This paper focuses on wireless sensor work localization algorithm without distance. This paper on the basis of consulting a large number of relevant literature, were introduced based on wireless sensor work location technology research status at home and abroad, the wireless sensor work positioning technology makes a overall summary. , the thesis summarizes the wireless sensor work positioning systems and algorithms of performance evaluation standard, the classification method, are introduced in recent years, the typical algorithms in this field and the principle and characteristics of system, and has carried on the brief introduction to several of them. Finally, the thesis focus on without ranging from localization algorithm to the study on DV short of the algorithm. Through the simulation experiment of this algorithm in the simulation platform of Matlab, and statistical analysis the influence of various factors on properties of positioning algorithm.
