Go to your favorite Web site and find out, what is meant by the hidden terminal problem and the exposed terminal problems? Explain clearly, how can you address them?
What will be an ideal response?
Hidden terminal problem occurs when a node other than the receiver is hidden
from the transmitter. This way the node cannot detect any ongoing
communication and may interrupt the data reception at the receivers. In exposed
terminal problem, nodes that are not participating in an ongoing transmission have
to stay idle for some time period before the transmission completes. To address
these issues we have RTS and CTS packets which may help in knowing ongoing
transmissions.
