Data Reliability Evaluation System Of Wireless Sensor Network Considering Disturbance

Wireless Sensor Networks(WSN,Wireless Sensor Networks)is a network structure with information processing and communication capabilities independently built by a number of sensor nodes with self-organizing combination rules.As a bridge for users to grasp the state of the environment,its main function is to collect and process the object information in real time,and transmit it to the user to assist the user in completing various tasks.As a brand-new information acquisition and processing technology,it has broad application prospects and high application value in many fields.However,many fields generally have high requirements for information accuracy,which has derived many categories of research on the accuracy of information collection of wireless sensor networks and the reliability of collected information.In the current research,how to efficiently and reliably arrange A large number of domestic and foreign scholars have done sufficient research on wireless sensor networks and information transmission,and the technology has become mature.However,there are relatively few papers on the reliability analysis of the information collected by the equipment,and there are such things as complex information,The difficulty of label data integration and other issues,the limitations of the proposed technology are obvious,so the reliability of sensor data has become a key to increasing attention.In the research on the reliability of sensor network data,the accuracy of information collection and the anti-interference ability of the network are very important,making sensor reliability assessment technology an important topic in the research of sensor network security.Based on the introduction of sensor network reliability analysis technology,this paper analyzes the various problems that still exist,and combines the characteristics and requirements of sensor network itself,and focuses on the research of the reliability analysis scheme of sensor network under disturbance.Based on the idea of making full use of data changes to reflect the state of sensors,this paper takes the actual monitoring data of wireless sensor networks as the research object,extracts features from wireless sensor network data,and selects the time correlation and spatial correlation of the measured environmental data as reliability indicators.A data reliability evaluation model for wireless sensor networks based on Evidential reasoning rule(ER)is proposed.The model adopts the coefficient of variation method and the distance-based method to determine the weight and reliability of the evaluation index,and uses the rule-based method to unify the index data into a confidence distribution form,and uses the evidence reasoning rules to fuse the index and parameters to obtain the wireless sensor network data Reliability status.Later,the idea of disturbance analysis was added,and the evidence reasoning rules were combined with the disturbance analysis method,and a wireless sensor network data reliability evaluation model considering disturbance was proposed.It is devoted to analyzing the adaptability of sensor networks to different disturbance environments.The experimental results show that,and Compared with the existing schemes,this scheme can effectively evaluate the influence of disturbance factors on wireless sensor networks.
