| Abstract: | A self-adaptive LBS is supposed to choose positioning methods and to provide proper services according to the user＇s conditions and requirements. The paper first gives a brief introduction about Grid technology and LBS architecture. Then it analyzes several charac- teristics of self-adaptive LBS, including self adaptation of positioning, self adaptation of service content, and self adaptation of service quality. Finally, it gives the architecture of self-adaptive LBS and its components based on Grid. |
