A distributed wireless body area network for medical supervision

The emerging of wireless body area network has profound impacts on our daily life, such as pervasive medical supervision and outdoor exercises, and the large scale application of wireless body area network can effectively reduce higher cost burden owing to the aging society and long term healthcare for the chronic illness. It can also enhance the quality of life for elderly people and chronic patients, and decrease the harm of the sudden diseases. The paper presents a distributed wireless body area network for medical supervision. The system contains three layers: sensor network tier, mobile computing network tier, and remote monitoring network tier. It provides collection, demonstration, and storage of the vital information such as ECG, blood oxygen, body temperature, respiration rate. Furthermore, it also provides medical service management and disease warning. The system has many advantages such as comfort, low-cost, low-power, easy configuration, convenient carrying, easy transplantation, real-time reliable data, and friendly human-machine interaction. And then the design and implementation issues of the system composition are discussed in this paper.
