Abstract
In a residential or nursing home environment, using ZigBee/802.15.4 wireless network specifically to collect and gather various types of personal health data proves to be a feasible choice. The Continua Guidelines has defined both the sensor-LAN IF (sensor Local Area Network Interface) PHD (Personal Health Device) and PAN IF (Personal Area Network Interface) PHD, but only a Continua certified sensor-LAN IF PHD with Zigbee HC (Health Care) profile can connect with Continua AHD (Application Hosting Device) through Zigbee/802.15.4 network and allows data communicating between AHD and PHDs. In this paper, we present a distributed Continua AHD system design that divides the AHD device containing Continua PAN IF into Continua AHD Host and Continua AHD Gateway with communication through ZigBee/802.15.4 network. Under this structure, a Continua PHD connects with a Continua AHD Host through Continua AHD Gateway within ZigBee/802.15.4 network. One immediate advantage of the proposed system is that both of the Continua sensor-LAN IF and PAN IF PHDs can connect with Continua AHD (Host) through ZigBee/802.15.4 network. To further address the QoS (Quality of Service) issue for Continua PAN IF message transmission in a ZigBee network, we present a software approach to automatically determine the types of packet transmitted and execute Continua QoS control. Together with the QoS mechanism in the enhanced ZigBee MAC Layer, this approach realizes a complete Continua QoS control mechanism for the distributed AHD system.

This paper describes an innovative system design that focuses on the communication interface standards between AHD (Application Hosting Device) and PHD (Personal Health Device) of the interoperable standard interfaces in Continua Personal Health
Summary
The impacts of aging population and gradual insufficiency of medical resources have motivated the health industry to search for more efficient healthcare delivery mechanisms in recent years. This arrangement extends the transmitting distance between AHD and PHD to a wider coverage of ZigBee/IEEE 802.15.4 network It is expected in our design approach that a Continua AHD can simultaneously connect all PHDs on both sensor-LAN IFs and/or PAN IFs to aggregate biometric signals and data in residential or nursing home environment with existing. Since QoS (Quality of Service) plays a major role in the transmission of biometric signals in Personal Health, the Continua Guidelines has described six combination values for parameters in the QoS bin for the transmission of biometric signals in Personal Health based on the two QoS requirements: reliability and latency With reference to these six QoS bin requirements; we suggest a method in this paper to automatically determine the required QoS Control Parameters in transmitting Continua PHD messages between the corresponding Continua AHD Host and Continua. A conclusion will be provided at the Section 4
