Proposal of ZigBee Systems for the Provision of Location Information and Transmission of Sensor Data in Medical Welfare

Abstract

This paper proposes a scheme to obtain location and vital health information using ZigBee system. ZigBee systems are wireless communication systems defined by IEEE 802.154. In the proposed scheme, location information is obtained using the Link Quality Indication (LQI) function of a ZigBee system, which represents the received signal strength. And, the vital health information are collected from the electrocardiogram monitor, the pulse and blood pressure device, attached to the patient's body. This information is then transmitted to an outside network by ZigBee systems. In this way, vital health information can be transmitted as ZigBee sensor data while patients with the ZigBee terminal are moving. In the experiments using actual ZigBee devices, the proposed scheme could obtain accurate location and vital health information from the sensor data. Moreover, to achieve high reliability in the actual service, the collected amount of sensor data was confirmed by the theoretic calculation, when a ZigBee terminal passed through ZigBee routers. These results indicate that the proposed scheme can be used to detect the accurate location of the ZigBee terminal. And over 99% of the sensor data on vital health information was obtained when the ZigBee terminal passed through approximately four ZigBee routers.

A Review on existing IoT Architecture and Communication Protocols used in Healthcare Monitoring System

“…The slave node passes on the different data readings to the sub-master node with the help of ZigBee, which is a good protocol for small distance communication, followed by the sub-master node, send the data which was received from the slave node to the master node, which is at a much greater distance and here sometimes due to lack of cellular network, therefore, LoRawan protocol has been used. The accuracy of the ZigBee protocol explained in this paper [ 15 ], during communication, such as accurate location detection by ZigBee terminal when it passes through ZigBee router area. When sensed data of patients are compared with manual reading, almost 99 percent of the matches took place.…”

Copper Nanoclusters Loaded on SA/PVA Composite Films for Sensitive Detection of Trace Water in Organic Solvent

“…SA has been widely used in the preparation of various polymer composites due to its biocompatibility, biodegradability, low cost, non-toxicity, and good film forming property. [26][27][28][29] In addition, there are a large number of free hydroxyl (-OH) and carboxylic acid (COO-) in the main chain of SA, leading to high hydrophilicity of SA. In addition, the pure SA film has rigidity and brittleness and poor mechanical properties.…”
