Hidden station problem in wlan

WebHidden Station Problem/ Hidden Terminal Problem in WLAN. In WLAN, when two or more stations who are out of range with each other or unknown about the presence of each other send data at the same time, simultaneously to the common station and it leads to the collision at the common station side.

WebThis will cause a station to not be able to 'hear' another station's broadcast. This is the so-called ' hidden node ', or 'hidden station' problem. [6] Devices utilizing 802.11 based standards can enjoy the benefits of collision avoidance (RTS / CTS handshake, also Point coordination function ), although they do not do so by default. WebBasic Service Set. A Basic Service Set (BSS) forms an ad hoc self-contained network with station-to-station traffic flowing directly, receiving data transmitted by another station, and only filtering traffic based on the MAC address of the receiver (see Figure 5-3 ).
