DEVICE AND METHOD OF CONTROLLING WIRELESS SENSOR NETWORK BASED ON PACKET MONITORING AND COMPUTER-READABLE MEDIUM HAVING THEREON PROGRAM PERFORMING FUNCTION EMBODYING THE SAME

摘要

An apparatus and a method for controlling a wireless sensor network based on packet monitoring and a computer-readable medium recording a program for implementing the same are provided to recognize the structure of a data packet broadcasted in each node, analyze the data packet, and detect an abnormal pattern, thereby easily monitoring hacking or invasion for each node within the wireless sensor network. A data communication interface unit(210) receives packet data broadcasted on a wireless sensor network having plural sensor nodes(100). A packet data analysis unit(220) analyzes the packet data received from the data communication interface unit. A pattern data storage unit(230) stores pattern data for an abnormal context. An abnormal context determination unit(240) determines the abnormal context of the wireless sensor network on the basis of the analysis determination of the packet data or the pattern data. The wireless sensor network supports zigbee standards. The packet data analysis unit inspects the sequence number of the zigbee standards for the packet data. The abnormal context determination unit determines that the wireless sensor network is in an abnormal state when the sequence number is abnormal.
