A system based on mobile agents for tracking objects in a location-dependent query processing environment

Nowadays the number of mobile devices is increasing rapidly. However there is a lack of data services that can be efficiently performed in mobile computing environments. The main reason is that many well-known techniques have to be adapted to the new environment. Particularly, the processing of location-dependent queries is still a subject of research. In this paper we introduce an approach to deal with location-dependent queries posed in mobile environments. A decentralized solution is proposed using mobile agents, which also help in the optimization of the communication effort.
