An Approach to Wireless Sensor Networks for Healthcare Scrutiny in Hospitals

Abstract

In a hospital, a system by which a patient’s physical condition and physiological parameters can be continuously monitored is essential. For example, parameters such as blood pressure (BP), cardiac rate, and fetal movements need to be taken in order to properly manage their condition. This chapter focuses on a scheme that has the ability to monitor physiological parameters from various patients. In the planned scheme, a director node is attached to the surface of the patient’s skin to gather information from the unwired sensors and transmit it to the ground station. This scheme can sense anomalous conditions and can produce a corresponding alert signal for the patient. At the same time it can pass on a message to the mobile service or send an e-mail to the patient’s general practitioner. In addition, the planned scheme contains a number of reliable, unwired relay nodes used to transmit the information passed on by the director node to the ground station. The key benefit achieved during assessment is a decrease in the energy used to extend the system’s existence, speed up and the extent to which the communication exposure to boost the liberty for increasing the patient’s life. Thus a multi-user design for infirmary healthcare has been developed and its performance weighed against existing accessible networks. It is supported by a multi-hop relay node in line with exposure to energy usage and speed.
