安全双向中继通信中友好干扰节点的功率分配
Power allocation for secure two-way relay networks with friendly jammers
摘要
Abstract
This paper studies the secure information exchange for two-way relay transmission with friendly jammers. The two models, where the eavesdropper is relay node and the eavesdropper is another node are both considered. Our goal is to seek the power allocation for the friendly jammers to minimize the total power of them such that the secrecy of the information exchange between the two sources can be protected. To this end, we formulate two optimization problems for the two models, and prove both of the two models are linear programming. Simulation results show that, via optimal design for the power of friend jammers, physical layer secrecy can be greatly improved.关键词
