Hidden station problem in wlan
WebIn such a case, if one station wants to transmit data, there is a fear of collision from the other station i.e. ‘hidden node’. iii. To solve this problem, 802.11 specify an optional ‘request to send/clear to send (RTS/CTS)’ protocol at the MAC layer. iv. With this feature, the station which wants to transmits, transmits an RTS and waits ... Web5.4.7 Exposed Nodes. Unfortunately, the opposite problem to hidden nodes also occurs. Many times, especially in dense networks, the protocol or carrier sense causes devices that could transmit successfully to defer instead. This is called the exposed node problem, because nodes are exposed to being blocked when they need not be.
