<p><P>PROBLEM TO BE SOLVED: To provide a communication system in which each node can perform effective communication flexibly, even if there is no management node, while ensuring a sufficient data transmission period. <P>SOLUTION: Each node transits its operating state or operation timing, while reflecting the basic speed of state transition and delivering/receiving a state variable signal representative of its operating state or operation timing. Based on the transition state, time slot of each node is assigned. A node, with a large volume of transmission data, transmits a plurality of types of state variable signals and acts as a plurality of nodes so that it is assigned with a plurality of time slots. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
