Current advances in MEMS technology, construction of compact digital devices and improvements in design of embedded distributed systems has raised the efforts in generating various pervasive systems like healthcare ubiquitous systems for assisting patients and hospital staff to improve patient care. Inherent structures of such systems require various sensing, communication, processing, visualizing and actuating devices. Wireless communication is inherently more suitable for healthcare pervasive systems because of mobility of involved persons and devices. Due to the wide variety of used devices, various networks and communication protocols are needed for supporting them. To overcome the complexity of developing software for such systems, a cross layered software structure is required. Furthermore, due to the existence of various hardware and operating systems, a customized middleware is required to provide necessary services with proper QoS support. This paper presents above requirements on the development and running of pervasive healthcare systems.
