These give rise to a new generation of intelligent applications. Sensor data about the target of observation or the environment are essentially the insights to enable effortless interactions between the users and applications. The emergence of sensor network technology would impact a broad variety of applications from national security to infrastructure monitoring. In this project, we seek the applications of sensor networks in the domain of consumer electronics, and in particular intelligent home care. In that, the sensor networks play the critical role of collecting sensor data that indicate the well being of the elders living in place. The design of sensor network for home care is unique in three aspects – co-existence of static and mobile sensors, variety of data types, and mission-criticalness of data for elder care. Emphasizing both the engineering innovation and practical business solution, we propose 1) adaptive diffusion, 2) fast content-based forwarding, and 3) two-class service differentiation that address the above three challenges. The adaptive diffusion is a data-centric path finding (routing) mechanism, which prefers the selection of stable and energy-abundant routes. The fast forwarding algorithm handles, in low space and time complexity, the content-based table lookup problem. The service differentiation enables mission-critical data to be sent in high priority and redundancy. Our objectives in this project are to systematically evaluate, validate, implement, and integrate the sensor network to the overall home care system – iCare. We expect, as a result, to lead the world in the research and development of sensor network based intelligent home care system. The expertise built up by the project will put Taiwan at a vintage point in the R&D of sensor networks in consumer electronics. This will also pave a brand new avenue for System on Chip (SOC) design and inspire a new generation of consumer demands for ubiquitous intelligent applications.application/pdf101103 bytesapplication/pdfzh-TW國立臺灣大學電機工程學系暨研究所reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/8058/1/932218E002147.pdf
