![]() As a result, misleading signals are generated. The transmitter emits signals to the surrounding environment, although the signs are generally reflected due to walls and metal elements. In comparison to room size, the most critical components impacting RSSI during the development of indoor positioning algorithms are walls, metal materials, and water. In most cases, Bluetooth RSSI is used in indoor positioning technology. This technology separation is also known as proximity detection. This can also be accomplished by adjusting device distances between cellphones. Using location information to track close contacts is not the only method. ![]() The idea of our paper is to use Bluetooth RSSI from smartphones for proximity detection for close contact tracking. Bluetooth RSSI is precisely one of the mobile sensor data. Reference also uses mobile sensor data to track close contacts. ![]() Based on mobile sensor data from Smart Contact Tracking, 627,386 potential contacts related to Diamond Princess cruise ship passengers were identified by using location methods and analysis after cross validation with other sensor monitoring data. Using smartphone location data to track close contacts is an excellent approach to finding them. Finding and isolating close contacts is critical to halting COVID-19 rapid spread. Those with confirmed COVID-19 and close contacts are the two main groups of people who will need to be quarantined. Isolation is still one of the most effective ways to keep COVID-19 from spreading rapidly today. Infectious diseases are more prone to spread quickly in this setting due to ships’ restricted and limited interiors.
