Embodiment Construction
[0020] The present invention proposes an adaptive scanning rate method, which enables the system to adjust the scanning rate according to the current channel state while satisfying the key bit generation rate, so that the scanning efficiency is higher, so that the utilization rate of network resources is higher. The following is combined with the accompanying drawings and Examples further illustrate the present invention.
[0021] In this embodiment, the controller adopts a PID controller, such as figure 1 Shown, the workflow of the present invention is as follows:
[0022] The working process of the adaptive wireless channel state scanning method of the present invention is as follows:
[0023] Step 1, first preset the initial value of the scan rate between the two wireless communication nodes, and initialize the monitoring process TCPDUMP of the master node;
[0024] Step 2, the master node starts to send the ICMP PING packet, and utilizes the TCPDUMP monitoring process to...
