| Research Abstract |
Limiting the application in a radio communication system within feedback control, it was shown that beyond cognitive radio is realizable, which can understand not only the physical environment of the radio channel but also the semantic environment of the application. A carrier sense multiple access (CSMA) scheme was proposed, which estimates the importance of packet and controls the back-off time according the priority of the packet determined by the estimated importance. The performance of the proposed CSMA scheme was evaluated by computer simulation, assuming a situation where there were several wireless systems controlling rotational inverted pendulums.
