The paper presents an approach for location-aware communications in ubiquitous computing environments. It is constructed on a symbolic location model, which links everyday objects, including non-smart objects and places, with counterpart objects, which are executable software components that are dynamically organized like a tree based on geographical containment, such as in a user-room-floorbuilding hierarchy. The approach enables physical entities and places to communicate with one another

This paper presents the design for the approach and describes an implementation of it. Approach Many researchers have explored location models for the physical world and existing ones can be classified into two: physical-location and symbolic-location [2, 6]. The former represents the position of people and objects as geometric information. A few outdoor-applications like movingmap navigation can easily be constructed on such physical-
