Bio Medical Sensor Network for Patient Monitoring

Recent technological advances in wireless communications and wireless sensor networks have enabled the design of low-cost, intelligent, tiny, and lightweight medical sensor nodes that can be strategically placed on human body to create a Bio Medical Sensor Network (BSN) to monitor various physiological vital signs of patient for a long period of time and providing real-time feedback to the user and medical staff. Human health monitoring is emerging as a prominent application of the embedded sensor networks. In this paper, Design and Implementation of Wireless Bio Medical Sensor Network (WBSN) for patient monitoring is presented. The proposed WBSN uses miniature sensors to detect the health parameters. The attached sensors on patient’s body form a wireless bio medical sensor network and they are able to sense the various heath parameters of patient such as heart rate, temperature and sweat rate. These health parameters are then communicated to physician’s server. The physician holds various threshold values of the health parameters for each and every patient. This system can detect the abnormal conditions, issue an alarm to the patient and send a SMS to the physician.
