[Tinyos-help] time to turn on/off Radio CC2420

Hi all. Sorry for my frequent questions. I'm a student of Informatic Engeenering of University of Pisa. I'm working with TmoteSky motes and TinyOs 2.x on cygwin. I founded a difference between my tossim simulation and realt tests with motes. In Tossim simulation the average message transmission

No the radio is not turned off by default after sending every message. Even if you have defined LOW_POWER_LISTENING, the radio is turned on and off regularly maintaining a duty cycle. I dont know what RxTxDelay is. It had no mention in the CC2420 datasheet. And I tested experimentally the radio

thanks for your answer. When i say RxTxDelay I mean the amount of time the radio takes to change from RX to TX mode (or vice versa). Theorically ,after sending a message, the radio should turn from Ttransfer mode to Receive mode, and then (when it must transmit a message) turn from Receive mode
