These nodes are known as hidden terminals. He transmission range of access point A reaches at B, but not at access point C, similarly transmission range of access point C reaches B, but not at A. In a formal way hidden terminals are nodes in a wireless network that are out of range of other node or a collection of nodes.Ĭonsider the scenario of wireless networking with three wireless devices(e.g. This situation leads the difficulties in medium access control sub-layer over wireless networking.
The hidden terminal problem occurs when a terminal is visible from a wireless access point (APs), but not from other nodes communicating with AP. medium access control (MAC) nodes must be organized in decentralized manner. A wireless network with lack of centralized control entity, sharing of wireless bandwidth among network access nodes i.e.
