The purpose of sensor network node localization is to obtain the information about the absolute or relative locations of various kinds of sensor nodes on the plane or in space. In many sensor network application fields, one important issue that users are concerned about is: in what location or area an inappropriate use or detection situation occurs. Sensor network node technology provides vital node location information for a whole network system's obtaining a large amount of detailed and reliable monitoring information. The obtaining of node location information will directly influence the effectiveness of the whole network system, so study on the node localization mechanism and algorithm involved in a wireless sensor network is the key to realizing node localization technology. In this paper, based on wireless sensor network research, a range-free localization mechanism based on DV-Hop localization algorithm is analyzed, with the optimized processing of this algorithm preliminarily realized, with an intuitive understanding of the relationship between nodes and localization errors realized through MATLAB simulation experiment.
