干扰攻击量化评估下的MHWN多路径优化方法

在实际多跳无线网络（MHWN）中，由于无线信道的开放性，不可避免地面对恶意干扰的攻击。由于多路径技术固有的空间分集能力，在抗干扰设计中有着天然的优势。传统的方法多是基于干扰存在二元性进行多路径的设计，但由于干扰的智能性不断提高，其无法实现多路径路由的优化传输。为了提高抗干扰效果，提出了一种基于干扰评估的动态多路径优化方法，即通过实现量化评估干扰的方法实现业务动态路由优化分配，仿真模拟结果表明该方法可以有效提高MHWN可靠传输性能。

MHWN MULTIPATH OPTIMIZATION BASED ON JAMMING QUANTITATIVE EVALUATION

In real multi-hop wireless networks (MHWN), due to the openness of the wireless channel, it is inevitable to face attacks from malicious jammers. To combat jamming, multipath is widely used for its natural advantage in space diversity. However, traditional methods are mostly based on the existence of jammer. Due to the continuous improvement of the intelligence of jammers, it is impossible to achieve optimal transmission. In order to improve the anti-jamming effect, a dynamic multi-path optimization method based on jamming quantification is proposed, that is, dynamic routing distribution of services by the method of quantitatively evaluating jamming risk. Simulation results show that this method can effectively improve the reliable transmission performance of MHWN.
