Hello, everyone!
Today, I would like to share with you the implementation of WBAN (Wireless Body Area Network) technology.
Here's an overview of a WBAN system built for medical uses. For the scenario depicted in Figure 1 below, hardware circuits and software programs were built.
Figure 1. In a medical center, a multi-patient monitoring scenario is depicted, with one room and one level representing one room and one floor, respectively.
Among one CCU and its sensor nodes (the first wireless link), one of several healthcare or ISM bands-MICS (Medical Implant Communication Service) or WMTS (Wireless Medical Telemetry Systems) or 433 ISM bands is to be used.
For a remote monitoring system employing a mobile network or the internet, CCUs will interact with one of the preexisting wireless protocols, such as Bluetooth, ZigBee, and WiFi. This effort resulted in the development of 2 software packages.
The GATEWAY is the name of the application running on the local PC. GATEWAY's job is to collect data from the CCU via RS232/USB cable and send it across an Ethernet network to a remote PC via TCP/IP connections.
BSN Application is the name of the software installed on the Remote PC. This BSN Application will collect data from a local computer, transform it, and store it on a remote computer for subsequent analysis by healthcare practitioners. The receiver station (i.e., the remote PC) can present all of the data collected on a User Display Graphic (GUI) and can also store all of the data in a healthcare facility's database system.
Figure 2. Multi-patient monitoring based on multi-hopping WBAN.
The above Figure 2 shows a hardware arrangement for implementing the healthcare scenario. The physiological parameters of patients are sent to intermediary CCUs, which ultimately send them to the base station. We use a multi-hopping network technology with 3 tiers of networking in the system.
I will continue to share on this article in the following post.
