The error will inevitably appear in triangle location in WSNs (wireless sensor networks), and the analysis of its character is very important for a reliable location algorithm. To research the error in triangle location algorithm, firstly, a triangle location model is set up; secondly, the condition of the minimal error is got based on the analysis of the location model; at last, by analyzing the condition, the law of error’s changing is ab-stracted, and its correctness is validated by some testing. The conclusions in this paper are all proved, and they provide a powerful foundation and support for reliable location algorithm’s research.
