WebIn wireless networks, the exposed node problem occurs when a node is prevented from sending packets to other nodes because of co-channel interference with a neighboring transmitter. Consider an example of four nodes labeled R1, S1, S2, and R2, where the two receivers (R1, R2) are out of range of each other, yet the two transmitters (S1, S2) in the … WebIn a wireless LAN, even if the coverage of the access point (AP) and the mobile terminals are the same, the hidden terminal problem can not be avoided. If the AP and all the mobile terminals have the same coverage with a radius R there will always be terminals in the coverage area of the AP which are hidden to one another. http://www.ijsrp.org/research-paper-1212/ijsrp-p1266.pdf how do you become a member
