In the WSN,the node location technology is a basic function to guarantee the effectiveness of other application,and the positioning process can be divided into two stages:distance estimation and position calculation.This paper introduces three algorithms of distance estimation:Sum-Dist,DV-Hop,and Euclidean,and simulates them in Matlab.The result shows that in the response of the environment all the algorithms perform well and can be further improved.

Key words: wireless sensor network;distance estimation;sum-dist;DV-Hop;euclidean
