<p>A radio communication system, which employs an ad hoc communication method, can ensure information reachability of broadcast communication between terminals. For example, a radio communication terminal (101), which is the first to participate in a cluster, serves as a cluster master and periodically distributes, through the broadcast communication, cluster information comprising the terminal identifiers of the cluster-participant radio communication terminals including itself. For example, in a case where a radio communication terminal (102) participates in the cluster for the first time, the radio communication terminal (102) receives the cluster information, and performs a unicast communication with each of all the participant radio communication terminals identified by the cluster information, and participates in the cluster if the communication reachability between the radio communication terminal (102) is ensured and each of the other participant radio communication terminals, whereby the radio communication terminal (102) can perform a unicast communication and a broadcast communication with any of the other participant radio communication terminals.</p> |
