- Channel Interference
- --------------------
- The problem of Interference occurs "when a receiver is in range of one transmitting station
- and slightly out-of-range of another transmitting station, but is unable to cleanly receive
- the closer station's signal because of the interfering presence of the other signal."
- In our animation, we show 2 cases :
- Case 1:
- -------
- When 2 nodes are in range of each other
- When these 2 nodes do carrier sense at different times, they detect carrier and the node
- that senses carrier later, backs off, thus avoiding collision at the receiver.
- But if the 2 nodes do carrier sense at the same time, they are not able to detect carrier
- and hence there is a collision at the receiver.
- Case 2 :
- -------
- When 1 node is slightly out of range of the other
- In this case, when both nodes send data to the receiver, some of the packets sent by the node
- closer to the receiver get dropped, because the receiver receives some packets from the node
- slightly out of range.
