<P>PROBLEM TO BE SOLVED: To implement operation in a beacon mode by avoiding collision of beacon signals including control information in a multihop network having a hierarchical structure. <P>SOLUTION: A radio communication terminal having a function converting each address of the plurality of radio communication terminals into a router number that is a value larger than a router number given to the radio communication terminal in an upper hierarchy connected in series to the radio communication terminal and is unique in a radio communication system: receives a beacon signal including the address given to an upper hierarchy communication terminal from the upper hierarchy communication terminal that is the radio communication terminal in a next above hierarchy in a hierarchical structure; calculates timing, at which its own terminal outputs the beacon without overlapping with that of another radio communication terminal, on the basis of the difference between the router number converted based on the address included in the received beacon signal and the router number converted based on the unique address given to its own terminal; and transmits the beacon signal including its own address to a radio communication terminal in a lower hierarchy according to the calculated timing. <P>COPYRIGHT: (C)2012,JPO&INPIT |
