It introduced major technique of Location based Service, and develop a LBS system based on Ericsson MPS. It realized how to search self-position and other's position.
The localization of sensor nodes, which is the foundation of the other applications, is to determine self-position using a certain localization scheme, according to the anchor nodes.
