Indoor Localization Systems — Tracking Objects and Personnel with Sensors, Wireless Networks and RFID

Hybrid Zigbee RFID sensor network for humanitarian logistics centre management

“…The compatibility of various RFID devices to WSN network and the feasibility of using WSN protocol to performance active RFID service have been demonstrated in our previous work . Our recent work also demonstrated the capability of such architecture to be further extended for real-time tracking service (Yang & Yang, 2009a, 2009b. Because of the poor performance of standard passive RFID tags when they work with materials containing metal and water, active tags are recommended for tracking vehicles, engineering plants, large special rescue equipments and people in the scenario.…”

Smart and flexible manufacturing systems using Autonomous Guided Vehicles (AGVs) and the Internet of Things (IoT)

“…The IoT signifies that items and objects can be connected, tracked, and monitored, which allows manufacturers to automate their production systems and increase performance (Agrifoglio et al, 2017) IoT can revolutionise the indoor positioning of AGVs in a manufacturing system and potentially improve manufacturing efficiency (Moreira and Mautz 2013). However, the technology providing indoor positioning with less than 1-meter accuracy is currently considerably expensive compared to current manufacturing practices that depend on fixed local infrastructure and mobile units such as AGV (Yang and Yang 2009). Despite the advantages, IoT remains expensive and complex, reducing its diffusion among the majority of manufacturing companies which are small and medium enterprises (Moeuf et al 2018).…”

An integrated information management model for proactive prevention of struck-by-falling-object accidents on construction sites

“…Yang and Yang (2009a) classified the various in-door location tracking technologies in three categories: the non-RF technologies, active-RF technologies and passive-RF technologies. Passive-RF technologies are usually used for special applications such as robot tracking.…”
