Preparedness for managing pandemic using distributed mobile brokers - Using COVID 19 use case.

Area of Science:

• Computer Science
• Information Systems
• Network Engineering

Background:

• The COVID-19 pandemic highlighted critical challenges in accessing essential services like medical care, food, and oxygen.
• Lockdowns and quarantines severely restricted people's ability to obtain necessary resources, leading to widespread hardship.

Purpose of the Study:

• To propose a distributed mobile broker service using the MQTT protocol for managing and accessing essential services during a pandemic.
• To enhance the reliability and efficiency of essential service delivery in crisis situations.

Main Methods:

• A distributed mobile broker system architecture was designed, dividing cities into manageable areas.
• Essential service providers register with publishers, and seekers utilize mobile brokers to access these services.
• A data-aware trajectory planning technique was implemented for mobile brokers to minimize data collection delay.

Main Results:

• The proposed system was evaluated under two scenarios: mobile brokers with fixed subscribers and mobile brokers with mobile subscribers.
• Performance analysis focused on key metrics including delay and packet delivery ratio, comparing against fixed broker conditions.

Conclusions:

• The distributed mobile broker service effectively manages and facilitates access to essential services during pandemics.
• The data-aware trajectory planning enhances the efficiency of mobile brokers, reducing delay and improving packet delivery, crucial for crisis management.
