ABSTRACT:
A wireless multi-hop network is formed by exchanging a control message including a HELLO message and a topology message between a plurality of communication terminals. A communication terminal adjusts a control message transmission interval so as to reduce the control load according to its movement state and transmits a control message at a longer transmission interval as the movement becomes smaller. Moreover, when link information is updated, the communication terminal includes the sequence number of the HELLO message in the topology message transmitted. Thus, it is possible to realize stable communication in accordance with a movement characteristic with a small message transmission frequency.
