Attacking Massive MIMO Cognitive Radio Networks by Optimized Jamming

Massive multiple-input multiple-output (MaMIMO) and cognitive radio networks (CRNs) are two promising technologies for improving spectral 2 Pc. Sectional efficiency of next-generation wireless communication networks.In this paper, we investigate the problem of physical layer security in the networks that jointly use both technologies, named MaMIMO-CRN.Specifically, to investigate the vulnerability of this network, we design an optimized attacking scenario to MaMIMO-CRNs by a jammer.For having the most adversary effect on the uplink transmission of the legitimate MaMIMO-CRN, we propose an efficient method for power allocation of the jammer.

The legitimate network consists of a training and a data transmission phase, and both of these phases are attacked by the California Poppy Seed jammer using an optimized power split between them.The resulting power allocation problem is non-convex.We thus propose three different efficient methods for solving this problem, and we show that under some assumptions, a closed-form solution can also be obtained.Our results show the vulnerability of the MaMIMO-CRN to an optimized jammer.

It is also shown that increasing the number of antennas at the legitimate network does not improve the security of the network.
