<p><P>PROBLEM TO BE SOLVED: To provide a technique for properly setting a path to a reference element for a communication elements which are not two-dimensionally uniformly disposed. <P>SOLUTION: In this communication apparatus, the reference element transmits a relative coordinate deciding packet to surrounding communication elements, and upon receiving the relative coordinate deciding packet, each of the communication elements decides its own chain relative coordinate to transmit the relative coordinate deciding packet to the surrounding communication elements, thereby continuously setting relative coordinate data between each communication element and the reference element. The communication element having decided the relative coordinate transmits a relative coordinate deciding packet using itself as a relay element to the surrounding communication elements at a predetermined timing, and each of the communication elements having received the packet acquires a chain relative coordinate in which a path is decided to the reference element through the relay element. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
