Friendly-jamming schemes (DFJ and OFJ) are models that can decrease the eavesdropping risk by purposely interfering the network when an unknown user is near the area of the protected area. [ 1 ] [ 19 ] The models are tested by the probability of eavesdrop attacks in a testing environment, and are found that there is a lower probability of ...

FHSS is used to avoid interference, to prevent eavesdropping, and to enable code-division multiple access (CDMA) communications. The frequency band is divided into smaller sub-bands. Signals rapidly change ("hop") their carrier frequencies among the center frequencies of these sub-bands in a determined order.
