<p><P>PROBLEM TO BE SOLVED: To provide a means for hopping a receiving communication node in following a receiver moving among a plurality of communication nodes, not received by a single communication node. <P>SOLUTION: A desired communication node by the receiver is discovered by controlling a destination discovering process as means for a communication node used by the receiver to receive communications from others. Communication nodes desired to be discovered as destinations are grouped as a communication node group which can be the first communication node 10 within the moving range or the desired range of the receiver. This group may be geographically distributed and the network addresses may be distributed. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
