Pervasive health care applications envision sensor rich computing and networking environments that can capture various types of contexts of patients (or inhabitants of the environment), such as their location, activities and vital signs. Such context information is useful in providing health related and wellness management services in an intelligent way so as to promote independent living. In this talk, our approach towards an energy-efficient determination of an individual's context (both physiological and activity) for assisted living environments will be discussed. Given the expected availability of multiple sensors, context determination may be viewed as an estimation problem over multiple sensor data streams. An optimization technique allowing the context service to compute both the best set of sensors and their associated sensing parameters (e.g., tolerance values) while ensuring acceptable accuracy of the derived context at a minimum communication cost will be discussed. Experimental results from our evaluation using SunSPOT (Sun Small Programmable Object Technology) sensors to demonstrate the potential impact of this approach will also be presented. At the end, the Speaker will discuss his future research plans and directions in this field.

All interested persons are welcome to attend the Meeting :
