Wireless Sensor Network and Sensor Fusion Technology for Ubiquitous Smart Living Space Applications (Invited Paper)

This paper describes wireless sensor network (WSN) and sensor fusion technology designed for ubiquitous smart living space applications. With respect to the WSN technology, a new standard from the Zigbee alliance is introduced. This new standard is designed to help constructing the network infrastructure by integrating with the TCP/IP network with the ZigBee network. A new approach for WSN deployment based on this new standard is also presented. With respect to the sensor fusion technology, this paper presents a smart sensing and control algorithm that naturally adjusts the thermal quality of the environment according to the interior and exterior environmental factors and the behavior of the inhabitants in a smart skin environment. The experiment results indicate that the proposed algorithm significantly improves the thermal comfort and effectively reduces energy consumption.
