A wireless multi-hop network communication terminal 11 uses a Hello information suppression function 21 to suppress a part of information included in a Hello message for a given time after start-up or a new neighbor terminal is detected, thereby reducing message length. Further, the communication terminal 11 uses a Hello interval adjustment function 22 to adjust and shorten a Hello interval during the suppression of the Hello message length. After canceling the suppression of the Hello message length, the communication terminal 11 calculates and establishes a second Hello interval that is shorter than the usual one. Furthermore, after canceling the second Hello interval, the communication terminal 11 reestablishes the steady-state Hello interval. In this way, the time required for the route convergence among the communication terminals can be shortened when a large number of communication terminals, which are adjacent to one another in a narrow-band wireless network and existent within a wireless communication range, are started up at the same time or when a new communication terminal is added to the network.
