A wireless sensor network for pervasive medical supervision

The emerging of wireless sensor network has profound impacts on many fields, among which medical application is important one. Wireless biomedical sensor network can provide long-term, real-time and non-obstructive medical supervision for the patients. The large scale application of wireless medical sensor network can effectively reduce higher cost burden owing to the aging society and long term healthcare for the chronic ill. It can also enhance the quality of life for elderly people and chronic patients, and decrease the probability of medical errors. This paper presents a pervasive medical supervision system based on the wireless sensor network on the acceptable cost and application feasibility. Except for bioinformation such as the oximetry, the heart rate/pulse and the blood pressure, our system also provides some associated context data, e.g., the environment temperature, and the patient's video/picture in emergency situation which distinguishes our research with other similar systems. The design and implementation of the system composition are discussed in this paper. We also preliminary explore the network schedule mechanism of compound data transmission in this system.
