A mobile agent-based framework for location-based services

A general-purpose framework for building and managing location-aware applications in ubiquitous computing environments is described. The goal of the framework is to provide people, places, and things with computational functionalities to support and annotate them. Using RFID-based location-tracking systems, the framework can navigate Java-based mobile agents to stationary or mobile computers near the locations of the entities and places to which the agents are attached, even when the locations change. The framework enable a mobile user to directly access his/her personalized services from stationary computing devices in the environment or from his/her portable computing devices.
