Aware service base on the assembly of multiple weak location sensors

Indoor location information is important for the awareness computing environment. One single location sensor always is not accurate and applicable enough for providing the right service to the user. In this paper, an OSGi based simulation system is introduced firstly, and then we propose a framework to support the combination of several weak location sensors. With this combination model, multiple weak location sensors can work together to provide the better location aware service to the user. The experiment platform which consists of RFID array location sensor, RF sensor, pressure sensor and other sensors can work together in the OSGi based simulation system, experiment results show that the assembly of multiple weak sensors do better than the solo sensor. It can help the designers to achieve the better cost-performance for the awareness applications between various possible combinations.
