On the study of a ubiquitous healthcare network with Security and QoS

As a consequence of rapid technological development, the normally isolated medical sensor platform is gradually being integrated into networks. However, most ubiquitous or mobile health systems are lacking a system that combines both network security and QoS (Quality of Service). In this paper investigates the possible security and QoS methods of a ubiquitous healthcare (U-healthcare) network platform in OSI (Open System Interconnections)-layers. This network platform is based on the Wireless Overlay Networks (WON) Bluetooth, 802.11 and 802.16 over IPv6 Network, and provides a secure and stable U-healthcare platform by including the application of healthcare sensors with RFID, U-healthcare PDA VoIPv6, falling detection, and patient orientation.
