Role of Wireless Sensor Networks in HealthCare

Abstract

In modern world the wireless sensor networks (WSN) will strive to provide effective helps to the physician as well as patients. Because in a hospital necessary to constantly monitor the patient’s physiological parameters such as sound, heart rate, pressure, temperature, blood pressure and so on..The use of wireless sensor networks (WSN) in healthcare applications is growing in last few years and the system coordinator node has attached on patient body to collect all the signals from the wireless sensors and sends them to the appropriate base station (BS). The attached sensors on patient’s body form a wireless body sensor network (WBSN) and they are able to sense the heart rate, blood pressure, pressure, temperature and etc. This system can find the abnormal conditions, and issue an emergency alarm to the patient and send a SMS/E-mail to the physician and hospital administration. And the wireless sensor system consists of several wireless relay node which are responsible for relaying the data sent by the coordinator node and forward them to the base station. The main advantage of this system in comparison to previous systems is to reduce the energy consumption to prolong the network for long life, speed up and extend the communication coverage to increase the freedom for enhance patient quality of life. Here we have developed this system in patient architecture for hospital healthcare and compared it with the other existing networks based on multi-hop relay node in terms of coverage, energy consumption and speeds.
