COMMUNICATION CONTROL DEVICE, COMMUNICATION DEVICE, RADIO FRAME COLLISION AVOIDANCE METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a method for avoiding, in the time region, radio wave interference between different radio communication systems using the same frequency band.SOLUTION: A communication control device estimates reception time of a subsequent data frame on the basis of data frame reception time in a radio sensor network, estimates subsequent management frame creation time on the basis of management frame creation time, i.e. creation time of a management frame to give notice of the existence of a radio network operating at the same frequency as the radio sensor network, and changes the frame transmission interval of a radio network in the management frame in the radio network at the estimated subsequent management frame creation time. The subsequent management frame creation time to change the frame transmission interval is management frame creation time right before the estimated subsequent data frame reception time.SELECTED DRAWING: Figure 4
