N2 - The 5G wireless networks will support massive connectivity mainly due to device-to-device communications. An enabling technology for device-to-device links is the dynamical spectrum access. The devices, which are equipped with cognitive radios, are to be allowed to reuse spectrum occupied by cellular links in an opportunistic manner [1]. The dynamical spectrum availability makes cognitive users switch between channels. Switching leads to communication overhead, delay, and energy consumption. The performance degrades even more in the presence of security threats. It is important to countermeasure security threats while meeting a desired quality of service. In this paper, we analytically model the impact of spectrum dynamics on the performance of mobile cognitive users in the presence of cognitive jammers. The spectrum occupancy is modeled as a two-state Markov chain. Our contribution is proposing a pseudorandom time hopping technique to countermeasure jamming. We achieve an analytical solution of jamming probability, switching and error probability. Based on our findings, our proposed technique out performs the frequency hopping anti-jamming technique.
