Abstract
In this paper, the secrecy performance of cooperative networks with jamming signals of eavesdroppers are studied under the impacts of unreliable backhaul networks. By proposing a two-phase transmitter/relay selection scheme, the desired signal-to-noise ratio (SNR) of relays is maximized by selected the best transmitter, meanwhile, the jamming signal-to-interference-plus-noise ratio (SINR) of the eavesdroppers is minimized by selected the best relay. The secrecy outage probability is derived in closed-form expressions by following some useful lemmas and theorems. Furthermore, the analysis of asymptotic secrecy outage probability is also performed to explicitly reveal the impacts of unreliable backhaul links on the secrecy performance. By the impact of imperfect backhaul links, the diversity gain is limited as shown in our results.
