Multipoint wireless network for complex patient monitoring based on embedded processors

Abstract

The present paper presents an approach to the patients or elderly persons monitoring able to oversee some vital signs for more persons in a delimited area. The system is able to collect also the images of patients. Wireless sensors networks (WSNs) became a successful alternative to cabled systems used for surveillance or monitoring. The system is based on the ZigBee wireless technology and using a low-cost Beagle Board, designed with the DM3730 embedded processors. Even if the data rates provided by the ZigBee technology are not very high the application proposed can be successfully achieved using this low-cost approach.
