-TO-POINT COMMUNICATION METHOD IN A WIRELESS SENSOR NETWORK AND METHODS OF DRIVING COORDINATORS AND COMMUNICATION DEVICES IN THE WIRELESS SENSOR NETWORK

摘要

PURPOSE: A point-to-point communication method in a wireless sensor network and a method for driving a coordinator and a communication device in the wireless sensor network are provided to stably keep security without using a master key. CONSTITUTION: Clusters perform an initialization process(S500). Nodes generate each authentication information. The nodes exchange the authentication information each other. The nodes authenticate each other(S502). The nodes generate each link key generation information. The nodes generate a link key by exchanging the link key generation information(S504). The nodes communicate each by the generated link key(S506).
