Information-Gradient Based Decentralized Data Management Over RFID Tag Clouds
The tasks in the physical environments are mainly information centric processes, such as search and exploration of physical objects. The authors have developed an informational environment, AURA that supports object searches in the physical world1. The goal of AURA is to enable individuals to use the environment in which they function as a living (short-term) memory of their activities and of the objects with which they interact in this environment. To support physical searches, the environment that the user is occupying must be transparently embedded with relevant information and made accessible by in-situ search mechanisms.
