WebCSMA-CA stands for Carrier Sense Multiple Access with Collision Avoidance. The idea here is to avoid collision rather than allowing it to occur. This is done using RTS/CTS signaling mechanism and NAV (Network Allocation Vector). This is shown in the figure-3. Figure:3 CSMA-CA . Following steps are followed in CSMA/CA protocol: • Sender node ... WebWould CSMA/CA without RTS/CTS solve this problem (justify your answer)? (Reply typed and with all the details. thanks ). Question : What is the problem of the exposed terminal and how the Can CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance) with the RTS/CTS (Request To Send/Clear To Send) mechanism alleviate this problem?

The RTS, CTS and ACK frame headers all contain a frame control field (two bytes of metadata flags), duration field, a field for the receiver MAC address, and a frame check sequence. Additionally, an RTS frame contains the transmitter's MAC address. This protocol was designed under the assumption that all nodes have the same transmission ranges, and does not solve the hidden terminal problem.
