Wireless Sensor on Patient Health Care Monitoring

As the technology development and advances in wireless communication and we are using the wireless sensor network to monitor the patient and storing the information about the patient Health conditions and alert to the physician or health care. The wearable sensor is placed on the human body and they collect the physiological Vital signs of the patient and report to the health care.Advances in wireless sensor networking have opened up new opportunities in healthcare systems. Sensor-based technology has invaded medical devices to replace thousands of wires connected to these devices found in hospitals.This paper discuss about the various issues in WSN (wireless sensor network)monitoring system the main issue can be the security and privacy when the vital signs which noted from the patient body is transfer to the appropriate health care centre at the time the data can be lost or altered by any one on the way of transmission.
