When it comes to choosing the best wireless protocol to transmit realtime patient data from a sensor, ZigBee is the obvious choice. This wireless technology has many benefits including low data rate, long battery life, and secure networking. Additionally, it is easy to use and support many network topologies and large numbers of nodes. ZigBee is currently used in many medical applications. The protocol can be secured with three levels of security.
ZigBee is a secure wireless protocol
Using ZigBee, medical devices can communicate over short distances, including over 100 meters. The protocol supports 2.4 GHz, 915 MHz and 868 MHz frequencies, and it operates at low data rates. The low data rate makes it ideal for low-power applications, such as pulse monitoring or body temperature monitoring. However, its low data rate makes it an inferior choice for higher-end medical devices.
Its high-level security allows for real-time data to be securely transmitted between medical devices. To make sure data security, ZigBee sensors use a secure wireless protocol called STS. This protocol uses a key agreement scheme, based on the Diffie-Hellman algorithm. The data is encrypted and transmitted using an encryption key agreement scheme that is agreed upon by all the sensors and the local coordinator.
Bluetooth is a short-range wireless protocol
The Bluetooth technology is a short-range wireless communication standard that uses ultra-high frequency radio waves to connect devices. It has a range of about 100 meters and offers a wide variety of advantages for medical devices. Bluetooth technology is also energy efficient and inexpensive, and has minimal interference among connected devices. Bluetooth is widely used in consumer electronics and medical devices, such as pacemakers, blood pressure monitors, and other sensors.
Depending on the type of medical sensor, the data rate required varies from a few kbps to hundreds of kbps. The data rate required for glucose monitoring, for example, will depend on the patient’s weight, body temperature, and other factors. Other medical applications, such as electrocardiograms and oxygen saturation monitoring, may require a higher data rate.
SIGFox is a low-power, low-cost solution for connecting sensors and other devices. Its signature-based authentication and virtual private network provide the security necessary to protect data. SigFox also has a built-in firewall to protect data while in transit. Also has encryption to protect against unauthorized access.
SigFox is also a secure wireless protocol that ensures the accuracy of the realtime patient data from sensor nodes. The protocol replicates settings from the sensor node to ensure that predicted values match those in the server. This allows for the transfer of patient data from one device to another without any fear of loss of information. The safety of SigFox is one of the main reasons why this wireless protocol is the safest wireless protocol for transferring realtime patient data from sensor to server.
The proposed system for transferring realtime patient data relies on wireless communications. It consists of two embedded devices: a Raspberry Pi with a ZigBee transceiver module, a 16 x 2-inch LCD screen, a buzzer, a keyboard and a mouse, and an Arduino Mega 2560. The Raspberry Pi communicates via ZigBee to a second device, which fixes a ZigBee transceiver module to the Arduino through a ZigBee shield.
The benefits of wireless communication for medical monitoring systems are clear. With real-time physiological signals, doctors can monitor patients in real-time. These signals include blood pressure, heart rate, oxygen saturation, body temperature, and weight. To transmit such data reliably, systems must be designed for low data latency and high reliability. Adaptive features are essential in medical devices to minimize system failures. The communication infrastructure must also be reliable and provide high quality of service.
There are several reasons why Li-Fi wireless protocol is preferred for transferring realtime patient data from sensor. The main benefits of Li-Fi include high data transfer rates, low latency, and security. Its high integration rate allows it to be applied to every kind of light source and various interested parties. Compared to other wireless protocols, Li-Fi is inexpensive, flexible, and can be adapted to any environment.
Another reason for using Li-Fi is the fact that it is more secure than WiFi. This is because it is not susceptible to electromagnetic interference. Li-Fi devices do not need a cellular connection, and the light is dim enough to be barely visible when not in use. This feature of Li-Fi also makes it suitable for sensitive environments such as hospitals and laboratories. In addition, the technology is extremely safe for the eyes and skin.
