This paper proposes active RFID tag drive by a thermoelectric conversion element by using temperature difference between outside air and human skin. In recent years, energy harvesting techniques have been attracting attention. Powers saving sensors driven by energy harvesting techniques are expected to eliminate maintenance such as battery replacement. Therefore, in this study, the active RFID tags...
In cellular mobile communication systems, radio channels are repeatedly used in order to efficiently use assigned frequency bands. The computation time for the optimization of channel assignment increases with the increase of cell number. This paper presents a group channel assignment method for the optimization and its simulation results. This method utilizes the genetic algorithm (GA). Prior to...
