| Popis: | Considering a wireless social network, we investigate a cooperative jamming scheme based on the space power synthesis with unknown channel state information (CSI) of eavesdroppers. In particular, we provide a multiple jammers-based anti-eavesdropping model and formulate it by a superposition principle of various jamming signals in a free space. Based on the model, we analyze the superimposed effects of jammers with different locations in a fixed area, and then present corresponding jamming schemes to minimize synthetic jamming power at a legitimate receiver but satisfying basic interference in other locations. Furthermore, we also provide power allocation schemes to maximize the worst-case secrecy rate of a legitimate receiver. Numerical simulation results demonstrate that the secrecy performance of our cooperative jamming schemes can satisfy the requirements of secure transmission in a fixed area. Besides, our proposed power allocation schemes can further improve secrecy rate without known exact CSI of eavesdroppers. |
