Outline Introduction Issues Motivations Goals Technology IP Multimedia Subsystem (IMS) Wireless Sensor Networks (WSNs) Approaches Simulation Conclusions

Issues With the increase in life expectancy and the number of aging populations, there is a significant interest in wireless healthcare applications that could improve the quality of life of elderly and chronically sick people.

Motivations Combining the capabilities of WSNs(Wireless Sensor Networks) and the IMS(The IP Multimedia Subsystem) opens the door to a wide range of personalized and adaptive value added services for 3G users. Wireless healthcare is one of the important application areas that can benefit from the combined IMS/WSNs capabilities.

Goals We focus on this application area and present a case study on the design and implementation of a context-aware IMS wireless healthcare application, that leverages the capabilities of our WSN/IMS integration solution.
