These disasters have shown how crucial it is to have reliable communication for rescue operations. Often, disasters damage communication network. The heavy demand for data transfer on the Internet is pushing its infrastructure to the limit, making it difficult to respond quickly to emergencies and disasters. To solve this problem, Internet networks need to prioritize certain types of data traffic: Security, Health, and Emergency (SHE) data traffic. These specialized networks work in private domains to support specific tasks for particular groups of users. We proposed network flow priority management system based on Software-Defined Networking (SDN) to give SHE data traffic the highest priority. Using the Mininet simulator, we tested our system extensively. The results show significant improvements in handling SHE data traffic, ensuring that during network congestion, SHE data is transmitted quickly, improving the effectiveness of emergency response efforts.
