| Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. In wireless
networks, the exposed node problem occurs when a node is prevented from
sending packets to other nodes due to a neighboring transmitter.
Consider an example of 4 nodes labeled R1, S1, S2, and R2, where the two
receivers are out of range of each other, yet the two transmitters in
the middle are in range of each other. Here, if a transmission between
S1 and R1 is taking place, node S2 is prevented from transmitting to R2
as it concludes after carrier sense that it will interfere with the
transmission by its neighbor S1. However note that R2 could still
receive the transmission of S2 without interference because it is out of
range of S1. |
