Probabilistic Optimization Analysis of WSN Secure Routing Connection Based on Power Allocation Algorithm
The combinatorial eavesdropping problem should be considered when optimizing the security per-formance of the physical layer of the complex multi-hop wireless sensor network.In order to improve the secure rou-ting 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 deter-mined,the routing scheme and power distribution have distributed characteristics,and the optimal solution is se-lected.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 pow-er and effectively avoid eavesdroppers.This research is helpful to improve the transmission efficiency of wireless network and has good practical popularization value.
