<P>PROBLEM TO BE SOLVED: To prevent cutoff of communication when a communication path is switched over to a redundant path, and to restrain a communication band and power consumption for confirming the redundant path, in a radio multihop communication system. <P>SOLUTION: When transmitting a data signal to a radio communication device of a transmission destination by radio multihop communication via a first route, this radio communication device transmits a signa for determining whether communication with the radio communication device of the transmission destination by radio multihop communication via a second route is possible to the radio communication device of the transmission destination by the radio multihop communication via the second route. <P>COPYRIGHT: (C)2011,JPO&INPIT |
