A Systematic Literature Review of Wireless Sensor in Safety Application

With the rapid development of wireless sensor technology, wireless sensors have the potential to be applied in various fields. The introduction of wireless sensors in safety application is one of the feasible applications. The wireless sensors can be used to monitor human and environment to avoid potential safety issues. In this study, a systematic literature review was conducted by software like VOSviewer, CiteSpace, Harzing’s Publish or Perish, MAXQDA and Mendeley. A trend analysis was conducted. It was found that the wireless sensors in the safety application are becoming increasingly popular. However, compared with a large number of wireless sensor papers, there is still a lot of research space in the safety application. The engagement measurement by Vicintas showed there is a lot of room for popularization of wireless sensors for safety in daily life. A co-citation analysis demonstrated the three clusters of wireless sensors in the safety application: wireless sensor network, location privacy and communication protocol. The citation burst analysis showed the trend has shifted from sensor network design to location privacy, Internet of Things (IoT) and applications. The Content Analysis listed the most frequent words from 15 selected key articles (such as data, node, network, monitoring). It can be concluded that safety applications of wireless sensors are increasing, and there is still a lot of work to be done.
