The evolution of the technology in sensors, low-power integrated circuits, and wireless communications have made the design of low-cost, miniature, lightweight, and intelligent physiological sensor nodes. These nodes have multi-capabilities like sensing, processing, and communicating, there is one or more vital signs can be integrated into wireless personal or body networks (WPANs or WBANs) without being seen for health monitoring. Hopes are relying on these networks to revolutionize health care by providing inexpensive, non-invasive, continuous, ambulatory health monitoring with almost real-time notification of medical records via the Internet, Wi-Fi, 3G networks or any other wireless network. That is the reason why there a number of researches being made for focusing on various technical, economic, and social issues, after all, still there is many technical difficulties need to be passed in order to have flexible, reliable, secure, and power-efficient WBANs suitable for medical applications. In this paper we’ll discuss system architecture for smart healthcare based on an advanced Wireless Sensor Network (WSN). It specifically targets assisted-living residents and others who may benefit from continuous, remote health monitoring .Also we’ll introduce a general WBAN system architecture and a developed one. This paper also presents best practices in wireless sensor network design for health care applications; Based on the most important aspects like power efficiency and security which guide the development of a wireless sensor network based applications.
