## 4 Use Cases and Application Scenarios of Internet of Emergency Services
### Public Safety  
The Public Safety scenario in the Internet of Emergency Services (IoES) involves the use of various technologies to enhance public safety and improve emergency response in situations such as criminal activities, traffic accidents, and other public safety incidents [7; 144; 145; 146; 147]. This scenario involves the coordination of multiple agencies, including law enforcement, emergency medical services, and public safety agencies.  
One example of the Public Safety scenario in IoES is the use of smart traffic management systems to improve traffic flow and reduce accidents. These systems use sensors and cameras to monitor traffic flow and identify congestion, accidents, and other hazards. The data collected from these sensors is then analyzed by artificial intelligence algorithms to make real-time adjustments to traffic patterns and reduce congestion.  
Another example of the Public Safety scenario is the use of social media monitoring tools to identify and respond to public safety incidents. Law enforcement agencies can use social media to identify potential threats and gather information about ongoing incidents. This information can then be used to coordinate emergency response efforts and ensure the safety of the public.  
In addition to these examples, IoES can also be used to improve emergency response times and enhance communication between different agencies during public safety incidents. For example, the use of location-based services can help emergency responders quickly identify the location of a public safety incident and dispatch the appropriate resources.  
Further, we discuss an example of the Public Safety scenario (Figure 7) in the Internet of Emergency Services (IoES):  
1. A concerned citizen observes suspicious activity in a public place and immediately reports it to the emergency management center through a mobile app  
Figure 6: Emergency Response scenario.  
The emergency management center receives the report and sends it to the appropriate law enforcement agency.
* The law enforcement agency receives the report and assigns a patrol car to investigate the incident.
* The patrol car arrives at the scene and confirms the suspicious activity.
* The patrol car calls for backup and requests real-time video footage from nearby surveillance cameras.
* The surveillance cameras transmit the footage to the emergency management center through a communication network.
* The emergency management center analyzes the footage using artificial intelligence and sends relevant information to the patrol car in real-time.
* The patrol car uses the information to safely apprehend the suspects and prevent any potential harm to the public.  
The Public Safety scenario in IoES has the potential to significantly improve public safety and enhance emergency response efforts. By leveraging the latest technologies, public safety agencies can more effectively respond to emergencies and protect the public from harm. However, there are also concerns around privacy and data security, which must be carefully addressed to ensure that the benefits of IoES are realized without compromising individual rights and freedoms.
