COMMUNICATION DEVICE, COMMUNICATION METHOD, AND PROGRAM

PROBLEM TO BE SOLVED: To effectively resolve a hidden terminal problem while achieving both of low power consumption and a real-time property.SOLUTION: When a reception block 101 receives a wake-up frame from another node, an upper layer processing block 105 puts the reception block into a sleep mode until the time designated by the wake-up frame to prevent it from receiving any frames so that any collisions are prevented from occurring hereafter. Besides, even if collisions are occurring when starting the reception, the reception of wake-up frames is continued until resolution of the collisions, only a wake-up frame from a node which is continuing the transmission to the last is received, and the reception block is put into the sleep mode until the time designated by the wake-up frame, so that any collisions are prevented from occurring hereafter. After that, at the time designated by the wake-up frame, the sleep mode of the reception block 101 is released to receive data frames.
