Design of wireless network of sensors for continuous monitoring of vital biosignals

The concept of a wireless integrated network of sensors, already applied in several sectors of our everyday life, such as security, transportation and environment monitoring, can provide an advanced monitor and control medium for healthcare services. By networking medical sensors wirelessly, we create the appropriate infrastructure for continuous and real-time monitoring of the patient without discomfort. Moreover, the utilization of existing mobile communications networks in such an application releases patient´s telemonitoring services from almost any spatial constraint. In this paper we describe the architecture of a modular and ambulatory telemedicine system used for continuous monitoring of vital biosignals. We focus on the design of the wireless network of medical sensors, attached to the patient´s body, with emphasis being given to the software and hardware infrastructure that supports the communication between the nodes.
