Web9 de mar. de 2024 · Exposed Terminal Problem In wireless LAN (local area network) communication, the exposed terminal problem is a frequent difficulty. It happens when a wireless node cannot transfer data because another node that is outside its communication range is sending data to another node that is inside it. WebIn wireless networks, the exposed node problem occurs when a node is prevented from sending packets to other nodes because of co-channel interference with a neighboring transmitter. Consider an example of four nodes labeled R1, S1, S2, and R2, where the two receivers (R1, R2) are out of range of each other, yet the two transmitters (S1, S2) in the … WebA carrier sense multiple access with collision avoidance (CSMA/CA) is an access protocol of wireless LAN (WLAN).
