Design of Location-based Directory Facilitator in Context-Aware Environment

In ubiquitous computing environments, the basic information such as types or locations of services should be provided in advance to use distributed services and devices efficiently. Using a combination of developed agent technology and service discovery to efficiently and flexibly manage distributed services, devices, and users is a trend. In this paper, we analyze the DF´s searching method and designed ubiquitous location-based service in context-aware environment, because context-aware environment provides a suitable method to gather requested information in an appropriate way.
