Detection of dynamic location primary user emulation on mobile cognitive radio networks using USRP

EURASIP Journal on Wireless Communications and Networking

Table 1 PUE classification, adapted from [22, 29, 30]

Classification of the attacker	Category	Definition
Purpose	Selfish	The objective is to use the PU assigned frequency for transmission; it senses the medium to know when there is no PU.
Purpose	Malicious	The objective is to interfere the PU frequency; it sends noise signals in a specific frequency.
Power level	Fixed	Constant predefined power level, regardless of the actual power, the power units and the surrounding radio environment.
Power level	Variable	It adjusts its power according to the estimated power of the PU.
Position	Static	The location does not change in time.
Position	Dynamic	The position changes constantly, making it difficult to search or crawl.
General functionality	Basic	It attacks with a fixed power level at static position at any moment, even in the presence of a primary user.
General functionality	Smart	It attacks when there is no PU, position can be static or dynamic, and it can adapt the power level.
