摘　　要：针对采用传统中继转发协议的协作中继网络安全中断性能较差问题,文章基于随机几何理论,提出一种基于修改转发协议的中继协作安全传输方案。首先,建立无线协作中继网络模型,在窃听者合谋的场景下,采用最优中继选择策略,推导网络的安全中断概率,并进行仿真实验,分析各项参数对网络安全性能的影响。仿真结果表明,与译码转发、随机转发协议相比,修改转发协议能有效提高协作网络的安全中断性能。Aiming at the problem of poor network security performance of cooperative relay using traditional relay forwarding protocol,a scheme based on random geometry to assist information security transmission by relay nodes using modify-and-forward protocol is proposed.Firstly,a wireless cooperative relay network model is established.In the scenario of collusion of eavesdroppers,the optimal relay selection strategy is used to derive the secrecy outage probability of the wireless relay network,and simulation experiments are carried out to analyze the influence of various parameters on network security performance.The simulation results show that compared with the decode-and-forward and random-and-forward protocols,modify-and-forward can effectively improve the security of the network.
