摘　　要：对于结构复杂多跳无线传感器网络物理层安全性能优化时需考虑组合窃听问题。为了提高无线传感器网络(WSN)安全路由安全性,设计了一种基于功率分配算法的WSN安全路由连接概率优化(JPASR)方法。定端到端最低功率,路由方案及功率分配具有分布式特征,选取优化求解方式。研究结果表明:路由安全连接概率在网络规模增大时显著提高,形成的安全路由数量增大。相比SR算法、FA算法,JPASR算法安全性在固定网络规模时均更高。FA和SR算法路由安全连接概率在提高窃听者密度下持续降低,调整功率及窃听情况有效规避可应用JPASR算法实现。该研究有助于提高无线网络传输效率,具有很好的实际推广价值。The combinatorial eavesdropping problem should be considered when optimizing the security performance of the physical layer of the complex multi-hop wireless sensor network.In order to improve the secure routing security of wireless sensor networks(WSN),a WSN secure routing connection probability optimization(JPASR)method based on power allocation algorithm is designed.The minimum power from end to end is determined,the routing scheme and power distribution have distributed characteristics,and the optimal solution is selected.The results show that the probability of routing secure connection increases significantly and the number of secure routes increases with the increase of network size.Compared with SR algorithm and FA algorithm,JPASR algorithm has higher security in fixed network scale.With the increase of eavesdropper density,the probability of secure connection of FA and SR algorithms decreases continuously.JPASR algorithm can be used to adjust the power and effectively avoid eavesdroppers.This research is helpful to improve the transmission efficiency of wireless network and has good practical popularization value.
