PROBLEM TO BE SOLVED: To provide a radio communication system that can reduce the collision probability of transmission data when a communication route is constructed, and enables execution of multi-hop communication through a communication route having a small number of hops.SOLUTION: When receiving ACK added with final destination information, a relay machine 30 determines the number of hops at the next stage on the basis of the number of hops contained in the final destination information. When receiving ACK transmitted from another node after the data reception, the relay machine 30 would transmit ACK in which a lower node of a transmission source is added with the final destination information if the number of hops of the final destination information added to the received ACK is not less than the number of hops at the next stage. When receiving ACK transmitted from another node after the data reception, the relay machine 30 would not transmit any ACK if the number of hops of the final destination information added to the above ACK is smaller than the number of hops at the next stage. |
