# Effects of Transport Network Slicing on 5G Applications
## 3 IoTalkTM Applications for 5G Use Cases
AgriTalk(tm) (Appendix A.3) is a precision farming system for soil cultivation involving MIoT (e.g., sensors for temperature, humidity, and pH), CIoT (e.g., actuators for pesticide

Figure 3c exhibits the system dashboard for agricultural sensors. The user can access the time-series graph of a sensor by simply clicking on its icon. CampusTalk (Appendix A.4) is a system that integrates a collection of MIoT applications (e.g., washing machines, dryers, parking lots, and bus scheduling), CIoT applications (e.g., smart switches, sprinklers, drippers, and lights), and MBB applications (e.g., security cameras) on campus. Note that the application for on-campus parking at NCTU uses the wireless technology NB-IoT, which is an MIoT application. (Figure 3b). IoAtalkTM (Internet of Arts; Appendix A.5) is a series of interactive art applications that allow audiences to interact with the artworks in the form of CIoT. If the artworks are animations, the actuators are MBB. HusbandryTalk (Appendix A.6) includes a series of applications for aquariums, bat farms, pig farms, lobster farms, and more. Such applications involve MIoT (e.g., sensors for temperature, dissolved oxygen, or pH), CIoT (e.g., actuators for heaters, fans, and air pumps), and MBB (e.g., cameras monitoring the aquariums). In the IoTtalkTM system, the displays for MIoT, CIoT, and MBB can be merged into a single web-based window. For example, Figure 3d exhibits the web-based display for the application PigTalk. The video screen (3) in Figure 3d is an MBB application that allows the hog farmer to monitor the farrowing pens in real-time. The dashboard (4) in Figure 3d displays the temperature and microphone status; the former is an MIoT application, while the latter is a CIoT application collecting audio data from the pigs in the farrowing pens. The control board (5) in Figure 3d is a CIoT application that allows the hog farmer to turn on or off the actuators in the pens, such as those responsible for floor vibrations, air blasts, sprinklers, and electrodes. Many piglets die in farrowing houses because they are crushed when sows roll over or lie down. If the sows does not stand up within one minute when crushing occurs, the piglet will die. To reduce the piglet mortality rate, PigTalk analyzes the raw audio data collected from the microphones. If the analysis indicates that a piglet is being crushed, IoTtalkTM will automatically trigger actuators responsible for functions such as floor vibration and water drop to force the sows to stand up. The control board also allows the hog farmer to immediately turn off the actuators in the event of a false alarm. We note that the video image obtained by the cameras can be inputted into an AI model (e.g., Yolo) to extract the image bounding box data, which can then be used together with other sensors to perform sensor fusion for behavior analysis of the sows and piglets. At NCTU, all smart applications are managed by MapTalk (see Appendix B.7), an Integrated Operations Center (IOC) application that allows users to view all IoTtalkTM applications through Google map. Similar to the way a traffic control center would employ an IOC, MapTalk serves as the IOC for all NCTU on-campus applications.
