Natural disasters management using social internet of things

Natural disasters are very unexpected in human life. The best prevention from such natural disasters is an early warning system which gives a good period to take some necessary measures during the occurrence of disasters. Social media is the best medium to broadcast ominous massages and this can be done by integrating the internet of things with Social Networks. This paper proposes pre-identification of communities that may expose to natural disasters and identification of the best node where the broadcasting system can be placed. A smart broadcasting device that includes a Programmable IoT board like Raspberry Pi or Jetson Nano can be placed at a node with high centrality. The proposed work is very useful to prevent human causality by issuing early warnings of natural disasters like rain flooding, the collapse of old buildings, old bridges, earthquakes, land sliding.
