In existing network applications, there is a type of terminal that has poor roaming initiative, which is mainly manifested in that it always "sticks" to the AP it initially associated with. Even if the terminal moves far away from the currently associated AP, the signal is weak, and the rate is low, this type of terminal still cannot roam to other neighboring APs with better signals. This type of terminal is called a sticky terminal. Which of the following is a roaming optimization solution for sticky users?
