Node technology has been widely used in wireless sensor networks and is the core of its technology.the accurate location sharing of monitoring events can be realized through correct positioning.At present,in the application process of sensor node positioning technology,first of all,it should be based on ranging(Range-based)positioning technology,and the other is that network positioning technology can be realized without ranging.Through the practical application and comparison of the two technologies,it is found that the application of non-ranging technology is superior to the former in the cost and input of the former.Therefore,in the research of this subject,the positioning technology without ranging is mainly analyzed.Innovative research and application of wire sensor network technology.Firstly,this thesis analyzes and introduces the main concepts of wireless sensor in detail in the search and comparison of literature on a large number of related topics,and according to its historical development time,period and characteristics,emphatically analyzes the structure system of wireless network sensor.Secondly,the evaluation criteria of network self-positioning system and algorithm performance in sensor system are comprehensively studied and analyzed,and combined with effective classification method and corresponding research content,combined with representative methods to measure network sensing distance,the calculation of nodes is analyzed,and the simulation is carried out by fully combining the calculated data.Finally,in the process of in-depth analysis of the data and classification and comparison,the corresponding anchor nodes can be moved with the help of GPS adaptation structure or system,and the corresponding positioning technology can be proposed in the control results of the noise system.Based on RSSI,the feasibility analysis and research of the non-ranging realizable 3D positioning algorithm can be carried out.Through simulation experiments,it is shown that the wireless communication environment can be used and used.According to the comparison between different calculation results and similar algorithms,this thesis selectively puts forward the related strategies to improve the positioning accuracy,and makes the applicable scope of the technology cover any geographical environment.
