An Experimental Investigation on Communication Interference and Mitigation during Disaster Using Lifi Technology

Communication during disaster plays a vital role. In this paper, a system is proposed to provide communication during disaster like earthquakes, sandstorms, tsunamis floods. etc when disaster happens it causes a black-out in communication, a serious of network failure which could cause the delays in rescue team especially in remote areas. The foremost important thing is generating the first response from the people or family who had a close encounter to that if it gets broken then communications with other people's get collapsed which lead to major impact to society by natural calamity. Li-Fi is a booming technology and plays a role on this scenario with the speed of transmission is up to 150mbps. This idea has been implemented as a demo using Arduino Uno processor with bit transfer and receives via serial communication ports. The bits are transmitted as a pack of 8 bits and they are sent in a binary encoded format. Then the primary parameters such as BER, MSE, and PSNR are computed for the different field of distance by varying the position of Light source. Further, to enhance the modern trending technology, a mobile app was developed which act as an emergency alert system where they can alert the team at the initial stage of disaster begins, within a fraction seconds information will be shared to the team with high speed of approx 150 Mbps with high PSNR and low value of MSE. They can also report the current scenario to natural disaster management authority.
