<p><P>PROBLEM TO BE SOLVED: To provide a communication apparatus where a plurality of elements relay a signal to transmit the signal without forming separate wiring to each element. <P>SOLUTION: The communication apparatus is provided with a plurality of the communication elements distributed separately. Each communication element stores its coordinates in a space. The communication distance of each communication element is set to a distance within which each communication element can make local communication with other communication elements located around it, and a signal can be transmitted sequentially among the communication elements through the local communication up to a target communication element. The coordinates of a sender communication element and coordinates of a destination communication element are described in the transmitted signal and each communication element discriminates whether the communication element is located on a path tying the sender communication element and the destination communication element. <P>COPYRIGHT: (C)2004,JPO</p> |
