SAHMS- Scatternet Assisted Health Monitoring System

Wireless Sensor Networks (WSN) is one of the accelerated technologies which consign solutions to critical application environments. It allows the integration of medical sensors to form a group scenario which makes it viable to remotely collect and communicate the physiological signals of a patient, thus preventing the patient from being tied to a particular set of monitoring medical instruments and thereby facilitate the patient’s prior acquittal from the hospital. The medical sensors used are integrated with Bluetooth radio technology and further allowing the sensor nodes to form a Wireless Body Area Network (WBAN). Use of Bluetooth technology limits the number of sensor nodes to be attached to the human body as seven (piconet). So in order to increase the number of sensor nodes that is adhered to the human body using Bluetooth radio technology a scatternet of sensor nodes i.e. network of piconets can be formed. To create such a network on the body, initial analysis of WBAN has been done. We already proposed a framework for WBAN which discusses the working of the WBAN in three phases and the parameters which influence the working of each phase. This paper discusses the implementation the first phase of the framework and analyzes the extent to which the scalability of bio sensors is supported by the framework when a scatternet of sensor nodes is formed by checking the performance
