The left figure shows the Normal scenario or pre-disaster scenario where all the users are able to communicate normal way. The right-hand side figure shows the scenario after the disaster impact when the BS is damaged in a certain area. The users who are under that damaged BS not able to communicate normally. It is essential to collect information promptly about the people who are inside the damaged area. In this paper, I calculated how many people are able to communicate at different scales of disaster when using cluster-based D2D communication. |
