Node 2 and Node 5, which are neither transmitter nor receiver, set NAV, at the reception of RTS or CTS.
The nodes are prohibited from transmitting frames during the NAV period.
The data frame transmission from Node 3 to Node 4 is successful without the hidden terminal problem.
In addition, the RTS transmissions from Node 1 to Node 2 are ignored during the NAV period of Node 2.
Although the RTS/CTS mechanism can solve the hidden terminal problem, the overhead of RTS/CTS control packets increases.
