Integration of mobility into system characterization can complicate system analysis, as characterizing interference in mobile wireless networks is more difficult, especially when the assumption of independence of users’ distributions is relaxed. However, in some practical systems, quite a number of users may be mobile, making the integration of mobility important. In this paper, mobile users’ coverage in cognitive radio networks is investigated under the assumption that primary users are distributed following the Matern hard core process, while secondary users are distributed following the extended Poisson hole process. A relaying based mobility technique was proposed to sustain coverage at any tagged receiver when such receiver is located outside the coverage of its corresponding tagged transmitter. Analyses of outage probability and average throughput were derived in both primary and secondary networks and verified through simulations. The outcomes of numerical results show that the proposed mobility scheme is capable of improving coverage of mobile users in cognitive networks.
