On the other hand these can bring a problem such as MAC-deadlock, hidden and exposed terminal problem. 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. solby christiansdóttir

WebB and C will be utilizing CSMA/CA. If one starts transmitting first, the other will back off. If both do happen to transmit at the same time, there should still be no problem in this case. A cannot see the transmission from C (the signal is so weak as to be background noise), and as such should only see the RTS from B. The same is true for D.

WebFeb 20, 2024 · The situation is initially the same as with the hidden station problem: one station is in the middle of two other stations so that they cannot reach each other. One of the two devices now wants to send data to the station in the middle. All accessible nodes receive the CTS frame that stops them from broadcasting. WebJul 4, 2024 · The exposed terminal problem occurs when two nodes (in this case B & C) cause excessive delays in each other due to the inclusion of mechanisms (e.g. carrier-sense based collision avoidance, RTS/CTS schemes) to avoid the hidden node problem. This is a result of the trade-off made to improve performance in the hidden node situation.
