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.

Hidden nodes in a wireless network are nodes that are out of range of other nodes or a collection of nodes. Consider a physical star topology with an access point with many nodes surrounding it in a circular fashion: each node is within communication range of the AP, but the nodes cannot communicate with each other. graph apple stock price historyWeb20 de fev. de 2024 · The technical differences between wired and wireless networks also lead to the so-called hidden station problem.
