WebMay 1, 2024 · In this paper, we resolve the hidden terminal problem at the phase of AP selection. By default, a new station selects an AP based on the received signal strength (RSSI) of beacons, so that the AP with the best channel condition is chosen. It is well known that this approach results in suboptimal AP selection by ignoring the traffic load of APs.
