Abstract
The Wireless Health Advanced Mobile Bio-diagnostic System (abbreviated as WHAM-BioS) project, which is supported by Taiwan’s Ministry of Economic Affairs have arisen from the need to monitor the health status of patients under long-term care programs. This thesis aims at designing and implementing an energy efficient wireless sensor network for monitoring the health status of the patients. To reduce the design and hardware complexity and power consumption of the sensor nodes, most network functionalities were concentrated in a special purposed device called Human Body Gateway (HBG) that administrates the sensor nodes of a single patient and transmit the health status of the patient forward for bioinformatics analysis. To reduce energy waste on interfered communications between sensor nodes and their HBG, network protocols were proposed in this thesis for the HBGs to insure that these communications will not interfere with each other. In addition, to further reduce the power consumption on idle listening of the sensor nodes, a power saving mechanism is proposed in this thesis. The software of the system is implemented in a layered fashion that introduces a middleware layer which abstracts the lower level functionalities of the operating system and exposes a higher level interface to the applications. The interface facilitates the applications to communicate with each other regardless where they reside to ease the implementation effort. We had implemented a health telecare system prototype based on the proposed network and layered software architecture and use Bluetooth and IEEE 802.11 for inner and inter cluster communication respectively.
