The invention belongs to the technical field of
wireless communication, and discloses a
wireless communication CSMA / CA optimization method based on hardware performance adjustment, and the method comprises the following steps: S1, when a
wireless message is ready to be sent, obtaining a first random time according to the minimum backoff time, carrying out backoff, and then entering a step S2; s2, judging whether a
current channel is idle or not, if not, entering step S3, and if yes, entering step S4; s3, acquiring second random time according to the current window CW, performing back-off according to the second random time, then adjusting the size of the window CW, and returning to the step S2; and S4, carrying out
fixed time PCStime back-off, then reading the
signal value of the
current channel, judging whether the
current channel is idle or not, if not, returning to the step S3, and if yes, ending back-off, preparing to send, and adjusting the size of the window CW. According to the method, a back-off mechanism is improved for hardware performance, the CSMA / CA
algorithm is optimized, and the method is more suitable for the actual purpose of a real
wireless transmission scene.
