WebA significant difference between wired and wireless LANs is the fact that, in general a fully connected topology between the WLAN nodes cannot b assumed. This problem gives rise to ‘hidden’ and ‘exposed’ station problems. Hidden Terminal: As seen in the above problem, the transmission range of A reaches B but not C. 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 …
