MOBILE AGENT BASED DIGITAL CITY SPATIAL INFORMATION SERVICE
This work is supported by the Special Funds For Major State Basic Research Project coded G2000077900.
Mobile Agent technology is a beneficial technology for conceptualizing, designing, and implementing distributed web software systems. Digital City Spatial Information Service System is a typical distributed system with huge volume of spatial data to acquire and analyze. In this article, we firstly introduce the Mobile Agent technology and the importance to implement Digital City Spatial Information Service System. Then the necessities for Mobile Agent technology to implement Digital City Spatial Information Service were described from two aspects, i.e. the advantage of Mobile Agent technology and the need of Digital City Spatial Information Service System. The architecture of Mobile Agent based Digital City Spatial Information Service we put forward was introduced in the next part. Lastly we expatiated the realization of Mobile Agent based Digital City Spatial Information Service System using Java and DCOM technology. A conclusion and future works on the Mobile Agent based Digital City Spatial Information Service is also discussed.
