Wireless works have great prospect in the applications of military affairs, circumstance observation, disaster relief operation, dangerous area domination, etc. One of the key qualifications for these applications is localization of the targets needed monitoring and work node. And some routing scheme, information work coverage, load balance, topology control, all of which depend on the location information of the nodes works. The information that is collected by the node sensors and transferred to the console makes sense only when it bined with the location information of the node sensors. Information without collecting position is almost of no use. The study for self-positioning of wireless works possesses great significance in the theory and practice, and it will e an important part in the research area. ?? ????!"?????The paper analyzed the localization mode and model with evaluate criterion and classify methods work, which based on the summarize of research into current situation both inside and outside the country, also the system structure of location techniques and solf-hardware work node, following referring the inherent and the wide application value of wireless work. The research mainly introduce several representative arithmetic of Range-free, which have been analyzed, simulated pared, besides, detect the shortage in
