Interference causes loss of information. This information loss means loss in packets. Loss in packets means re-transmission in order to pass the information. Re-transmission leads to collision as the qeue of the data to be transmitted gets bigger.
In data transmission when there is interference super impose on your data signal the result will be best explainable by the super heterodyne effect.
In effect some of the data levels will be to low to be interpreted by the equipment causing some bit errors. The same as when the logic levels for TTL is to low, then you will get unpredictable logic output.

When two nodes sends data at same that then Collision occur and data packet become corrupted. So the sender need to re-transmission. The retransmission is energy consumable and unacceptable in Wireless Sensor Network. The researchers are trying to minimize its occurring. CSMA(Carrier Sense Multiple Access) is also used to sense. In WSN, fours things are considered most energy wastage.
1. Idle Listening.
2. Collision.
3. Overhearing.
4. Control Packet Overhead.
These are the hot topic in research now days.
