What are the advantages of wireless sensing technology?
In the health monitoring environment, medical monitoring is a rigorous process implemented by medical professionals of all levels, but in the process of implementation by these professionals, accidental human errors cannot be avoided. In a health monitoring environment, human error should be reduced to zero, but this is usually not achieved. Therefore, in the past ten years, a lot of research work has been carried out to reduce human error in the medical process. Researchers have started with information and communication technology (lank "" ICT) to reduce human errors in the medical process. What needs to be explained is that the innovation brought by ICT is not only to improve the practicability of the automatic patient monitoring process, but more importantly The reliability of the process is greatly improved.
Wireless sensor network technology is a relatively good technology in terms of information and communication technology. It was originally used for military battlefield monitoring. Wireless sensor technology has many other applications, such as environmental learning, animal protection, production line, and building safety. The wireless sensor network can be applied to the medical environment to improve the credibility of patient monitoring.
Basically, the size of the wireless sensor device is very small, so that it can be better used to monitor the health of the patient, so as to solve the problem that it is difficult for doctors or nurses to guard the patient anytime, anywhere. At the same time, it is sure to realize the possibility of global integration, sending the important patient's health information to the handheld devices of other expert doctors through the Internet, because any doctor now has a handheld device.
Therefore, considering these aspects, it is necessary to mention wireless topology network more. It is an extension of LAN. At the same time, there is a relatively long range of communication distance in the case of a limited amount of wiring, so that important information can pass through the wireless sensor. Topological network (WSMN) is transmitted by sensors, and wireless sensor topological network (WSMN) is a combination of wireless sensors and topological networks. When the network is deployed, it also provides different functions to improve environmental monitoring capabilities.
Another ICT innovation is radio frequency identification (RFID), which is not only used for patient monitoring, but also for medical equipment, medical surgical equipment management, drug management, and management of dangerous medical items, inventory control, and Patient identification and positioning. Even when the patient is outdoors, such as in a private residence or a regular activity area, it is possible to use RFID to locate it. From these considerations, we can see that the use of RFID to monitor patients is mainly used for patient identification, location monitoring and patient medical information transmission.
In this way, the functions and initial applications of these devices can be enhanced by introducing some sensing mechanisms with RFID. Because the wireless sensory body area network (WBSN) can provide reliable infrastructure based on the network as the backbone, we now propose a novel network structure created by integrating RFID sensors and wireless topology networks (WMN), which we call RFID -WBSMN.
This framework provides a reliable network architecture for patient monitoring and identification applications, and then freely use agent technology to decide whether to notify the doctor. Use the agent technology mentioned in [10] to reduce the need to send data through the network by calculating in the network, thereby reducing the load and delay of the network. The agent is placed in a fixed position in the network and is used as an early warning system. Thereby monitoring and reporting abnormalities to specific medical workers.
Under normal circumstances, these sensors cannot perform these functions because of the limited memory and energy of these devices. In addition, the latest ICT innovation is mainly to improve the information technology (IT) system, that is, to support information dispersion through cloud technology. This technology provides users with all information technology resources as a separately paid technology. As you can see from the front, there are three services that can be implemented through cloud computing, namely architecture as a service (Iaas), platform as a service (PaaS) and software as a service (SaaS).
Therefore, looking at the equipment based on cloud technology, medical services require a good network connection and a necessary infrastructure, platform and processing software, which can be managed through the cloud to provide good medical services. At the same time, cloud services can be used by any small medical service clinics and multi-specialty hospitals. In some countries, you can purchase each medical service just like Internet services. Now researchers have begun to adopt a cloud-based electronic medical management system , using an application program interface to connect emergency department workers and hospital data from the Boston EMS rescue center.
Based on the above facts, we propose an intelligent body based on a cloud system here to identify patients and monitor physical parameters, so that the cloud is used as a warehouse to store and collect information. When the agent proposes to access sensor nodes, data collections and notify medical workers to detect abnormal sensor information. The cloud storage architecture as the backbone provides a cost-effective platform for system execution. This system integrates various medical facilities and remote patient monitoring. The remaining parts of the paper are as follows: the second part of the paper makes a survey on the research of related technologies; the third part of the paper gives a detailed description of the architecture and functions of the proposed system; the fourth part of the paper gives a summary, and An outlook for future work.
