PROBLEM TO BE SOLVED: To provide a communication node system capable of improving security in communication path analysis. SOLUTION: When predetermined data are received (S21), a first relay node updates information on the next node to information on a second relay node which is information on a destination relay node, and updates information on the previous node to information on the first relay node which is itself (S24) of the predetermined data. Then, the predetermined data are transmitted within a communication range (S25). The first relay node further creates first replay data (S26). Namely, the first reply data are constituted of information on a transmission source node as reply destination information, the information on the transmission source node as the reply following node, signal intensity, and the information on the second relay node as information on the destination relay node. Then, the first reply data are transmitted within the communication range (S27). COPYRIGHT: (C)2011,JPO&INPIT |
